Elevator Magnetic Strip SWEET: Precision Sensing Core from Nanjing Zhuye Elevatorparts

Elevator Magnetic Strip SWEET is a high-precision magnetic sensing component widely used in elevator door systems and leveling devices, serving as a “position marker” for elevator operation. It provides stable magnetic signals to cooperate with sensors (e.g., door edge sensors, leveling sensors) to achieve accurate door opening/closing control and precise floor positioning. This magnetic strip features uniform magnetic force distribution, strong anti-interference capability, and excellent environmental adaptability, directly affecting the responsiveness of the elevator door system and the accuracy of leveling. Exclusively supplied by Nanjing Zhuye Elevatorparts, a professional and trusted provider of high-quality elevator components, the Elevator Magnetic Strip SWEET fully complies with international elevator safety standards (EN 81-20, GB 7588) and magnetic component technical specifications. With reliable magnetic stability, wear resistance, and long service life, it is widely applied in residential buildings, commercial complexes, office towers, airports, and other public facility elevators worldwide.

Nanjing Zhuye Elevatorparts adheres to the core philosophy of “Stable Magnetism, Precision Sensing” and implements strict quality control throughout the production and inspection process of the SWEET elevator magnetic strip. Each unit undergoes a multi-stage pre-delivery inspection, including magnetic force intensity testing, magnetic distribution uniformity verification, temperature stability detection, and corrosion resistance trials. The magnetic strip adopts premium materials and advanced manufacturing technology: it is made of high-quality ferrite or neodymium-iron-boron magnetic material, ensuring stable magnetic force output (magnetic induction intensity 100–300mT, subject to specifications) and low magnetic attenuation (≤ 5% after 5 years of use); the surface is covered with a high-wear PVC or stainless steel protective layer, effectively resisting friction, impact, and chemical corrosion; the back is equipped with high-strength adhesive (3M adhesive as standard) for convenient and firm installation. With standardized dimensions (width 10–20mm, thickness 1–3mm, customizable length) and flexible cutting performance, the SWEET magnetic strip can be perfectly matched with various elevator sensor systems without additional modifications.

Step-by-Step Usage Guide for Elevator Magnetic Strip SWEET

To maximize the sensing accuracy and service life of the Elevator Magnetic Strip SWEET, and to ensure the safe and stable operation of the elevator system, strictly follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, debugging, and maintenance:

1. Professional Selection & Installation

Installation must be conducted by certified elevator technicians proficient in elevator sensing systems. Prior to installation, refer to the compatibility manual provided by Nanjing Zhuye Elevatorparts to confirm that the SWEET magnetic strip’s specifications (magnetic force, dimensions) match the target elevator’s sensor model and application scenario (door edge protection, leveling positioning, etc.). The installation steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and lock the power switch to prevent accidental power-on. For door edge magnetic strips, fix the elevator door in the fully open position with a door holder; for leveling magnetic strips, operate the elevator car to the middle floor and fix it with mechanical supports. Clean the installation surface (door edge, guide rail, or car frame) to remove dust, oil stains, and debris, ensuring the surface is flat and dry.
Cutting & Positioning: According to the actual installation length requirement, use a hacksaw or scissors to cut the SWEET magnetic strip (note: avoid damaging the magnetic material inside). Mark the installation position on the mounting surface according to the elevator sensor’s induction range, ensuring the magnetic strip is aligned with the sensor’s sensing surface (alignment deviation ≤ 2mm).
Adhesive Installation: Tear off the protective film on the back of the magnetic strip, align it with the marked position, and press it firmly from one end to the other to ensure full contact between the adhesive and the mounting surface. For key positions (e.g., door edges with frequent movement), use stainless steel screws for auxiliary fixing to enhance installation stability. After installation, let the adhesive cure naturally for 24 hours before starting the elevator.

2. Debugging & Function Test

Debugging and function testing are crucial to ensure the SWEET magnetic strip cooperates with sensors reliably. Follow these steps with reference to Nanjing Zhuye Elevatorparts’ technical guidelines:

Induction Signal Test: Restore the elevator’s power supply and switch to inspection mode. Use a gaussmeter to detect the magnetic induction intensity of the installed magnetic strip, confirming it meets the sensor’s working requirements. For door edge magnetic strips, move the sensor along the magnetic strip to check if the sensor outputs stable induction signals.
System Coordination Test: For leveling magnetic strips, operate the elevator to move up and down slowly, checking if the elevator can stop accurately at each floor (leveling deviation ≤ 2mm). For door edge magnetic strips, test the door closing process—ensure the elevator door reverses immediately when encountering obstacles (triggering the magnetic strip sensor) to avoid clamping passengers.
Stability Test: Conduct 50 consecutive elevator operation tests (including door opening/closing and leveling) to confirm the magnetic strip does not shift or fall off, and the sensor maintains stable induction without false signals or signal loss.

3. Daily Operation & Routine Maintenance

Regular inspection and maintenance are essential to early fault detection and ensuring the long-term stable operation of the SWEET magnetic strip. Maintenance personnel should integrate the following checks into their daily patrol routines:

Daily Visual Inspection: During elevator patrols, check the external condition of the magnetic strip. Ensure the protective layer is intact without scratches, peeling, or wear; the magnetic strip is firmly installed without shifting, warping, or falling off; the installation surface is clean without heavy dust or oil stains. For door edge magnetic strips, pay special attention to whether the magnetic strip is damaged by collision.
Weekly Signal Test: Use a gaussmeter to detect the magnetic induction intensity of the magnetic strip, confirming it is within the standard range. Check the cooperation between the magnetic strip and the sensor—if the sensor has poor induction or false triggers, clean the magnetic strip surface and adjust its position in time.
Monthly Cleaning & Maintenance: Clean the surface of the magnetic strip with a soft, dry cloth or a cloth dipped in neutral detergent to remove dust, oil stains, and debris. Avoid using sharp tools or corrosive cleaning agents to prevent damaging the protective layer. For magnetic strips with loose installation, re-press them or add auxiliary fixing screws. For areas with severe humidity, check the magnetic strip for rust and replace the protective layer if necessary.

Recommended Replacement Cycle for Elevator Magnetic Strip SWEET

As a core sensing component enduring long-term environmental erosion (humidity, dust, temperature changes), mechanical friction, and magnetic attenuation, the Elevator Magnetic Strip SWEET has a specified service life. Timely replacement is critical to avoiding faults such as reduced magnetic force, uneven magnetic distribution, or protective layer damage—issues that may cause sensor induction failure, leading to elevator door closing errors, inaccurate leveling, or even safety hazards.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily door opening/closing cycles ≥ 2000, environment temperature -20–60℃, humidity 10%–95%), the recommended replacement cycle for the SWEET magnetic strip is 4–5 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, magnetic attenuation tests, and global user feedback on elevator sensing systems.

2. Adjustments for Special Scenarios

Harsh Environments & High-Traffic Scenarios: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust industrial sites, or ultra-high-traffic locations (e.g., large airports, central shopping malls) with daily door cycles ≥ 3500, the replacement cycle should be shortened to 2–3 years. Harsh conditions and frequent use accelerate the wear of the protective layer and magnetic attenuation, significantly reducing the magnetic strip’s reliability.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable environments (constant temperature and humidity), the replacement cycle can be extended to 5–6 years—only if Nanjing Zhuye Elevatorparts’ professional technicians conduct an inspection and confirm that the magnetic strip’s magnetic induction intensity, distribution uniformity, and protective layer integrity meet the original factory standards.

3. Immediate Replacement Conditions

Replace the SWEET magnetic strip immediately if any of the following issues occur, regardless of its service life:

The magnetic induction intensity decreases by more than 30% compared with the original factory standard, leading to sensor induction failure or unstable signals.
The protective layer is severely worn, peeled off, or the magnetic material inside is exposed, leading to rust or magnetic leakage.
The magnetic strip is severely warped, shifted, or broken, and cannot be fixed by adjustment, affecting the normal operation of the sensor.
Professional testing confirms that the magnetic distribution is uneven, causing the elevator to have inaccurate leveling or abnormal door opening/closing, which cannot be resolved by repositioning the magnetic strip.

In conclusion, the Elevator Magnetic Strip SWEET supplied by Nanjing Zhuye Elevatorparts is a high-quality, reliable sensing component tailored for modern elevator systems.
