Elevator Leveling Magnetic Strip 250208: Precise Positioning Core from Nanjing Zhuye Elevatorparts

Elevator Leveling Magnetic Strip 250*20*8 is a key positioning component for elevator leveling systems, providing accurate position signals for elevators to ensure they stop precisely at floor landings. With a standard size of 250mm (length) × 20mm (width) × 8mm (thickness), this magnetic strip is compatible with mainstream elevator leveling sensors (inductive, Hall effect) and is widely used in residential buildings, commercial complexes, office towers, airports, and industrial elevators. It delivers stable magnetic performance, strong anti-interference capability, and excellent environmental adaptability, ensuring precise elevator leveling even in harsh shaft environments. Exclusively supplied by Nanjing Zhuye Elevatorparts, a professional and trusted provider of high-quality elevator components, this Elevator Leveling Magnetic Strip 250*20*8 fully complies with international elevator safety standards (EN 81-20, GB 7588) and magnetic component technical specifications. Crafted with premium magnetic materials and advanced processing technology, it maintains stable magnetic flux for long-term use, laying a solid foundation for the safe and comfortable operation of elevators.

Nanjing Zhuye Elevatorparts adheres to the core philosophy of “Precise Positioning, Stable Performance” and implements strict quality control throughout the production and inspection process of the 250*20*8 leveling magnetic strip. Each batch undergoes multi-stage pre-delivery inspections, including magnetic flux density testing, dimensional accuracy verification, high-temperature and humidity resistance detection, and adhesion strength testing. The magnetic strip adopts advanced materials and technology: the core is made of high-performance ferrite or neodymium iron boron magnetic material, with a surface magnetic flux density of 120–180mT to ensure stable signal transmission; the surface is coated with a high-temperature resistant PVC or epoxy resin layer, which is corrosion-resistant, scratch-resistant, and aging-resistant, adapting to the humid, dusty, and temperature-varying environment of elevator shafts (-20℃ to 80℃); the standardized 250*20*8 size and pre-designed mounting holes enable seamless matching with elevator guide rails and sensor systems, simplifying installation and replacement processes.

Step-by-Step Usage Guide for Elevator Leveling Magnetic Strip 250208

To maximize the positioning accuracy, service life, and operational stability of the Elevator Leveling Magnetic Strip 250*20*8, strictly follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for selection, installation, and maintenance:

1. Professional Selection & Installation

Installation must be conducted by certified elevator technicians proficient in leveling systems. Prior to installation, refer to the compatibility manual provided by Nanjing Zhuye Elevatorparts to confirm that the 250*20*8 magnetic strip matches the elevator’s leveling sensor model, guide rail type, and floor height. 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. Use a hoisting device to stabilize the elevator car at the maintenance position and fix it with mechanical supports. Clean the mounting surface (elevator guide rail or shaft wall) at each floor landing to remove dust, oil stains, and debris, ensuring a smooth and dry mounting base.
Position Marking: According to the elevator’s leveling parameter requirements and Nanjing Zhuye Elevatorparts’ installation guidelines, mark the mounting position of the magnetic strip on the guide rail or shaft wall. Ensure the center line of the magnetic strip is aligned with the elevator’s leveling sensor (alignment deviation ≤ 2mm) and the distance between the magnetic strip and the sensor is 5–10mm (consistent with the sensor’s working range).
Magnetic Strip Installation: Tear off the protective film on the back of the 250*20*8 magnetic strip (with pre-applied high-strength adhesive) and paste it firmly on the marked position. Reinforce it with stainless steel self-tapping screws through the pre-designed mounting holes to prevent falling off due to long-term vibration. Ensure the magnetic strip is tightly attached to the mounting surface without gaps or warping. Repeat the operation for each floor landing.

2. Debugging & Function Test

Debugging and function testing are crucial to ensuring the precise positioning of the 250*20*8 leveling magnetic strip. Follow these steps with reference to Nanjing Zhuye Elevatorparts’ technical guidelines:

Magnetic Flux Verification: Use a gaussmeter to detect the surface magnetic flux density of the installed magnetic strip. Ensure the value is within the standard range (120–180mT) and the magnetic field distribution is uniform. If the magnetic flux is insufficient, check for installation deviations or replace the magnetic strip in time.
Leveling Accuracy Test: Restore the elevator’s power supply and switch to inspection mode. Operate the elevator to run up and down, stopping at each floor to check the leveling accuracy (the gap between the elevator car floor and the landing floor ≤ 3mm). Repeat the test 10 times for each floor to confirm stable positioning without deviation.
Anti-Interference Test: Simulate harsh shaft environments (e.g., electromagnetic interference from other electrical components, dust accumulation) to test the magnetic strip’s performance. Ensure the elevator still stops accurately at landings and the leveling sensor does not generate false signals.

3. Daily Operation & Routine Maintenance

Regular inspection and maintenance are essential to early fault detection and ensuring the long-term stable operation of the 250*20*8 leveling 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 at each floor. Ensure the surface coating is intact without peeling, cracking, or corrosion; the magnetic strip is firmly fixed without looseness or displacement; the mounting surface is free of excessive dust or oil stains that may affect magnetic performance.
Weekly Position & Gap Check: Recheck the alignment of the magnetic strip with the leveling sensor and the gap between them. Adjust the magnetic strip’s position immediately if deviation is found (exceeding 2mm). Clean the surface of the magnetic strip and sensor with a soft, dry cloth to remove dust and debris.
Monthly Magnetic Performance Spot-Check: Use a gaussmeter to randomly spot-check the magnetic flux density of 3–5 floors’ magnetic strips. If the value is lower than 100mT, conduct a full inspection of all magnetic strips and contact Nanjing Zhuye Elevatorparts’ technical support team for handling suggestions.

Recommended Replacement Cycle for Elevator Leveling Magnetic Strip 250208

As a core positioning component enduring long-term environmental erosion (humidity, dust, temperature changes), mechanical vibration, and magnetic aging, the Elevator Leveling Magnetic Strip 250*20*8 has a specified service life. Timely replacement is critical to avoiding faults such as reduced magnetic flux, inaccurate positioning, or signal loss—issues that may lead to elevator leveling deviation, passenger inconvenience, or even safety risks during boarding and alighting.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily leveling cycles ≥ 2000, shaft environment temperature -20–80℃, humidity 10%–95%), the recommended replacement cycle for the 250*20*8 leveling magnetic strip is 5–7 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, magnetic aging tests, and global user feedback on elevator leveling 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 leveling cycles ≥ 3500, the replacement cycle is shortened to 3–4 years. Harsh conditions accelerate the aging of the magnetic strip’s coating and the attenuation of magnetic flux.
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 shaft environments (constant temperature and humidity), the replacement cycle can be extended to 7–8 years—only if Nanjing Zhuye Elevatorparts’ professional technicians conduct an inspection and confirm that the magnetic flux density, coating integrity, and positioning accuracy meet the original factory standards.
