Elevator Door Lock MA630-05 (Touch Point 161): Safety Interlock Core from Nanjing Zhuye Elevatorparts

Elevator Door Lock MA630-05 with Touch Point 161 is a critical safety interlock component designed for elevator landing door and car door systems, serving as the “safety guardian” to prevent elevator operation with unlocked doors. The core Touch Point 161 acts as a key electrical contact, which is closed only when the door is fully locked and opened immediately once the door is unlocked—sending real-time door status signals to the elevator main controller. This ensures the elevator can only start or run when the doors are fully locked, and stops immediately if the doors are unlocked abnormally, directly avoiding passenger falls or entrapment accidents. Exclusively supplied by Nanjing Zhuye Elevatorparts (a professional and trusted distributor of high-quality elevator safety components), the Elevator Door Lock MA630-05 (Touch Point 161) fully complies with international elevator safety standards (EN 81-20, GB 7588) and electrical contact component regulations. With reliable locking performance, stable contact conductivity, and perfect compatibility with mainstream elevator door systems, this door lock is widely applied in residential, commercial, high-speed, and industrial elevators worldwide.

Nanjing Zhuye Elevatorparts adheres to the core philosophy of “firm locking, stable contact” and implements strict quality control over the Elevator Door Lock MA630-05 (Touch Point 161). Each unit undergoes multi-stage pre-delivery inspections, including locking force verification, Touch Point 161 contact conductivity testing, wear resistance trials, and environmental adaptability detection. The product adopts high-strength structural design and premium contact materials: the lock body is made of high-quality alloy steel with surface anti-corrosion treatment to withstand long-term mechanical wear; Touch Point 161 uses silver-nickel alloy contacts with low contact resistance (≤ 50mΩ) and high wear resistance (service life ≥ 1 million times of opening/closing); the built-in mechanical interlock structure ensures firm locking without false unlocking; the IP54 dustproof and waterproof rating adapts to the humid, dusty environment in elevator shafts. Its standardized mounting dimensions and interface specifications are perfectly matched to elevator door systems, enabling quick and seamless installation without complex modifications.

Step-by-Step Usage Guide for Elevator Door Lock MA630-05 (Touch Point 161)

To ensure the reliable operation of the elevator safety interlock system and give full play to the protective role of MA630-05 (Touch Point 161), follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, adjustment, and maintenance:

1. Professional Installation & Calibration

Installation must be performed by certified elevator technicians familiar with elevator door systems. Prior to installation, confirm the compatibility of MA630-05 (Touch Point 161) with the target elevator’s door type and control system using the detailed compatibility manual provided by Nanjing Zhuye Elevatorparts. The steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and lock the power switch. Fix the elevator car to a safe position to prevent accidental movement. Clean the door lock mounting position on the landing door/car door frame to remove dust, oil stains, and debris that may affect locking accuracy.
Door Lock Installation: Fix the MA630-05 door lock to the dedicated mounting bracket using high-strength bolts provided by Nanjing Zhuye Elevatorparts. Ensure the lock body is installed horizontally (horizontal deviation ≤ 1mm) and aligned with the door hook (alignment deviation ≤ 2mm). Connect the wiring of Touch Point 161 to the corresponding interface of the elevator main controller—ensure correct polarity, tight connection, and reliable insulation.
Locking & Contact Calibration: Adjust the lock tongue position using the adjustment bolts (provided by Nanjing Zhuye) to ensure the door can be locked firmly when closed (locking force ≥ 150N). Verify the contact status of Touch Point 161: when the door is fully locked, the contact should be closed tightly (conductivity test pass); when the door is opened slightly (≥ 5mm), the contact should be disconnected immediately. Test the door opening/closing process repeatedly to confirm no false contact or poor contact of Touch Point 161.
Post-Installation Testing: Restore the power supply and switch the elevator to inspection mode. Operate the elevator to move up and down to different floors, testing the door lock’s locking performance and Touch Point 161’s signal transmission at each floor. Ensure the elevator can start normally only when the doors are fully locked, and the controller displays an alarm signal immediately if the doors are unlocked abnormally. Check for abnormal noise or jamming during door locking/unlocking—adjust the lock body position if necessary.

2. Daily Operation & Routine Inspection

Regular inspections are crucial to early detection of door lock faults and ensuring elevator safety. Maintenance personnel should incorporate the following checks into their daily patrols:

Daily Visual Inspection: During elevator shaft patrols, check the external condition of MA630-05 (Touch Point 161). Ensure the lock body is free of deformation, cracks, or corrosion; the lock tongue is flexible without jamming; the wiring of Touch Point 161 is intact without aging, wear, or loose connections. Observe the door closing process to check if the door is locked firmly and the lock indicator light is on normally.
Weekly Contact & Locking Test: Use a multimeter to detect the conductivity of Touch Point 161 (ensure contact resistance ≤ 50mΩ when closed). Test the door lock’s locking force with a force gauge to confirm it meets the standard (≥ 150N). Simulate abnormal door unlocking (e.g., manual forced unlocking) to check if the elevator stops immediately and sends an alarm signal.
Monthly Cleaning & Lubrication: Clean the lock body, lock tongue, and Touch Point 161 with a professional cleaner to remove dust, debris, and oxide. Apply a small amount of high-temperature resistant lubricant (recommended by Nanjing Zhuye Elevatorparts) to the lock’s moving parts to ensure flexible operation. Avoid lubricant contamination on Touch Point 161 to prevent poor contact.

Recommended Replacement Cycle for Elevator Door Lock MA630-05 (Touch Point 161)

As a core safety component bearing frequent mechanical locking/unlocking, Touch Point 161 contact wear, and environmental erosion (humidity, dust, vibration), the MA630-05 elevator door lock has a specified service life. Timely replacement is critical to avoiding faults such as loose locking, poor contact of Touch Point 161, contact burnout, or failure to unlock—issues that may lead to elevator operation with unlocked doors, failure to start, or even serious safety accidents.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily door opening/closing cycles ≥ 1500, environment temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for the Elevator Door Lock MA630-05 (Touch Point 161) is 4–5 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field data, door lock component aging tests, and global user feedback on elevator safety systems.

2. Adjustments for Special Scenarios

Harsh Environments & High-Traffic Scenarios: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or high-traffic areas (e.g., shopping malls, airports) with frequent door opening/closing (daily cycles ≥ 3000), the replacement cycle should be shortened to 2–3 years. Harsh conditions and frequent use accelerate lock body corrosion, Touch Point 161 wear, and wiring aging.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and clean, stable shaft environments, the replacement cycle can be extended to 5–6 years—only if Nanjing Zhuye’s professional inspection confirms the door lock’s locking force, Touch Point 161 conductivity, and mechanical structure are intact (consistent with original factory standards).

3. Immediate Replacement Conditions

Replace the Elevator Door Lock MA630-05 (Touch Point 161) immediately if any of the following issues occur, regardless of service life:

Touch Point 161 has poor contact or no contact (contact resistance > 100mΩ), leading to abnormal elevator operation (e.g., failure to start, false alarm) and the fault persists after cleaning and maintenance.
The door lock’s locking force is less than 100N, and the lock tongue cannot lock the door firmly, posing a risk of accidental door opening during elevator operation.
Touch Point 161 is severely worn, burned, or oxidized, and cannot be repaired; or the lock body is severely deformed, cracked, or corroded, affecting normal locking/unlocking.
The door lock fails the safety performance test (e.g., failure to disconnect Touch Point 161 when the door is unlocked, locking response time > 0.5s), failing to meet the elevator’s safety operation requirements.
