Elevator Limit Switch JY-1370-A & JY-1371-I: Reliable Safety Components from Nanjing Zhuye Elevatorparts
The Elevator Limit Switch JY-1370-A and JY-1371-I are two high-performance electromechanical safety components specially designed for elevator overtravel protection, mainly used to detect the position of elevator cars at upper and lower terminal stations, trigger circuit on-off through mechanical collision, and prevent elevator overtravel to ensure the safety of passengers and equipment. As core safety components supplied by Nanjing Zhuye Elevatorparts, these two limit switches fully comply with international standards such as EN ISO 13849-1 and EN IEC 60947-5-1, as well as national safety regulations for elevators, with stable performance and strong adaptability to harsh elevator hoistway environments. They feature 1NO/1NC contact configuration, IP65 protection grade (effectively preventing dust and water splashing according to IP rating standards), double insulation design, and flame-retardant engineering plastic enclosures, widely compatible with mainstream elevator brands including Kone, Otis, Mitsubishi, Schindler and domestic well-known brands, applicable to residential buildings, commercial complexes, hospitals and public facilities.
Nanjing Zhuye Elevatorparts adheres to stringent quality control standards, and the JY-1370-A and JY-1371-I elevator limit switches are prime reflections of this commitment. Each switch undergoes rigorous pre-delivery testing, including mechanical life testing (minimum 10,000,000 operations), high-low temperature (-25℃ to 85℃) resistance tests, insulation performance verification (≥2MΩ with 500V megohmmeter), and contact reliability detection. Both adopt adjustable roller lever actuators that can be repositioned by 4×90°, M20×1.5 screw terminals for wiring (supporting cable sections ranging from 0.75mm² to 2.5mm²), ensuring stable installation and signal transmission. Their compact structure and lightweight design make them easy to install in narrow elevator hoistway spaces, and they are backed by a standard one-year warranty from Nanjing Zhuye Elevatorparts.
Usage Guide for Elevator Limit Switch JY-1370-A & JY-1371-I
As key safety components for elevator operation, the JY-1370-A and JY-1371-I limit switches require proper installation, debugging and daily inspection to ensure elevator safety. Nanjing Zhuye Elevatorparts strongly recommends that all operations be performed by certified elevator maintenance technicians to avoid safety hazards caused by improper operation. Before installation, confirm that the switch models (JY-1370-A/JY-1371-I) match the elevator’s terminal station control system. For detailed installation dimensions, wiring diagrams and contact configuration parameters, refer to the product manual provided by Nanjing Zhuye Elevatorparts or contact our professional technical support team.
1. Pre-Installation Preparation
First, cut off the elevator’s main power supply and lock the switch to prevent accidental startup, then move the car to the upper or lower terminal station to ensure a safe operation space. Prepare professional tools: screwdriver, torque wrench, wire strippers, insulation tape, multimeter and level ruler, referring to standard installation tool preparation specifications for electrical components. Clean the installation position in the elevator hoistway (upper and lower terminal station guide rail brackets) to remove dust, oil stains and rust that may affect installation accuracy—similar to the pre-installation cleaning requirements for elevator electrical components. Carefully inspect the JY-1370-A/JY-1371-I switch for external damage, such as cracked enclosure, loose terminals or damaged roller lever. Use a multimeter to test the contact continuity (NO contact is open when not actuated, NC contact is closed) to ensure no internal faults.
2. Installation & Wiring
Fix the JY-1370-A/JY-1371-I switch on the pre-installed bracket according to EN 50047 mounting standards, adjust the position with a level ruler to ensure the roller lever is aligned with the elevator car’s collision block, and the actuating angle is adjusted to 30-60° to ensure sensitive triggering. Tighten the fixing screws according to the specified torque to prevent loosening caused by elevator vibration. Follow Nanjing Zhuye Elevatorparts’ wiring guidelines to connect the switch’s terminals to the elevator control cabinet: connect the power and signal wires to the M20×1.5 screw terminals (referring to standard terminal wiring principles for electrical components), ensure firm connection, and wrap the joint with insulation tape to prevent short circuit. Separate power wires and signal wires to reduce electromagnetic interference, and confirm the contact configuration (1NO/1NC) matches the control system requirements before completing wiring.
3. Debugging & Daily Inspection
After installation and wiring, restore the elevator’s main power supply and start debugging. Operate the elevator in maintenance mode to run to the upper and lower terminal stations, verify that the roller lever is smoothly actuated when touched by the car’s collision block, the switch contacts are reliably switched, and the elevator stops accurately at the set position without overtravel. For daily inspection, follow TSG T7001-2023 and TSG T5002—2017 regulations: Check the switch’s enclosure, terminals and roller lever monthly for damage or loosening; use a multimeter to test contact continuity quarterly. Clean the roller lever and contacts regularly to remove dust and oil stains, ensuring sensitive actuation and reliable signal transmission, which is crucial for maintaining long-term stable operation.
Replacement Cycle of Elevator Limit Switch JY-1370-A & JY-1371-I
The replacement cycle of the JY-1370-A and JY-1371-I limit switches depends on usage frequency, operating environment and maintenance quality, referring to their mechanical life and industry safety standards. Under normal conditions—12-24 hours daily operation, regular inspection, and a dry, clean hoistway environment—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 4-6 years. This cycle fully considers contact wear, enclosure aging and actuator performance degradation during long-term use.
For elevators in high-traffic areas (airports, subway stations) or harsh environments (high humidity, heavy dust, oil pollution), the replacement cycle should be shortened to 2-4 years. Harsh environments easily cause enclosure corrosion and poor contact (especially affecting the IP65 protection performance), while high-frequency actuation accelerates roller lever wear. For low-usage elevators (villas, small offices), proper daily inspection can extend the replacement cycle to 6-8 years. However, switches used for more than 5 years require semi-annual comprehensive inspections by Nanjing Zhuye Elevatorparts technicians to assess replacement needs in advance.
Replace immediately if: The switch fails to actuate or contact reliably; the enclosure is cracked or severely corroded, reducing the protection grade below IP65; contact bounce exceeds the standard; the roller lever is worn or stuck; the switch causes frequent elevator terminal station stop faults; it fails to pass the annual elevator safety inspection. Use 100% genuine JY-1370-A and JY-1371-I switches from Nanjing Zhuye Elevatorparts to ensure compatibility and elevator operation safety.
