Elevator Limit Switch JY-236-SA8-11C & JY-236-SA8-11T: Reliable Safety Components from Nanjing Zhuye Elevatorparts
The Elevator Limit Switch JY-236-SA8-11C and JY-236-SA8-11T are two high-reliability safety components specially designed for elevator operation protection, mainly used to control the stop position of elevators at upper and lower terminal stations, prevent overtravel, and provide a critical safety barrier for elevator operation. 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, with consistent performance and strong environmental adaptability. They feature 1NO/1NC contact configuration, IP65 protection grade, double insulation, and glass-fiber reinforced thermoplastic enclosures resistant to oil and corrosion, widely compatible with mainstream elevator brands including Kone, Otis, Mitsubishi, Schindler, and domestic well-known brands.
Nanjing Zhuye Elevatorparts adheres to stringent quality control standards, and the JY-236-SA8-11C and JY-236-SA8-11T elevator limit switches are prime reflections of this commitment. Each switch undergoes rigorous pre-delivery testing, including mechanical life testing (minimum 15,000,000 operations), high-low temperature (-25℃ to 85℃) resistance tests, insulation performance verification, and contact reliability detection. Both adopt angle roller lever actuators that can be repositioned by 4×90°, M20×1.5 screw terminals for wiring, and support cable sections ranging from 0.75mm² to 2.5mm², ensuring stable installation and signal transmission. Their compact size and lightweight design make them easy to install in narrow elevator hoistway spaces, backed by a standard one-year warranty.
Usage Guide for Elevator Limit Switch JY-236-SA8-11C & JY-236-SA8-11T
The JY-236-SA8-11C and JY-236-SA8-11T limit switches are key safety components of elevators, so proper installation, debugging, and daily inspection are crucial to ensure elevator operation 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-236-SA8-11C/JY-236-SA8-11T) 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. 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. Carefully inspect the JY-236-SA8-11C/JY-236-SA8-11T 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-236-SA8-11C/JY-236-SA8-11T 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 30° to the switch axis. 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 wire (0.75-2.5mm²) to the screw terminals, ensure firm connection, and wrap the joint with insulation tape to prevent short circuit. Separate the signal wire from the power wire 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 the car’s collision block touches it, the switch contacts are reliably switched, and the elevator stops accurately at the set position without overtravel. Test the switch’s response speed (actuating speed 300mm/min to 1m/s) to ensure it meets the safety standard. For daily inspection, follow 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.
Replacement Cycle of Elevator Limit Switch JY-236-SA8-11C & JY-236-SA8-11T
The replacement cycle of the JY-236-SA8-11C and JY-236-SA8-11T limit switches depends on usage frequency, operating environment, and maintenance quality, referring to their mechanical life (15,000,000 operations) 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, 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 protection grade; 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-236-SA8-11C and JY-236-SA8-11T switches from Nanjing Zhuye Elevatorparts to ensure compatibility and elevator operation safety.
