Elevator Door Machine NO Bistable Magnetic Switch For Accurate Position Detection & Signal Feedback Part KCB-IIIA
- The KCB-IIIA is a normally open (NO) bistable magnetic switch specially designed for elevator door operator systems, which realizes state switching through magnetic trigger and is used for accurate position detection of door fully open and fully closed status.
- Adopting non-contact magnetic induction principle with built-in high-reliability reed switch element, it can maintain stable switching state without continuous power supply, featuring strong anti-electromagnetic interference performance for complex elevator hoistway environments.
- It supports a rated voltage of 250V AC/DC with a switching capacity of up to 120VA/W, delivering stable contact performance and long mechanical service life under frequent door opening and closing operation cycles.

- Constructed with flame-retardant and dust-proof engineering plastic housing, it adapts well to the narrow installation space of elevator door machines, with standard mounting holes for direct replacement of original same-model switches.
- With an effective detection distance of 5mm to 15mm and fast trigger response, it accurately feeds back real-time elevator door position, ensuring the elevator can only run after the door is fully locked in compliance with elevator safety standards.
- Each switch undergoes strict on-off performance and durability testing before delivery, widely compatible with various brands of elevator door systems, making it a common spare part for daily elevator door control system maintenance.
