Design & Usage
These sensors are slim, cylindrical magnetic reed switches—often just a few centimeters in length—designed for easy integration into elevator mechanisms, shaft walls, or door frames. They detect magnetic fields (typically from onboard magnets) to indicate floor position, door closure, or safe-state conditions.
Key Specifications
Size: Varies, but commonly around 28–84 mm in length. jassalelevator.inliftotechequipments.inAajjo
Voltage / Power Ratings: Typical variants support up to 220–230 V, with current capacities ranging from a few hundred milliamps in compact plastic versions to several amps in robust models. jassalelevator.inAajjoliftotechequipments.in
Material & Protection: Often made of plastic (like PVC or ABS), sometimes featuring reverse-voltage protection, current ratings around 3 A, and power capacity around 120 W/VA. ExportersIndiaelevatorpartsvetal.comliftotechequipments.in
Function: Most are simple SPST (Normally Open or Normally Closed), but some advanced versions (like bistable models) are available for signaling persistent states. magnotechsensors.comshivangielevators.co.in
