Bernstein Door Contact SEL1/2-A1Z for Selcom Door

Electrical Limit Contact for Elevator Door Systems

Product Description

The Bernstein Door Contact SEL1/2-A1Z for Selcom door is an electrical switching component used to provide position feedback within elevator door systems. It is typically installed where a defined mechanical movement triggers the contact, allowing the system to detect door status during operation.

As part of the door control circuit, this type of contact helps transmit switching signals when the door reaches a specific position. Reliable signal feedback is important for maintaining correct door sequence and safe elevator operation.

Because door systems perform repeated opening and closing cycles every day, electrical contacts may wear over time due to frequent triggering and long-term service use. Replacing a worn contact can help restore stable signal response and reduce interruption caused by inconsistent switching performance.
