Yale YB37-12D-LR Electric Strike 12V DC Fail-Safe with Monitoring Micro-Switch

Product Overview

Yale YB37-12D-LR is a fail-safe electric strike designed for access control systems using 12V DC power. It enables door unlocking when power is cut, supporting secure egress during power outages or emergencies. The unit features a flat, extended mounting plate for versatile installation on metal, aluminium, PVC, and wooden doors, as well as gates. Equipped with a monitoring micro-switch, it provides status feedback for integration with security systems.

The integrated monitoring function via a micro-switch distinctly separates this SKU from standard electric strikes. This feature eliminates ambiguity in door state tracking, reducing security risks and facilitating compliance in applications requiring real-time access logging. Particularly suited for specification-driven projects, B2B buyers managing office, industrial, or residential access infrastructure will find it ideal for installations where state monitoring and fail-safe operation are critical.
