Euchner CIS3P50X50SH16B Safety Interlock System

The Euchner CIS3P50X50SH16B Safety Interlock System is a safety device used to guard access to hazardous machinery by interlocking protective doors or gates. In typical use, opening the guard interrupts machine operation and prevents restart until the guard is securely closed, ensuring the guarding circuit enforces a safe state. The model CIS3P50X50SH16B identifies a specific configuration within Euchner’s CIS3 interlock family, indicating a predefined arrangement of housing, actuation interface, and contact configuration selected for guarding installations. This interlock system is designed for integration in industrial automation environments where access control to safety zones is required, helping to meet safeguarding standards by coordinating door status with the control system. When paired with a compatible safety controller and corresponding actuators, the CIS3P50X50SH16B forms part of a complete guarding solution that monitors guard position and enforces proper stop-and-restart behavior.
