Introduction

Honeywell's 924CE series miniature electromechanical safety switches feature a robust metal housing design. The series incorporates forced-open normally-closed contacts compliant with EN/IEC 60947-5-1-3 specifications. Due to their compact size and forced-open normally-closed contacts, the 924CE series provides a safety solution for applications where other product sizes may impose mechanical constraints.

The 924CE series offers multiple configurations, including a variety of actuators, circuits, and electrical terminations to address numerous application requirements. These miniature switches achieve IP66 environmental sealing in harsh indoor or outdoor machinery environments. Furthermore, when evaluated in accordance with IEC 61508-2:2010, the safety function of the 924CE series has been assessed to SIL3 of the Safety Integrity Level (SIL).
