MICRO SWITCH Miniature Safety Switches 004787 24CE Series Issue 1 Datasheet FEATURES Compact metal housing epoxy encapsulated with the common 25,4 mm 1.0 in center-to-center mounting Positive opening operation of normally closed contacts to EN/IEC 60947-5-1-3 specification Designed and agency evaluated for safety functions up to a SIL3 level Three different slow-action circuit options: 1NC/1NO BBM (break-before-make), 1NC/1NO MBB (make-before-break), and 1NC Wide range of actuator heads and levers Can be gang mounted for multiple-pole capability CE approvals Environmentally sealed to IP66 DESCRIPTION Standard temperature operating range of 0 C to 70 C Honeywells 24CE Series of miniature electromechanical safety 32 F to 158 F switches are designed with a rugged metal housing. This Series Optional low temperature operating range of -40 C to 70 C features positive opening normally closed contacts to -40 F to 158 F EN/IEC 60947-5-1-3 specifications. Due to their small size and positive opening normally closed contact, the 24CE Series POTENTIAL APPLICATIONS provides a safety solution for applications where the size of other Industrial products could be prohibitive on the machinery. The 24CE Series - Machine tools (small doors and apertures) offers a variety of configurations which include a wide range of - Material handling actuators, and circuits to solve many application issues. These - Packaging machinery miniature switches are weather sealed to IP66 for demanding - Trailer/truck restraint systems (dok-loks) environments on indoor or outdoor machinery. In addition, Transportation the 24CE Series has been evaluated for safety functions up - Small construction machinery to a safety integrity level (SIL) of SIL3 when evaluated to the requirements of IEC 61508-2:2010. PORTFOLIO MICRO SWITCH 24CE Series miniature safety switches VALUE TO CUSTOMERS complement the 924CE Series of miniature safety limit switches. Miniature rugged 24CE switches with common 25,4 mm These Series of switches are a small segment of the total family 1.0 in mounting footprint of Honeywells MICRO SWITCH electromechanical safety Switches easily gang mounted for multi-pole capability switches. Low temperature option of -40 C -40 F Long life of up to 10 million mechanical operations DIFFERENTIATION Miniature metal body size of 40 mm L x 16 mm W x 49 mm H 1.58 in L x 0.63 in W x 1.93 in H requires less space on machinery Positive opening normally closed contacts with an optional normally open contact Designed and evaluated for safety functions up to a SIL3 level Sensing and Productivity SolutionsMICRO SWITCH Miniature Safety Switches, 24CE Series Table 1.
