MICRO SWITCH™ Miniature Safety Switches

24CE Series

DESCRIPTION

Honeywell’s 24CE Series of miniature electromechanical safety

switches are designed with a rugged metal housing. This Series

features positive opening normally closed contacts to

EN/IEC 60947-5-1-3 speciﬁcations. Due to their small size and

positive opening normally closed contact, the 24CE Series

provides a safety solution for applications where the size of other

products could be prohibitive on the machinery. The 24CE Series

offers a variety of conﬁgurations which include a wide range of

actuators, and circuits to solve many application issues. These

miniature switches are weather sealed to IP66 for demanding

environments on indoor or outdoor machinery. In addition,

the 24CE Series has been evaluated for safety functions up

to a safety integrity level (SIL) of SIL3 when evaluated to the

requirements of IEC 61508-2:2010.

VALUE TO CUSTOMERS

• Miniature rugged 24CE switches with common 25,4 mm

[1.0 in] mounting footprint

• Switches easily gang mounted for multi-pole capability

• 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

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

• Standard temperature operating range of 0 °C to 70 °C

[32 °F to 158 °F]

• Optional low temperature operating range of -40 °C to 70 °C

[-40 °F to 158 °F]

POTENTIAL APPLICATIONS

• Industrial

- Machine tools (small doors and apertures)

- Material handling

- Packaging machinery

- Trailer/truck restraint systems (dok-loks)

• Transportation

- Small construction machinery

MICRO SWITCH™ Miniature Safety Switches, 24CE Series GANG-MOUNT CAPABILITY MOUNTING The 24CE Series housing has been designed to enable the user to build their own multiple plunger switch by gang mounting several switches. All pin plunger and roller plunger types are suitable for gang mounting. There is a 16 mm distance between the plungers. The Series is very versatile such that even a levertype version could be added at the end of the row.
