91MCE Series Limit Switch
Honeywell’s new 91MCE Series limit switch is an addition to the
existing CE Series limit switches. 91MCE is cost-effective sensing
components with factory pre-wiring or M12 quick connector which
allows for miniaturization of connection and eliminates the need to
wire at the switch. This allow 91MCE to be used in limited access
areas. A full range of actuators and wiring options are available.
91MCE available in snap action and slow action with direct
opening feature. Zinc die cast housing and epoxy potting allow the
switch to be used in harsh environment.
