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.
