91MCE Series
Mini Compact Limit Switch
DESCRIPTION
The 91MCE series limit switch is a compliment to Honeywell's
existing product line of smaller, lower cost limit switches.
Designed for modern industrial OEMs, the miniature package
size fits in applications where space is limited. The small
package size can be gang mounted for applications requiring
more than two switch circuits. The 20mm mounting pattern
meets most globally accepted mounting standards.
This product family offers the user many options including a
variety of different actuator styles. Connection options include
pre-leaded cable in various lengths or M12 connectors, both
with side or bottom exits. Design flexibility is further enhanced
with the availability of both slow action and snap action
circuitry. Direct acting contacts are designed to open the NC
contact when actuated. The epoxy-sealed rugged die-cast
housing provides enhanced environmental durability.
Priced competitively, the 91MCE is a drop-in replacement to
many products, and provides enhanced quality that customers
expect from Honeywell.
