Note: Unless otherwise specified, a tolerance of

±0.4 mm applies to all dimensions.

*1. The usable range for stainless steel wires and resin rods is 35 mm max. from the end with a total travel of 70 mm max.

*2. In terms of construction, the Switch is a General-purpose Limit Switch rather than a Safety Limit Switch.

Slow-action (1NC/1NO) (2NC/1NO) (2NC) (3NC)

Note: Variation occurs in the simultaneity of contact opening/closing

operations of 2NC, 2NC/1NO, and 3NC contacts. Check

contact operation.
