Contact Block Technical Data

Type Contacts Action Forced Disconnect Voltage (max.) Current (max.)

U1Z 1 N.C. 1 N.O. Slow Yes 250 VAC 10 ASU1Z 1 N.C. 1 N.O. Snap Yes 250 VAC 10 A

Notes:1. All Contact Blocks Break-Before-Make2. Normally Closed Contacts Forced Disconnect per IEC 947-5-1 Ch.3 (As Indicated)

Contact Block Wiring DetailsU1Z - Slow Make-and-Break SU1Z Snap Action

Types of Contact Block and Action Linear Type Rotary TypeActuator Lever

U1Z Break-Before-Make theNC contact opens beforethe NO contact closes

SU1 Snap action arrowindicates direction of travel

11-12, 21-22, 23-24 Indicates terminal identification for wiring.Operating force shown in Newtons. Newtons x .2248 = lbs.Graduation Tolerance + 3.5Accuracy of switching point + .009Tolerance of switching pressure + 10%

Switching Action ExplanationSlow Action

Used in precision applications for switching on and off at the exact point

Contact closes at the same speed as actuator/leverSnap Action Used when good solid contact is required

Used with inductive loads to prevent arcing
