ApplicationSafety interlock switches with separate actuator are used where the position of doors, cov-ers or safety screens must be

monitored for safety reasons. For example, they can be used together with 3TK28 safety re-lays up to safety category 4.

ConstructionInterlock switches with separate actuator are available in three versions.• Molded plastic enclosure with

mounting dimensions accord-ing to EN 50 047

• Metal enclosure with mounting dimensions according to EN 50 041

• Molded plastic enclosure out-side of the standards that have arisen in this form in accor-dance with general market re-quirements.

When used as a safety switch mounting at a spacing of 20 mm (molded plastic housings) or 30 mm (metal housing) is neces-sary. Or, the interlock switch must be fitted with a pin or stop.

OperationInterlock switches with separate actuator can only be operated with a matching triple-coded ac-tuator. Actuation by hand or with auxiliary devices is virtually im-possible.The actuators are not included with the interlock switch and must be ordered separately.

Side operating heads can be ro-tated in 90° increments and can-not be replaced with actuators of the standard type.Operating heads for the 3SE2 243 and 3SE2 257 types cannot be changed.

Radius actuatorInterlock switches with radius actuators are particularly suit-able for rotatable protection de-vices. The movable actuation key allows even small radii to be approached. Damage to the switch and the actuator due to inaccurate approach is pre-vented.

Contact reliabilityThe movable contacts of the 3SE2 120, 3SE3 170 and 3SE2 200 switches are designed as double-break contacts. This en-sures extremely high contact stability, even when the devices are switching low voltages and currents, e.g. DC 5V / 1 mA.
