The safety switches with tumbler are exceptional safety-related devices which prevent an unforeseen or intentional opening of protective doors, protective grilles or other covers as long as a dangerous situation is present (i. e. follow-on motion of the switched-off machine).

The safety switches with solenoid interlocking are comprised of a switch part with electromechanical interlock and a mechanical actuator which has to be ordered separately.

They are rugged protective devices that enable the greatest possible safety for man and machine.

The safety switches with solenoid interlocking are offered in plastic or metal enclosures.

Dimensions (W Г— H Г— D): 54 mm Г— 185 mm Г— 43.5 mm

Actuation

The actuator head is included in the scope of supply. For actuation from four directions it can be adjusted through 4 Г— 90°. The switches can also be approached from above.

The actuators are not included in the scope of supply of the safety switch and must be ordered separately from a choice of different versions to suit the application see Accessories.

Actuation data:

• Maximum actuating speed v_max = 1.5 m/s
• Minimum actuating speed v_min = 0.4 mm/s
• Minimum force in the direction of actuation F_min = 30 N

The actuator is encoded. Simple overruling by hand or auxiliary devices is impossible.

Radius actuators

The safety switches with radius actuators are particularly suitable for rotary protective devices. The movable actuation key allows even small radii to be approached. Damage to the switch and the actuator due to inaccurate approach is prevented.

Locking devices

A high-grade steel locking device for attaching up to eight padlocks is available for even more security, see Accessories.

Dust protection

For use in dusty environments, a rubber cap is offered that protects the actuator entries of the actuator head from dirt, see Accessories.

Tumbler

There are two versions for interlocking the actuator:

• Spring-actuated lock (closed-circuit principle) with various release mechanisms
• Solenoid-locked (open-circuit principle)

The spring-actuated lock switch is equipped with an auxiliary release for emergency situations or setup mode. Available as options:

• Escape release or
• Emergency release

Contact blocks

The safety switches with solenoid interlocking have one switching block each for:

• Monitoring the actuator or the position of the protective door
• Monitoring the position of the solenoid

The mechanical design of the switches corresponds to the requirements of the fail-safe principle according to EN ISO 14119.

Optical signaling equipment

The safety switches with solenoid interlocking are available with an optional optical signaling device.

The signaling device indicates the switch position of the interlock and the protective device optically by means of 2 LEDs on the front.

Protective device	Tumbler	Display	Meaning
Closed	Released	+	Actuator to be pulled
Closed	Locked		Actuator locked
Open	Released		Actuator pulled

Internal wiring:

• The yellow LED is pre-wired to the magnetic monitoring NO contact.
• The green LED is pre-wired to the actuator monitoring NC contact.
• LED ground is pre-wired with the ground of the solenoid.

Note:

• The operational voltage must be connected to the corresponding contacts by the customer.
• This voltage for the LEDs must match the operational voltage of the solenoid (same potential).
