Safety switch STA ASi, plug connector M12 (closed-circuit current principle)

  • Actuating head made of metal
  • Auxiliary release on the front

Guard locking type

STA3Closed-circuit current principle, guard locking by spring force. Release by control of AS-i output 0.

Control of the guard locking solenoid

The guard locking solenoid is controlled by the control system via AS-Interface bus bit D0. In addition, the 24V connection can be switched safely.

AS-Interface inputs

D0, D1Door monitoring contact SK
D2, D3Solenoid monitoring contact ÜK

Evaluation is performed via a safety monitor.

AS-Interface outputs

D1LED red
D2LED green

LED function display

  • The Power LED indicates the operating voltage on the bus.
  • The Fault LED indicates if a fault has been detected on the AS-Interface bus.
  • The green and the red LEDs can be controlled as required by the control system via the bus using bits D1 and D2.

Auxiliary release

This is used for releasing the guard locking with the aid of a tool. To protect against tampering, the auxiliary release is sealed with sealing lacquer.
