Ismertetés

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Additional Bi-state function

In addition, the STP-BI has a function to prevent

  • persons from unintentionally locking themselves inside if the safety door is open in case of a power failure or if the machine is switched off
  • the deactivation of the activated guard locking in case of a power failure.

Solenoid operating voltage

  • AC/DC 24 V +10%, -15%

Guard locking type

STP3

Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid.

Switching element

2131

Slow-action switching contact 2 NC + 1 NO + 1 NC (door monitoring contact)

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.
