TX3C-A024MC2161 (Order no. 098946)

Safety switch TX, escape release

  • Auxiliary release on the front
  • Escape release on the rear side
  • Release under load possible
  • With door monitoring contact
TX3C-A024MC2161 (Order no. 098946)

Description

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Solenoid operating voltage

  • AC/DC 24 V +10%, -15%

LED function display

The switch has a function display (2 LEDs, red and green). The LED voltage is same as the solenoid operating voltage.

Guard locking type

TX3

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

Switching element

ETX C

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

Auxiliary release

This is used for releasing the guard locking with the aid of a tool. The auxiliary release must be sealed to prevent tampering (for example with sealing lacquer).

Escape release

This is used for manual release of guard locking from the danger zone without tools. With identification of On/Off position.
