Description

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Solenoid operating voltage

  • AC/DC 24 V +10%, -15%

LED function display

A function display (2 LEDs, red and green) is available for the following voltage ranges:

  • AC/DC 24 V +10%, -15%

Guard locking type

STA3

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