STA4A-4141A024M (Order no. 109172)

Description

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Solenoid operating voltage

  • AC/DC 24 V +10%, -15%

Guard locking type

STA4

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