• Direct connection to the worm wheel [hardly any backlash]

• Contact less end position sensors [hall sensors]

• Modular design - can easily be adapted to different gearbox sizes

• Can be positioned at every 90°

• Continuous mechanical position indication

• Generation of a end position signal for swivel movements between 80° and 100°
