The ATSTOP has a heavy duty tongue and head where the tongue allows a  +/- 12mm misalignment. The tongue and head unit can rotate in 90° increments. The product is ideally designed for machines without run down cycles where quick and frequent access to equipment is required, via either hinged or sliding doors.

When the machinery is in operation the tongue is engaged and the power is on. If accesss is required, the door is simply opened releasing the tongue from the unit,giving positively guided, forced disconnection of the safety switch contacts.
