Gripping and swivel modules
Universal magnetic switch with ATEX certification
Schunk now offers a freely programmable and therefore universally applicable magnetic switch with ATEX certification for device group II, category 2, for querying gripping systems in potentially explosive atmospheres.
The MMS 22-PI1-EX has a freely programmable switching point and detects a magnet inside the actuator. It can be placed directly in the C-slot of the gripping or swivel modules without interfering contours. Instead of laboriously setting the switching point mechanically, the magnetic sensor can be programmed in just a few simple steps. The magnetic teach tool required for this is included in the scope of delivery. A plug teach tool is also available as an option. The respective switching status is signaled via an LED display. Thanks to the standard plug connector, the sensor can be easily connected using standardized connection cables.
Reliable scanning with small strokes
The adjustable hysteresis of the sensor enables reliable position detection even with very small strokes. This allows the entire gripping process to be better evaluated and controlled. The sensor can also be used to differentiate between workpieces of different sizes. The MMS 22-PI1-EX is suitable for the ATEX-compliant PGN-plus two-finger parallel gripper, the PZN-plus three-finger centric gripper and the SRU-plus universal swivel unit. It can also be used on the sealed two-finger parallel grippers DPG-plus and the sealed three-finger centric grippers DPZ-plus. The components are suitable for use in potentially explosive gas atmospheres (equipment group II, category 2), and the sealed grippers are also suitable for use in potentially explosive dust atmospheres (equipment group II, category 2).
The ATEX-compliant premium grippers and swivel units from Schunk comply with the ATEX Product Directive 2014/34/EU. Users, system integrators and plant manufacturers save on costly special solutions with the powerful and reliable modules and simplify the ATEX certification of their systems. The ATEX components can be used wherever there is an increased risk of explosion due to gases or dusts. This includes, for example, the machining of solids, painting systems, processes in surface technology, foundries, mining operations and even mills or bakeries where sacks of flour are handled. The specially surface-treated ATEX modules are just as efficient as their original components. They therefore open up potential for automation in potentially explosive environments. as
