Open feedback units are the most common standard and also the easiest way for the detection of most of the GEA Aseptomag valve types.

One or two (depending on valve stroke and amount of proximitiy switches) stainless steel brackets can be attached with screws to the pneumatic actuator. The proximity switches are be mounted by using the slot which is available in two different dimensions, once for M8 and once for M12 (standard) proximity switches. The power cables for this type of feedback is directly connected with the cabinet.
