The BS20 Series, manufactured by MM Engineering, is a series of fixing clips generally designed for the attachment of magnetic field sensors to the suction lifter. This clip is fixed in the proper position through means of two locating pins on the clip, which fit into two grooves on the suction filter. In order to secure the locking, the M3 screw must be tightened.
The fixing clip is positioned together with the sensor so that the magnetic field sensor is actuated in the upper end position of the piston.
