Cost effective position monitoring for cylinders

Parker Hannifin’s mid stroke full pressure position switch `reads’ piston pressure through a steel cylinder body – allowing hydraulic cylinders with position sensing to be used at full rated pressure.

Repeatability is typically within 0.5mm, and the switches can provide safety interlocks in critical applications. Integral LEDs provide continuous visual monitoring. Also, the switching point of the mid stroke switches can be adjusted on the machine by the user, permitting the same cylinder to be adapted to suit different production processes. switches employ a sensor clamped to the cylinder tube, and magnets attached to the piston. The flux of these permanent magnets, as they pass the sensor, induces a temporary change of polarity in the sensor, and this change of polarity provides the switching effect.
