Details of the P8S-A34X

The P8S-A34X Pneumatic Cylinder Sensor for P1F-T and P1D-T cylinders provides an ideal solution where a direct pneumatic signal is wanted from a cylinder sensor to a pneumatic control system. This could be a machine or device in which only compressed air is available and an electricity supply to normal cylinder sensors would involve serious problems or considerable expense.

The function of non contacting sensing of a pneumatic cylinder, triggering an output signal (conn 2) from the integrated 3/2 NC valve, which is activated by a magnetic field or iron core and has a return spring. If more than one sensor is used with a cylinder there must be a distance of at least 20mm between sensors to prevent them influencing each other. To avoid interference ther must be a minimum spacing of 15mm to steel details. The outlet (conn 3) must be blocked or restricted as this can impair the function of the sensor. The sensor is fastened to the cylinder using the special sensor bracket P8S-AMA1.
