Adjustable High Pressure Switches PCS8

Features

1 million mechanical life and high reliability

Short action time and high sensitivity

■ High pressure resistance and high safety

With metal shell design, the switch is more resistant to vibration and external impact 

 Pressure value can be adjusted

■ More shell types/pressure range/thread types/diaphragm types can be selected, which is suitable for more use occasions and has high adaptability


Applications

■ Construction machinery,such as excavators

■ Forklifttruck (oil burning type with hydraulic system)

■ Hydraulic system,such as hydraulic lubrication pump and hydraulic pump station
