Ueda Seisakusho P5S Series Pressure Switch

Manufacturer: Ueda Seisakusho Co., Ltd.
Model : P5S series

Features

The P5S series is a general-purpose pressure switch that is widely used as an automatic control device for hydraulic, pneumatic, water and liquid pressure in machine tools, industrial machinery, chemical plants, power plants, etc.
The snap action mechanism makes this a highly reliable pressure switch with a long life.
Pressure adjustment can also be made from the outside without removing the body cover, and indicators for the upper limit pressure setting and the opening and closing pressure difference are provided so that the upper limit pressure and the upper limit pressure setting can be seen at a glance, allowing for quick and easy readjustment on site.
