Ueda Seisakusho PU64W Series Pressure Switch

Manufacturer: Ueda Seisakusho Co., Ltd.
Model : PU64W series
Features
- The PU64W series is a waterproof pressure switch for outdoor use.
- The body cover is made of die-cast aluminum, and the weather-resistant neoprene packing ensures high sealing performance, so it can be used outdoors in rainy or humid environments.
- The two pointers on the scale plate allow you to see the set pressure at a glance, and the set pressure and opening/closing pressure difference (ON-OFF width) can be freely, quickly and easily adjusted with two adjustment screws.
