Noshock 400 Series Heavy Duty Mechanical Pressure Switch

With a stable switching point setting, the robust 400 Series Switch converts pneumatic and hydraulic pressure into switching functions, and is designed for applications requiring maximum accuracy under high loads. It is SPDT, and can be normally open (N.O.) or normally closed (N.C.) depending on the wiring. The switching point is fully adjustable by means of a simple adjustment knob within the adjustment range. It also includes a locking mechanism for switch point adjustment.

The 400 Series Switch is fitted with DIN EN 175301-803 Form A connectors for fast and easy installation. It is also available with an LED indicator on the plug for visual monitoring of the switch status, or an M12 x 1 (4-pin) electrical connection.
