Our hazardous area limit switch box is designed to mount onto the top of pneumatic actuators to give position feedback. Four adjustable SPDT mechanical switches (two for open and two for closed) are wired into a terminal block. It also has termination for a solenoid valve so that a single multiple cable can be used. The solenoid can then be wired through the second conduit entry. The sight dome is colour coded for instant clarification of the valve position. Yellow for open and red for closed. Also available in 316 Stainless Steel upon request.
