I am looking for a cam operated limit switch to pilot another valve. the switch will be used on the outside of a vehicle in -40 degrees C. I have found a few that would work but they only go down to 0 degrees C
You may try ARO (as Ray said) or you can try Mead they both make this style valve. However for mobile applications like you have, you want to use a valve which has a rubber boot over the actuator. You will destroy most valves in this application
I need a pneumatic limit switch also. It will need to sense the proximity of an air spring and has to operate in an explosion-ready environment safely. The solenoid operated type would be great, but specifications require pneumatic operation only.
