7CX/7DX GO Switch
Brand: TopWorxGO Switch models 7CX (1.025" probe length) and 7DX (1.250" probe length) are hazardous area approved versions of our popular 7C and 7D Stroke-to-GO Hydraulic/Pneumatic End-of-Stroke Position Sensors.
The 7CX and 7DX probes and mounting flange are drop-in replacements to models 7C and 7D, respectively.
There is however a difference in the housing. Rather, than having a rotatable head, the wiring comes from the top of the unit and does not rotate.
Options for the 7CX and 7DX include a hermetic seal and various terminal options and lengths.
