The TopWorx GO™ Switch Model 7J integrates a rugged proximity limit switch and junction box into one compact device, simplifying wiring and delivering reliable position sensing in hazardous and space-constrained industrial environments.
The 7J is a one-piece proximity sensor and junction box assembly that allows the end-user to terminate directly to the sensor, reducing rewiring time. There is no need to acquire a separate fitting and junction box to be able to terminate to the sensor. The compact design gives the user the ability to install the sensor in areas where there are space constraints or where precision sensing is required, i.e., short-stroking valves. The product is available with NEC and IEC hazardous area classifications and is available with imperial or metric threads.
