Sensor junction boxes distribute power and data between one control system and several devices like sensors and actuators. Also known as passive wiring blocks, they have threaded input and output receptacles that support circular connectors and prevent accidental disconnect. They plug and unplug without tools, and are ideal for industrial and automated applications that require maintenance or diagnostics, such as robotics, machine tools, and hydraulic machinery. Mounting holes allow them to secure on surfaces and machinery to help absorb vibration and shock.
