With wiring systems in the protection IP65/67/69K is realised in the field level an economical & rational wiring of sensors & actuators The Phoenix Contact Sensor / Actuator boxes make their decisive role. Instead of many individual lines has been transferred from the Sensor / control unit for a strain cable & connect the sensors & actuators locally. Main cable is appropriate & contained already as hybrid cables voltage supply & the control lines for the sensors or actuators. Distributors are available with 4.6 or 8 slots. Maximum 16 sensors or actuators are attached to the double-occupied box.
