This proximity terminal block is said to allow for the wiring of multiple sensors powered by a single pair of power-supply leads. Designated the WK 2.5-4 KOI/U, the 5.0 mm terminal block reportedly provides simplified wiring with easy-access top connections, vertical-entry clamping bodies for sensor leads and a screw head also accessed in the vertical plane. Its low profile, as compared with multitiered side-entry blocks, makes it suitable for use in shallow cabinets. With four terminals per block (two for supply and two for signal lines), it is rated for 300 V and 20 A.
