Terminal Block For Sensor Wiring Offers Top-Entry Screw Clamps

The WK 2.5-4 KOI/U proximity terminal block allows for the wiring of multiple sensors powered by a single pair of power supply leads, saving time and labor costs. The 5-mm unit 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.Previously, similar products required that each sensor be wired with its own pair of power supply leads or connected to a series of multiple, bussed feedthrough terminal blocks, along with two connections for the signal feedthrough. The WK 2.5-4 performs all these functions, taking only a third of the DIN rail space in the process. The unit is rated for 300V and 20A and accepts wire sizes of 22 to 12 AWG.
