Phoenix Contact PLC Push-In Technology Relays are equipped with push-in termination technology. Push-In Technology provides a fast, easy, safe connection and eliminates the need for insertion tools; even conductors as small as 22 AWG can be terminated. Terminations are made simply by pushing wires into the terminal, using very little force. To disconnect the wire, nearly any screwdriver can be used. Push-In Technology allows Phoenix Contact to meet the growing demand for the kinds of fast, safe, and error-free products now needed in industrial control cabinets. Phoenix Contact PLC Push-In Technology Relays, in 6mm housing, are 100% touch-proof and permit faster wiring - up to 50 % faster installation time.
