EAO – Your Expert Partner for Human Machine Interfaces
Series 04 | with Push-In Terminals (PIT)
EAO, the Expert Partner for Human Machine Interfaces, is offering a new spring terminal connector technology for the popular Series 04 switch range. The Series 04 with PIT (push-in terminal), which features a spring terminal connection from Phoenix Contact, reduces assembly times by up to 70% when compared to screw terminals. It offers a more reliable, secure connection in combination with a very high resistance to vibration. Solid conductor wires with stripped ends, or stranded wires with bootlace ferrules can simply be pushed into the terminal, which opens automatically and then clamps down to firmly secure the wire in place. Stranded wires without ferrules, or thinner solid conductor wires can also be used. By pressing the orange lever with a 2 mm screwdriver the spring clamp is opened and the wires can be pushed in; releasing the lever secures the wires in place. The following products with push-in terminals have been added to the Series 04 range: ■■ Snap-action switch element (gold / silver): 10 products ■■ Slow-make switch element (gold / silver): 10 products ■■ Lamp block: 1 product Advantages of push-in terminals: ■■ Quick and easy wiring ■■ No special tools required ■■ Up to 70 % reduction in assembly time ■■ Permanent wire clamping at the correct pressure ■■ Vibration-resistant connection ■■ Two connection points per terminal ■■ IP20 “touch-proof connection” if wires are correctly stripped
