ENTRELEC SNK PI-Spring Terminal Blocks

TE Connectivity's (TE) ENTRELEC SNK PI-Spring Terminal Blocks can be used as a push-in or traditional spring connection. Push-in mode allows direct one-step insertion of solid flexible standard wires with a ferrule, which is 50% faster than standard screw clamp technology. Using the spring mode, a screwdriver easily opens the spring clamp for wire insertion with no ferrule required. The screwdriver locks in the terminal block after insertion. TE ENTRELEC SNK PI-Spring Terminal Blocks offer a 20% larger marking area improving circuit identification and an asymmetrical design allowing an immediate visual check in case of reversed terminal blocks. Connection capacity ranges from 0.2mm² to 25mm² (26AWG to 4AWG).
