141R 2.54mm PCB Terminal Block

SUN is pleased to present 141R 2.54mm PCB Terminal Block. Spring terminal block connector is useful in applications using small wire diameters without the need for high strength connections as well as for use in a limited working space where screwing terminals down may be difficult. Depending on the model, the SUN 141R 2.54mm PCB terminal blocks are equipped with either one or two solder pins per position. The orange actuators make it easy for the person doing the wiring to recognize how to open the spring clamp.

The 141R 2.54mm PCB terminal block range now features a new highlight which considerably reduces the wiring required for power electronics. The PCB spring terminal block already has unlimited UL rating in a 15 mm pitch of up to 600 volts. Insulated bridges are available with a varying number of positions for looping through potentials and integrated test connections permit convenient use of test plugs. The PCB spring terminal block connector can also be screwed down with the aid of the lateral mounting flanges.
