Description

PCB terminal block, 257 Series, push-buttonQuick and easy connections are guaranteed with this PCB terminal block (item number 257-743/999-950). You can count on tried and tested safety with these PCB terminal blocks, perfect for a wide range of applications when designing your devices. Strip lengths must be between 5 and 6 mm  when connecting conductors to this PCB terminal block. Featuring one conductor terminal along with CAGE CLAMP®, this connector delivers reliable performance. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all types of conductors without having to prepare the conductor. For example, you don’t need to crimp ferrules. The item’s dimensions are (7.8 x 24.4 x 14.2) mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm².The contact surface is coated with tin. A push-button is used to operate this PCB terminal block. THT is used to assemble the PCB terminal block. The conductor is designed to be inserted at a 0° angle..
