Description
PCB terminal block, 257 Series, angled push-buttonThis PCB terminal block (item number 257-843/999-950) is designed for quick and simple connections. You can count on proven safety with these PCB terminal blocks, perfect for a host of applications when designing your devices. Conductors can only be connected to this PCB terminal block if their strip length is between 5 and 6 mm . 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 dimensions are (7.8 x 24.2 x 14.2) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is designed for conductor cross sections ranging from 0.08 mm² to 2.5 mm².Tin is used for coating the contact surfaces. Push-button (angled) is used to operate this PCB terminal block. THT is used to solder the PCB terminal block. The conductor is designed to be inserted at a 0° angle..
