Terminal Blocks Offer More Possibilities

Terminal blocks that can be plugged in both horizontally, as well as vertically, offer developers a high degree of flexibility. This is the advantage of the 3857 series (cable-side) and 3867 (PCB-side) of the WR-TBL terminal block series from Würth Elektronik. The male connector on the PCB allows the mating connector to be plugged-in with either a 90° or a 180° cable outlet. Rather than having to revert to a new component, you just turn the existing one around and save valuable time. And to make assembly even quicker, the terminal blocks are available from 2 to 18 poles as standard and are extremely easy to separate to a smaller number of poles using a conventional cutter knife.

With a pitch of 5.0 mm, the pluggable version of the WR-TBL series allows connection of cable cross-sections from 24 to 12 AWG (0.205 to 3.32 mm²). Moreover, they distinguish themselves with a current carrying capacity of 14A (UL) and 16A (VDE) and a working voltage of 300 VAC (as per UL) and 250 VAC (VDE) respectively. Another specific feature is the solid contacts that also predestine the terminal blocks for development.
