Terminal Blocks - Wire to Board

Terminal blocks are widely used in today\'s industrial and commercial applications for the safe and reliable connection of electrical circuits. Marketed as “wire-to-board” connectors, or simply “terminal blocks”, terminals are designed to allow a connection point from a wire, either stranded or solid conductor, to a printed circuit board or panel. Typically, installation methods involve the use of screws, cage clamp, and the spring connection. While a few terminal block configurations are one-piece designs, most designs are made up of two pieces - a base which is mounted to the panel and an insulated, powered top section.

The 1874900000 Terminal Block

The 1874900000 terminal block by Weidmuller is a versatile solution for reliable connections in both commercial and industrial applications. The 1874900000 is a "connecting sleeve" type of terminal block, complete with quick-connect, single or double-level design, and a protective insulation.

It features a wide range of connection options: screw connection version with either metric/standard screws, push-in or cage-clamp connections, and for special applications, all-in-one spring connection. It can accommodate conductor sizes from 24 AWG to 8 AWG, for both stranded and solid wire. It’s available in 2, 4, 8 and 10-way housings, and is rated to 16A and 300V. The 1874900000 is UL recognized, CSA certified and meets IP20 rating.
