Push-in technology, presently used in products like terminal blocks and relay sockets, is now available in Harmony XB4 and XB5 22 range of 22 mm contact and indicator blocks to save installation time. Users only need to connect wires to the block installed behind the pushbutton head to make the connection. Because the wire is constantly in contact with the spring, there’s no need for tightening and no risk of vibrations from a running machine loosening the grip on the cable, which might be the case with screw blocks. Harmony XB4 and XB5 are also 37% thinner than spring clamps, making them easier to fit into tight spaces such as control stations. These compact, ergonomic, push-in blocks also feature faster, tool-free installation.
