Quickly connect wires without crimping or twisting. When you press the clamp down, your wire is locked in and can’t be pulled out. Lift up the clamp to remove your wire. Because they're reusable, these connectors are great for temporary wiring during testing and prototyping. You can also use them to connect wires in an outlet box.

Clear connectors let you see that the wire is inserted properly and stripped to the correct length. They have two test slots—one on the front and one on the back—to test voltage even after the connectors are installed.

Use a DIN rail adapter (sold separately) to mount these connectors to a 35 mm DIN rail in a control cabinet.

Covers (sold separately) are lined with a sticky gel that seals water out. Unlike a potting compound, you don’t need to mix or pour the gel before you install these covers. They’re rated IP08, so you can use them in junction boxes exposed to rain, splashing, and humidity. If you have to expand or repair a circuit, you can open these covers and use the wires again. However, once you open the cover and remove the gel, you’ll need a new connector and cover.
