Terminal Blocks for RTD and Thermocouple Connection Heads


Oblong	Round

These terminal blocks fit inside connection heads for thermocouples and RTD. Make sure the block has enough circuits for your probe, and use a wire that matches your probe type. You can insert stripped wire directly or attach a terminal to prevent damage from the fastener.

Quick-Connect Modular DIN-Rail Mount Terminal Blocks

Pop wire in and out of these terminal blocks without adjusting a screw. Lift the clamp with a screwdriver or built-in lever, then release the clamp down onto the wire. Once clamped in place, the wire will stay put when vibrated, bent, or pulled.

Mix and match these terminal blocks to get the exact number of circuits you need in a single setup. Add blocks for thermocouples, fuses, and grounding wire as needed. The blocks clip side by side onto DIN rail in control panels, creating tidy rows of circuits that you can identify and access on the spot.

Terminal Blocks with Spring-Clamp Terminals

Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Adjacent Jumpers—Metal poles create an electrical connection between adjacent terminal blocks, so you can connect multiple components with a single wire. Blocks must be the same width for the jumpers to fit.

Alternate Jumpers—Connect terminals on two blocks of the same width, skipping a block in between. This reduces wire clutter and gives you flexibility to adjust your set-up in the future.

Sensor Terminal Blocks with Spring-Clamp Terminals

These blocks connect sensors and actuators with NPN and PNP outputs. An LED indicates whether the circuits are powered, making it easier to troubleshoot your system. Mix and match blocks to consolidate wiring for multiple sensors, such as light and photoelectric sensors on a conveyor line. Other terminals on the blocks connect PLCs, data loggers, and other components.

For NPN Signal Output—These blocks light up when a connected NPN sensor sends a negative signal. They're common in Asian automation systems.

For PNP Signal Output—These blocks light up when a connected PNP sensor sends a positive signal. They're common in North American and European automation systems.

Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Modular DIN-Rail Mount Terminal Blocks

The screw-clamp terminals flatten your wire so it stays put when vibrated or pulled. If you need to change wiring frequently without adjusting a screw, consider a quick-connect terminal block with spring-clamp or lever-clamp terminals.

Terminal Blocks with Screw-Clamp Terminals

Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Bar Jumpers—Metal poles create an electrical connection between blocks, so you can connect multiple components with a single wire. Blocks must be the same width for the jumpers to fit. Cut jumpers to size with a hacksaw or high-force wire cutter. Add covers so jumpers don't touch the screws on the outermost blocks.

Insulation—Terminal blocks with insulated jumpers maintain their IP20 rating to prevent shocks and short circuits. Blocks with noninsulated jumpers lose their IP20 rating for touch protection because the jumpers introduce exposed metal to the circuit.

Fuse Terminal Blocks with Screw-Clamp Terminals

Install a fuse in the built-in fuse holder so excess current doesn't damage your equipment. If the current exceeds the limit, the fuse will blow and cut power to connected components.

Blown Fuse Indicator—A light goes on when the fuse blows, so you can spot an overloaded circuit without cutting power or touching equipment.

Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

Plug voltage meters into the built-in sockets to confirm the voltage is right for your application. You can also test and troubleshoot circuits without removing any wire. Push, turn, and release the knob to break your connection. When the knob is released, stick a wire through the hole so you can't accidentally reconnect the circuit—similar to a lockout tag.

Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Quick-Connect Plug-and-Socket Modular DIN-Rail Mount Terminal Blocks

Cut power with the pull of a plug when you need to swap out equipment or adjust your circuit. One of the openings on these blocks is a socket, so you can wire a plug outside the enclosure and then attach it to the socket that’s already in place.

The other connections are spring clamps, so you can pop wire in and out of these terminal blocks without adjusting a screw. Lift the clamp with a screwdriver, then release the clamp down onto the wire. Once clamped in place, the wire will stay put when vibrated, bent, or pulled.

Mix and match these terminal blocks to get the exact number of circuits you need in a single setup. Add blocks for grounding wire as needed. The blocks clip side by side onto DIN rail in control panels, creating tidy rows of circuits that you can identify and access on the spot.
