Quickly troubleshoot or change wiring without any tools. These terminal blocks have a lever clamp that you flip up to insert wiring and flip down to lock it in place. For more permanent connections, they also have one or two spring-clamp terminals. You’ll need a slotted screwdriver to release the spring clamp that holds the wire in place. All wire connections stand up to vibration and temperature changes. Add as many circuits as you need with these blocks and accessories. The blocks mount side-by-side on DIN 3 rail.

Rated UL 94 V-0, all meet flammability standards.

Grounding terminal blocks facilitate grounding circuits by electrically connecting wires to DIN rail. They shouldn’t be used for applications other than grounding.

End covers fit on the open side of a block to prevent accidental contact with a live circuit.

End stops mount at the end of a group of blocks to keep them in place.

Jumpers connect circuits between blocks to simplify wiring and leave terminals available to connect equipment. These jumpers are lateral jumpers, so they connect to blocks in place of wire or in addition to a wire at the terminal connection points.

Marker cards fit into built-in label holders on the blocks.

Visually confirm your circuits are working as expected. These terminal blocks have integrated LEDs that indicate if your circuits are powered or not, helping you troubleshoot issues. They're commonly used with sensors and actuators to communicate their status. You can add as many circuits as you need with these terminal blocks and accessories; they mount side-by-side on DIN 3 rail. They’re ideal for processing plants and on conveyor lines because they make it easy to organize multiple sensors and actuators. Once you’ve wired the first block in the series to a power supply, jumpers (sold separately) power each connected block. The other terminals on each block connect your PLC or data logger to the signal wire of your sensor or actuator.

When wiring these blocks, there’s no need to tighten or loosen any screws thanks to their spring-clamp terminals. Insert a slotted screwdriver to release the spring clamp and then push your wire in to lock it into place.

Rated UL 94 V-0, all meet flammability standards.

Blocks for PNP signal output illuminate when sensors are sending a high signal.

Blocks for NPN signal output illuminate when sensors are sending a low signal.

End covers fit on the open side of a block to prevent accidental contact with a live circuit.

End stops mount at the end of a group of blocks to keep them in place.

Jumpers connect circuits between blocks to simplify wiring and leave terminals available to connect equipment. These jumpers are lateral jumpers, so they connect to blocks in place of wire or in addition to a wire at the terminal connection points.

One of the connections on these terminal blocks is a socket instead of a traditional terminal, making it easy to swap out equipment or change your wiring even in small enclosures. Instead of having to attach wire inside the tight space of your enclosure, you can wire a connector (sold separately) wherever it’s easiest and then plug it into the socket. For more permanent connections, these blocks also have spring-clamp terminals. You’ll need a slotted screwdriver to release the spring clamp that holds the wire in place. Add as many circuits as you need with these blocks and accessories. They mount side-by-side on DIN 3 rail.

Add as many circuits as you need with these terminal blocks and accessories. The terminal blocks clip onto DIN 2 rail. All blocks are rated UL 94 V-0, so they meet flammability standards. They’re IP20 rated to protect connections from objects larger than 12.5 mm, such as fingers.

Spring-clamp terminals make wire installation faster than screw-clamp terminals. These wire connections also stand up to vibration and temperature changes. Insert a slotted screwdriver to release the spring clamp and then push your wire into place.

Jumpers connect circuits between blocks to simplify wiring and leave terminals available to connect equipment. They’re adjacent jumpers, so they connect terminals on adjacent blocks of the same width. Marker cards fit into built-in label holders on the blocks.

The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. These wire connections also stand up to vibration and temperature changes. Use your finger to release the spring clamp and then push your wire into place. All blocks are rated UL 94 V-0, so they meet flammability standards.

Use DIN rail adapters to mount blocks to DIN 3 rail. Two adapters per block are required, except the two-circuit blocks need only one adapter.

Save time when wiring connections in a junction box. These blocks come already installed in an enclosure. All enclosures are IP and NEMA rated to seal out dust and protect against corrosion. They meet UL 94 flammability standards.

Spring-clamp terminals make wire installation faster than screw terminals. Push the wire into the spring clamp for a secure connection that withstands vibration.

ABS plastic and polycarbonate enclosures are lightweight and resist denting, chipping, and cracking. The polycarbonate enclosures also come with cord grips that are watertight. IP65 rated enclosures can be rinsed off. NEMA 4X and NEMA 6 rated enclosures protect against washdowns and weather conditions such as rain, snow and sleet. NEMA 4X enclosures also have increased protection against corrosion, similar to stainless steel.

Push stripped wires into connectors for a reliable connection that's faster to install than twisting or crimping. All have individual ports for each wire.

Connectors with a 150V AC maximum voltage have connecting flanges that are useful if you're attaching multiple connectors together. Slide the flanged side of one connector into the grooved side of another.

Connectors with a 600V AC/DC maximum voltage have a clear housing, so you can visually confirm your connection.

DIN rail adapters (sold separately) allow you to mount the connector to a 35 mm DIN rail.

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.
