No need to tighten or loosen any screws—these terminals lock your wiring in place with spring clamps. Insert a slotted screwdriver to release the spring clamp and then push your wire into place. Spring-clamp wire connections withstand vibration and temperature changes. You can add as many circuits as needed with these terminal blocks and accessories; 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.

Blocks with a fuse holder protect components and wire from short-circuit damage by enclosing the fuse.

Blocks with a blown fuse indicator light up so you’ll know if your fuse is blown without having to touch equipment or disconnect power.

Use blocks with a disconnect tab to toggle your circuit open and closed for testing.

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. Adjacent jumpers connect terminals on adjacent blocks of the same width. Alternate jumpers connect terminals on two blocks of the same width, skipping a block in between.

Marker cards fit into built-in label holders on the blocks. Numbered marker cards include two of each number (1-50).

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.

All blocks are rated UL 94 V-0, so they meet flammability standards.

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. Noninsulated jumpers can be cut to size.
