Wire Terminals and Terminal Blocks

Quick and Secure Modular
DIN-Rail Mount Terminal Blocks

The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. Push wire into the spring clamp for a secure connection that withstands vibration.

Modular DIN-Rail Mount Terminal Blocks

Use with DIN 3 and DIN 1 rail. Add as many circuits as you need with these terminal blocks and accessories.

Modular Mini DIN-Rail Mount Terminal Blocks

Use with DIN 2 rail. Add as many circuits as you need with these terminal blocks and accessories.

Touch-Safe DIN-Rail Mount Terminal Blocks

Recessed terminals prevent accidental contact with a live circuit.

Terminal Blocks

Mount blocks to a panel or the surface of a machine. Also known as barrier terminal strips.

Space-Saver Terminal Blocks

A single row of terminals fits in narrow spaces.

Quick and Secure Connect Terminal Blocks

The spring-clamp terminals on these blocks make wire installation faster than with other types of terminals. Push wire into the spring clamp for a secure connection that withstands vibration.

High-Current Terminal Blocks

These blocks handle at least twice as much current as standard terminal blocks.

High-Temperature Terminal Blocks

Blocks are made of ceramic to withstand elevated temperatures.

Touch-Safe Terminal Blocks

Pluggable Touch-Safe Terminal Blocks

Combine a plug and a socket to form a terminal block—the two-piece design allows quick disconnection for equipment repairs.

High-Temperature Touch-Safe Terminal Blocks

Blocks are made of ceramic to withstand elevated temperatures.

Enclosure-Mounted Terminal Blocks

Save time when wiring connections in a junction box; these blocks come already installed in an enclosure.

Enclosure-Mounted Terminal
Blocks with See-Through Cover

Inspect the terminal block and wiring without opening the cover.

Through-Panel Terminal Blocks

Blocks mount in a cutout and have terminals on both sides.

Circuit-Board-Mount Terminal Blocks

Solder the pins on these blocks directly to your circuit board.

Distribution Blocks

With the help of distribution blocks, you can take a high-current wire from your power source and connect it to one or more electrical devices.

Harsh Environment High-Current Distribution Bars

Protect connections against corrosion.These bars are tin-plated copper and have stainless steel terminals.

Modular Distribution Bars

Build your own distribution system by adding terminal blocks to these bars.

Push-On Wire Splicing Connectors

Push stripped wires into connectors for a reliable connection that's faster to install than twisting or crimping.

Clamp-On Wire Splicing Connectors

Press down on the clamp to connect wires and pull it up to disconnect.

Cords

Temporary Power Distribution Boxes

Plug these portable distribution boxes into a power source, such as a generator, to power equipment when electricity is not available. They're also known as spider boxes.

Distribution Blocks for Nano M8 and Micro M12 Cords

Connect multiple M8 and M12 cords to create a network between equipment. These blocks are often used to send signal and power to proximity switches and sensors.

Pipe, Tubing, Hose, and Fittings

Right-Angle Flow Rectangular Manifolds

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Straight-Flow Rectangular Manifolds

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Round Manifolds for Hose Lines

Mount these manifolds on the end of a hose line to distribute air, water, or hydraulic fluid to three locations from a single supply source.

Miniature Hex Manifolds

A great solution when space is at a premium, these manifolds are less than an inch in height, yet allow you to supply up to 12 lines from one distribution point.

High-Pressure Brass Threaded Pipe Fittings

These brass fittings have the strength to handle high-pressure applications.

High-Pressure Brass Threaded
Pipe Fittings with Sealant

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

High-Pressure Brass Threaded
Pipe Fittings for Drinking Water

Use these heavy-duty brass fittings for high-pressure drinking water applications.

High-Pressure Plated Brass Threaded Pipe Fittings

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Miniature High-Pressure Brass Threaded Pipe Fittings

When space in your pipe line is limited, choose these miniature fittings that are one inch or less in length.

Miniature Low-Pressure Brass Threaded Pipe Fittings

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

Low-Pressure Brass and Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Straight-Flow Junction Blocks

Use these junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air or fluid to flow straight through the block.

Moisture-Resistant Push-to-Connect
Tube Fittings for Air and Water

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Push-to-Connect Tube Fittings for Air

Brass Push-to-Connect Tube Fittings for Air

Made of brass, these fittings have good corrosion resistance.

Stops and Spacers for DIN Rails

Position terminal blocks, relays, and other components mounted to DIN rails with these stops and spacers.

T-Slotted Framing Manifolds

Distribute compressed air, hydraulic fluid, or water from a single supply to multiple locations.

Fuse Blocks for UL Class Fuses

Temperature and Humidity Monitoring

Terminal Blocks for Thermocouple Wire

Connect thermocouples to extension wire or instrumentation.

Terminal Blocks for RTD Wire

Connect RTD wire leads to conduit or instrumentation.
