Connect wires to your circuit board with these Molex KK push-in connectors. A good choice for prototyping, they require less force to disassemble than Amphenol PV connectors. However, this means that they are less secure in more demanding applications.

For a complete connection, choose a plug and housing with the number of poles that matches the number of wires you need to connect. You’ll also need one sleeve for each wire.

Crimpers (sold separately) are required to install wires.

Assemble DB and HD connectors to replace worn out connectors.

Shielded connectors prevent electromagnetic interference.

Connectors with a terminal block wire connection have a contact point inside each hole to create a connection without the need for solder or crimping tools.

90° elbow connectors sit flush against equipment to fit in tight spaces.

Crimpers (sold separately) are required for wire installation for crimp-on connectors. They ratchet to ensure the correct pressure is applied to every crimp.

Use extraction tools (sold separately) to remove the pins after crimping.

Often used to prototype or replace damaged connections, these connectors allow you to access and connect to individual USB pins. They are shielded, so they reduce electrical interference from nearby equipment and devices.

Connectors with screw terminals can be quickly wired onto cable leads and do not require tools such as soldering irons or crimpers to attach.

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).
