    Plastic Press-Fit Low-Profile Binding Barrels and Caps

    Plastic binding barrels are chemical resistant, nonconductive, and lightweight. The barrel is unthreaded for quick assembly with a press or a hammer. The barrel and cap have a low-profile for a nearly flush finish with the material surface. Barrel length is measured from under the head. Barrels and caps are sold separately.

    Install and service setups for two, three, and five wires, then reuse these connectors later. They pop on and off wire with the flip of a clamp to save time over crimping. Choose them for setups that change often, such as prototypes and testing. They even have test sockets to safely test voltage after installation. The assortments include DIN-rail adapters so you can snap connectors into a control panel.

    Watertight Insulation-Piercing Butt Splices

    Image of Product. Front orientation. Wire Splices, Connectors, and Taps. Watertight Insulation-Piercing Butt Splices.
    A gel filler seals out water to keep your wires completely dry and conductive. No need to strip your wire—insert insulated wires into the splice, then squeeze the button with a crimper or pliers until it clicks. The splice bites through the insulation, so you don't take extra time or risk nicks and cuts from a wire stripper. Snap splices together to create the exact setup you need.

    Covers

    Flip a clamp onto your wire instead of crimping to speed up installations, then reuse these connectors later. The clamp secures and disconnects wires without damaging them. Choose these connectors for setups that change often, such as prototypes and testing. They even have test sockets to safely test voltage after installation.
    DIN Rail Mounting Adapters—Clip connectors onto DIN 3 rail to keep them organized and easily accessible.
    Covers—Seal out moisture to protect your connection. Covers are lined with a sticky gel, so you don't need to mix or pour a potting compound yourself. They’re rated IP08 to withstand splashes, rain, and humidity. To repair or expand your circuit, open the cover and remove the wires so you can reuse them. However, you'll need to replace the splice and cover after you open the cover and remove the gel.

    Watertight Reducing Insulation-Piercing Butt Splices

    Image of Product. Front orientation. Wire Splices, Connectors, and Taps. Watertight Reducing Insulation-Piercing Butt Splices.
    Connect two components with different wire sizes, such as an air compressor and its control panel. Also known as step-down splices, these splices join a larger wire and a smaller wire end to end. The larger and smaller openings are color coded so you don't have to measure and mark them yourself. You can snap splices together to create the exact setup you need.
    A gel filler seals out water to keep your wires completely dry and conductive. No need to strip your wire—insert insulated wires into the splice, then squeeze the button with a crimper or pair of pliers until it clicks. The splice bites through the insulation, so you don't take extra time or risk nicks and cuts from a wire stripper.

    DIN Rail Mounting Adapters—Clip connectors onto DIN 3 rail to keep them organized and easily accessible.
    Covers—Seal out moisture to protect your connection. Covers are lined with a sticky gel, so you don't need to mix or pour a potting compound yourself. They’re rated IP08 to withstand splashes, rain, and humidity. To repair or expand your circuit, open the cover and remove the wires so you can reuse them. However, you'll need to replace the splice and cover after you open the cover and remove the gel.
