SquarePlug SPS4BK Compact Short Straight 1/4" TS Mono Cable Plug (Black)

Black SquarePlug SPS4BK short straight 1/4-inch TS cable plug

This Black SquarePlug SPS4BK is a compact, straight 1/4-inch TS mono cable-end plug for cables with a 4.0–4.6 mm outside diameter. It uses two tip-and-sleeve solder tabs and a two-screw cable clamp for strain relief. This listing is for one connector, not a finished cable or a multipack.

Cable compatibility and connection type

Fits 4.0–4.6 mm outside-diameter cable. The listed compatible cable options include Mogami W2314, Canare GS-4, Belden 1865A, and Belden 8218. Check your cable's actual jacket diameter and termination requirements before ordering.

This is a two-contact TS connector for unbalanced mono cable builds, not a three-contact TRS plug for balanced mono or stereo wiring. Match the cable and tip/sleeve wiring to your equipment's requirements.

Check clearance before building

The shell is listed as 13 mm in diameter and 20 mm long. The existing product dimensions also list approximately 21 mm projection when plugged in and just under 14 mm across the screw-head area. Check jack spacing, recessed sockets, adjacent connectors, and room for the cable exit rather than assuming a universal fit.

For a matching right-angle option, the SPS4BK listing identifies SquarePlug SP400BK.

Assembly and identification

Soldering and cable assembly are required. Follow the connector manufacturer's preparation instructions, use the insulation tube, secure the jacket with the two-screw clamp, and check continuity and shorts before use. The cable clamp helps keep movement away from the solder joints.

Optional colored screws provide cable identification using two screws per connector. The listed system offers ten colors and 55 combinations; color-coding screws are optional, not included as a full set with this connector.
