Product Overview
The Cal Test Electronics CT2989-2 is a modular, fixed-sheathed 4mm banana plug built for field-assembly test leads and custom lab cabling. Solderless wire termination relies on dual 1.5mm hex set screws to clamp both conductor and insulation firmly in place, bypassing the need for a soldering station. Rated for 1000V CAT III and 600V CAT IV applications at up to 36A continuous current, the connector features a nickel-plated lantern spring contact with an insulated non-conductive tip for safety in electrical measurement environments.

Frequently Asked Questions
What wire size does this connector accept?
The connector accepts stranded wire up to 12 AWG, with an outer jacket diameter up to 4.0mm.
What tools are required to assemble this plug?
Assembly requires a 1.5mm hex wrench to secure the two internal set screws. No soldering equipment is needed.
Will this plug mate with standard recessed multimeter jacks?
Yes. The fixed shroud is dimensioned to mate with standard 4mm sheathed safety jacks on digital multimeters and test equipment.
Why buy individual CT2989-2 plugs from PartsMine rather than a pre-packaged multipack?
Ordering from PartsMine lets you purchase the exact count of connectors your build requires without getting stuck with excess parts or unused colors. Each connector ships as a complete, inspected three-piece assembly ready for assembly. If your bench needs multiple units, more pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, qualify for free shipping on orders over $28, and ship same or next business day from our Idaho warehouse.
Nothing beats the satisfaction of building a test lead to the exact length your bench actually needs. Tighten the two set screws, snap the boot home, and put your meter back to work.
