Sta-Kon RA147PT INS NYL PIN TERM 12-10 AWG RED

It carries UL file E9809 and is rated 300 V. That 300 V rating covers the usual control and signal wiring in panels, motor control circuits, and appliance wiring. For 600 V class power distribution terminations, specify a terminal rated to 600 V instead.

A pin terminal like the Sta-Kon RA147PT puts a solid round pin on the end of a stranded wire so it can be clamped into a screw-type terminal block, a set-screw connector, or a pressure plate without the strands splaying or backing out under the screw. Use a ring terminal where the connection is a stud with a nut and vibration is a concern, and a fork (spade) terminal where you need to slide the wire out from under a loosened screw without removing it entirely. The pin is the right pick for terminal strips, control panels, and contactor terminals that accept a bare conductor.

The crimp barrel is copper, so it is intended for copper conductors. Terminating aluminum wire calls for a connector specifically listed AL/CU; a copper-only barrel on aluminum invites galvanic corrosion and a high-resistance joint. The insulation sleeve over the barrel is nylon, which holds up better to crimp-tool pressure and to flexing at the wire entry than vinyl does.

Use a ratcheting insulated-terminal crimper with the nest sized to the terminal's color code. The nylon sleeve on the RA147PT is meant to be compressed along with the copper barrel in a single full-cycle crimp; pliers or a general-purpose cutter crimp deform the sleeve, leave the barrel under-compressed, and give you a joint that pulls out or heats up. After crimping, tug-test the wire and confirm no strands escaped the barrel before landing the pin in the terminal block.

Red is the color of this terminal's nylon sleeve, and on insulated crimp terminals the sleeve color is the gauge code rather than a circuit marking. Match the color to the barrel color stamped on your crimp tool nest so the die closes to the correct depth. Do not read the red as a circuit or polarity identifier on a panel.

Order it as Sta-Kon RA147PT, which is both the model and the manufacturer part number. Country of origin is the United States. There is a single configuration, so no finish, length, or packaging suffix needs to be specified on the purchase order.
