Panduit PN10-10R-L Nylon Insulated Ring Terminal, 12-10 AWG, #10 Stud, PK50

The Panduit PN10-10R-L is a Pan-Term® nylon insulated ring terminal designed for wire termination in high-vibration environments. Rated for 10-12 AWG conductors and a #10 stud, this terminal combines a metal insulation grip sleeve, internal barrel serrations, and funnel entry to deliver a reliable, strain-relieved crimp joint where connection integrity under mechanical stress is not optional. Sold in packs of 50 (PN10-10R-L, often searched as PN10 10R L), it suits electrical contractors and panel builders who need a standards-verified, field-proven termination in quantity.

Overview

Part of Panduit's Pan-Term® termination line, the PN10-10R-L is built around three structural features that collectively address the failure modes common in vibration-prone installations: the ring tongue locks down to prevent backing off the stud, the metal grip sleeve transfers mechanical load away from the conductor crimp, and serrated barrel geometry maximizes surface contact to resist pull-out. The yellow color coding identifies the 12-10 AWG range at a glance — a small but meaningful time-saver when sorting a panel's worth of wire termination hardware. Overall dimensions are 1.06 in. length by 0.38 in. (9.7 mm) width.

Key Features

• Ring Tongue Design: The closed-ring geometry keeps the terminal captive on the stud even when the nut is only partially torqued — critical in vibrating machinery or vehicle enclosures where a spade terminal would walk off. If a lost connection in the field means a service call, the ring tongue is the right choice.
• Metal Insulation Grip Sleeve: The sleeve crimps onto the wire insulation, not just the conductor, distributing mechanical stress across a longer section of the wire bundle. In high-vibration environments this prevents the fatigue cracking at the crimp barrel entry point that is the primary cause of terminal failures over time.
• Internal Barrel Serrations: Serrations displace wire strands radially during crimping, increasing contact area and mechanical interlock. Panduit specifically calls out maximum tensile strength — relevant when the terminal is used on conductors subject to pull forces in addition to vibration.
• Funnel Entry: The flared barrel mouth guides individual wire strands in during insertion, reducing strand pop-outs that would drop the effective conductor cross-section and raise resistance at the joint. On a busy bench or in a confined panel, funnel entry speeds consistent crimps.
• Tin-Plated Copper Contact: Tin plating resists oxidation at the contact interface, maintaining low-resistance connection over the product's service life without requiring conductive grease or periodic re-torquing in most indoor environments.
• Nylon Insulation, UL 94 HB Rated: UL 94 HB is a horizontal burn classification — the nylon insulation self-extinguishes after the ignition source is removed. This meets the flame-spread requirements for many panel and enclosure applications and is the baseline flammability rating called out in UL and CSA listings for this terminal type.
• Certifications — cULus, CSA, Military QPL: cULus Listing 587H E52164 and CSA Certification LR31212 mean the terminal has been independently tested to North American wiring standards — a requirement on most commercial and industrial jobs. The Military QPL AS7928 (MS25036-112) listing expands acceptable use to defense and aerospace applications where QPL compliance is contractually required.
• Pack of 50, Carton of 500: The PK50 pack quantity suits single-panel or small-batch jobs without over-buying. Cartons of 500 are available for volume pulls, and the consistent pack size simplifies material tracking on cable management and termination projects.

Integration & Compatibility

The PN10-10R-L is compatible with Panduit crimping tools including the CT-100, CT-1550, CT-1551, CT-2300/ST (CD-550), CT-2500/L (CT-2550CH), and UP14ZLW (CD-550). Using the correct Panduit crimp tool ensures the barrel collapses to the engineered geometry — an out-of-spec crimp tool can under- or over-compress the barrel, voiding the tensile strength and UL listing of the connection. The #10 stud size is compatible with standard 10-32 and 10-24 machine screws as well as #10 bolts, covering the majority of terminal block and grounding lug configurations found in North American industrial panels. Wire range of 10-12 AWG covers the conductors most commonly used on 20A and 30A branch circuits in security system power distribution, access control panels, and low-voltage control wiring.

Frequently Asked Questions

Q: What AWG wire range does the PN10-10R-L accept?

A: The PN10-10R-L is rated for 10-12 AWG conductors. The yellow color coding on the nylon insulation sleeve indicates this wire range per standard color-coding conventions.

Q: What stud size does this ring terminal fit?

A: The PN10-10R-L is designed for a #10 stud, compatible with #10-32 and #10-24 machine screws and bolts.

Q: Which Panduit crimp tools are approved for the PN10-10R-L?

A: Panduit specifies the CT-100, CT-1550, CT-1551, CT-2300/ST (with CD-550 die), CT-2500/L (CT-2550CH), and UP14ZLW (with CD-550 die) for this terminal. Using the correct die set is necessary to achieve the listed tensile strength and maintain UL listing.

Q: Is the PN10-10R-L listed to any military or aerospace standards?

A: Yes. In addition to cULus Listing 587H E52164 and CSA Certification LR31212, the PN10-10R-L meets Military QPL AS7928 (MS25036-112), qualifying it for defense and aerospace applications where QPL compliance is contractually specified.

Q: What is the flammability rating of the nylon insulation?

A: The nylon insulation is rated UL 94 HB, meaning it passes the horizontal burn test and self-extinguishes after the ignition source is removed. This meets the flame-spread requirements for most commercial panel and enclosure applications.

Q: How many terminals come per package, and is a larger quantity available?

A: The PN10-10R-L ships in packs of 50. A carton quantity of 500 is available for higher-volume termination work.
