Panduit PV22-8R-MYY Pan-Term® Ring Terminal
The Panduit PV22-8R-MYY is a vinyl-insulated ring tongue terminal engineered for 12-10 AWG wire and #8 stud connections in security, access control, and low-voltage power applications. Part of the Pan-Term® product line, this terminal combines a funnel-entry design for fast wire insertion with internal barrel serrations that grip conductors for pull-out resistance up to UL 486A-486B standards. The closed-barrel crimp construction and tin-plated copper contact deliver reliable current flow in installations where vibration, thermal cycling, or repeated mechanical stress would compromise lesser connectors. Packaged 1,000 pieces per reel, this terminal is specified for battery backup systems, access control panels, fire alarm circuits, and PoE lighting retrofits where Code-compliant terminations and inspector-friendly installations matter.
Key Features
- 12-10 AWG wire range with #8 (0.164") stud hole for UPS, access control, and alarm panel terminations
- Tin-plated copper barrel resists corrosion in plenum spaces, outdoor enclosures, and coastal environments
- Internal barrel serrations bite into stranded conductors for 300+ lbf tensile strength per UL 486A
- Vinyl insulation support prevents wire fatigue at crimp exit point during panel vibration and conduit pulls
- Butted-seam barrel construction eliminates crimp-through failures on automated tooling
- Yellow color-coded sleeve speeds gauge identification during QA inspections and troubleshooting
- Compatible with Panduit CT-series crimp tools and industry-standard ratcheting crimpers
- 1,000-piece bulk reel packaging reduces cost-per-termination on multi-building rollouts
The PV22-8R-MYY addresses a core problem in low-voltage installations: wire terminations that loosen over time. Access control mag locks, alarm panel auxiliary power outputs, and emergency lighting inverters all generate mechanical vibration or thermal expansion that works screw terminals loose. This terminal's ring tongue design keeps the connection captive even when the screw backs out a quarter-turn — the closed loop can't slip off the stud. The vinyl insulation support barrel extends 0.12" past the crimp zone to reinforce the wire jacket exactly where bending stress concentrates during panel dressing. That support prevents the individual strands from work-hardening and fracturing at the crimp mouth, a failure mode that shows up 18–36 months into service when troubleshooting intermittent faults becomes expensive.
Tin plating over copper delivers two installation advantages. First, the tin surface resists oxidation in plenum return-air spaces where humidity condenses on cold mornings — bare copper forms a non-conductive oxide layer that increases contact resistance and generates heat under load. Second, tin-to-brass stud contact (common in terminal blocks and panel lugs) creates a more stable joint than copper-to-brass because the tin layer prevents galvanic corrosion between dissimilar metals. In coastal or industrial environments where airborne contaminants accelerate corrosion, tin-plated terminals extend service life 3–5× over unplated copper. The 0.78" overall length and 0.26" width fit into crowded panel interiors where space between DIN rail and enclosure wall runs tight — you can stack two terminals on adjacent studs with 0.5" center-to-center spacing without insulation contact.
Crimping tooling matters for Code compliance and long-term reliability. This terminal is compatible with Panduit's CT-100 hand tool (ratcheting, one-hand operation), CT-1525 and CT-2300 hydraulic tools for production volumes, and the CT-2500/L battery-powered tool for field work. The specified dies create a crimp that meets UL 486A-486B pull-out and temperature-rise requirements without over-compressing the barrel (which fractures strands and reduces conductivity). For integrators running hundreds of terminations per job, the 1,000-piece reel format and tool compatibility mean you can standardize on one terminal size for door controllers, panel auxiliary power, and PoE injector DC inputs — reducing inventory SKUs and training time for installation crews. This terminal is the spec-grade choice when the job requires inspector-approved terminations, vibration resistance, and a price point that works on competitive-bid projects.
