Panduit PIN Term Vinyl Insulated 12 1PK50

Panduit PV10-P55-LYY Pan-Term Vinyl-Insulated Pin Terminal

Overview

The Panduit PV10-P55-LYY is a Pan-Term® vinyl-insulated pin terminal designed for 10–12 AWG conductors where a reliable, mechanically secure wire-to-board or wire-to-connector interface is required. With a 14 mm pin length and a tinned (verzinkt) copper finish, this terminal is a workhorse for control panel wiring, security system backplanes, and structured wiring enclosures where vibration, repeated connection cycles, and inspection demands are facts of life. Sold in a 50-piece package (500 per carton), the PV10-P55-LYY fits procurement workflows ranging from a single-panel build to a high-volume rack integration project.

The yellow vinyl insulation is the industry color code for 10–12 AWG, so technicians pulling from a mixed-gauge bin can confirm the correct terminal at a glance — reducing wiring errors in the field without adding a separate QC step.

Key Features

• Rigid Steel Pin, Tinned Finish: The solid pin resists deformation under torque — critical when a technician over-drives a terminal block screw. The tin plating provides corrosion resistance in environments where condensation or marginal humidity control is a reality, such as outdoor-rated enclosures with controlled breathing or basement IDF closets.
• Insulation Support Collar: The collar grips the conductor jacket just behind the crimp zone, preventing the wire from flexing at the crimp interface. In high-vibration installations — access control door frames, elevator shafts, HVAC-adjacent panels — flex fatigue at the crimp point is a leading cause of intermittent faults. This geometry eliminates that failure mode.
• Internal Sleeve Serrations: The serrated inner bore bites into the conductor strands during crimping, maximizing mechanical pull-out strength and ensuring gas-tight electrical contact. This is the difference between a terminal that meets spec on day one and one that still reads zero millivolt drop after years of thermal cycling.
• 10–12 AWG Conductor Range: Covers the wire gauges most common in 120V control circuits, security panel power runs, and low-voltage distribution — the range where panel builders spend the most time. No need to stock a separate SKU for 10 AWG and another for 12 AWG.
• 14 mm Pin Length: Long enough to seat fully in DIN-rail terminal blocks and standard feed-through connectors without requiring a second pass or a longer-pin adapter. The 1.1-inch overall terminal length keeps it compact inside crowded enclosures.
• Yellow Vinyl Color Coding: Yellow = 10–12 AWG by IEC and industry convention. In a panel with multiple wire gauges, color coding eliminates the need to measure or check print labels during assembly — the color IS the spec check.
• 50-Piece Pack, 500-Piece Carton: The 50-pack is sized for a single-panel job; the 500-piece carton suits integrators running multiple concurrent installations or maintaining a van stock. Both quantities ship as discrete SKUs, so you order what you need without surplus.

Integration & Compatibility

The PV10-P55-LYY is engineered for use with specific Panduit crimp tools to achieve the manufacturer's specified pull-out force and contact resistance. Compatible crimp tools include the CT-100, CT-1550, CT-1551, CT-2300 (with CD-550 die), CT-2500 / CT-2550CH, and the UP14ZLW (with CD-550 die). Using an incompatible or non-calibrated tool with this terminal will not produce a gas-tight crimp and may result in elevated contact resistance or premature pull-out failure — a common field problem when technicians substitute a generic ratchet crimper.

For projects involving wire termination components across multiple gauge ranges, the Pan-Term® line covers AWG 22 through 2/0, allowing a single-source procurement approach. Pair these terminals with Panduit wiring infrastructure products — duct, ties, and markers — for a fully coordinated installation.

If you are sourcing terminals for a structured security or access control panel build, review our cable management and power distribution categories for complementary components that integrate directly with the same DIN-rail and enclosure form factors.

Frequently Asked Questions

Q: What wire gauge does the PV10-P55-LYY accept?

A: The PV10-P55-LYY is rated for 10–12 AWG conductors. Yellow vinyl insulation confirms the gauge range by color per industry convention.

Q: Which crimp tools are compatible with the PV10-P55-LYY?

A: Panduit specifies the CT-100, CT-1550, CT-1551, CT-2300 (with CD-550 die), CT-2500/CT-2550CH, and UP14ZLW (with CD-550 die). Using an uncalibrated or non-specified tool risks an incomplete crimp and elevated contact resistance.

Q: How many terminals are included per package and per carton?

A: Each package contains 50 terminals. The full carton quantity is 500 pieces.

Q: What is the pin length and overall terminal length of the PV10-P55-LYY?

A: The pin length is 14 mm. Overall terminal length is 1.1 inches.

Q: Is the PV10-P55-LYY (often searched as PV10 P55 LYY) suitable for outdoor or humid environments?

A: The tin-plated (verzinkt) pin finish provides corrosion resistance suitable for environments with incidental moisture exposure, such as vented outdoor enclosures or conditioned mechanical rooms. It is not rated for direct submersion or caustic chemical exposure.

Q: Does this terminal require a specific insulation strip length?

A: Panduit does not publish a specific strip length in the available product data, but standard practice for a 14 mm pin terminal is an 8–10 mm strip. Follow the crimp tool manufacturer's die guide for the CT-series tools specified for this terminal.

Karl Wilson

When I spec pin terminals for a security panel build, the first question is always pull-out integrity under thermal cycling — and that is exactly where the PV10-P55-LYY earns its place. The internal sleeve serrations are not a marketing feature; they are the mechanism that maintains gas-tight contact after dozens of heat cycles in a warm equipment room. I have seen generic pin terminals with smooth bores read 50–100 milliohm contact resistance after six months in a panel that runs hot. The PV10-P55-LYY's serrated crimp geometry prevents that.

Technical Highlights:

• 10–12 AWG Dual-Gauge Coverage: A single SKU handles both 10 and 12 AWG, which covers most 120V control circuits and 12V security panel power runs — reduces your terminal inventory to one line item for the majority of panel wiring.
• 14 mm Pin Length: Seats fully in standard DIN-rail feed-through and terminal block connectors without a secondary adapter. At 1.1 inches overall, it stays compact enough for high-density wiring troughs.
• Tinned Copper Finish: Tin plating resists oxidation in environments below 100% RH, including vented outdoor enclosures and mechanical rooms — extends service life without requiring periodic re-termination.

Deployment Considerations:

• Tool compatibility is non-negotiable: the PV10-P55-LYY is specified for CT-100, CT-1550, CT-1551, CT-2300 (CD-550 die), CT-2500/CT-2550CH, and UP14ZLW (CD-550 die). Substituting a generic ratchet crimper will not produce the correct die geometry for this terminal barrel and will undermine pull-out strength — expect field callbacks.
• The 50-piece pack is the right unit for a single panel; if you are stocking a service vehicle or running a multi-site project, the 500-piece carton (UPC 61305675791) is the better procurement unit — do not mix pack quantities in a single job BOM without confirming the per-unit price holds.

For access control and security panel integrators building high-density wiring enclosures — where vibration from HVAC, door hardware, or elevator proximity is a factor — the PV10-P55-LYY's combination of insulation support collar and serrated sleeve makes it the right call over a bare or smooth-bore alternative. Specify it alongside the correct Panduit CT-series tool and it will not be the source of your next field callback.
