Panduit EV10-P55-QYY StrongHold Vinyl-Insulated Pin Terminal

Overview

The Panduit EV10-P55-QYY is a StrongHold™ vinyl-insulated pin terminal (pin ferrule) designed for reliable wire termination on 12–10 AWG conductors. With a 0.55-inch pin length and a tin-plated barrel, it's built for panel wiring, DIN-rail terminal blocks, and control-cabinet connections where a solid cylindrical contact interface is required — not a fork or ring lug. If you're wiring into Phoenix Contact-style or similar screw-cage terminal blocks, this form factor is what those connectors are engineered to accept. At 1.1 inches overall length, the EV10-P55-QYY stays compact enough to maintain clean wire management in tight control enclosures without the pin protruding past the terminal block face.

Key Features

• 12–10 AWG Conductor Range: Accommodates the heavier end of the control-wiring spectrum. 12 AWG is common for 20A branch circuits in panel builds; 10 AWG appears on higher-current sensor or relay feeds. One terminal covers both gauges — fewer SKUs to stock on a panel-build job.
• 0.55-Inch Pin Length: The pin depth determines how far the terminal seats into a screw-cage or push-in block. At 0.55 inches, this matches the insertion depth on CT-series Panduit tools and the terminal blocks they're designed for — use a different pin length and you risk a shallow seat, higher contact resistance, or block damage.
• Vinyl Insulation: The vinyl sleeve provides electrical isolation right up to the barrel entry, which matters when terminals are densely packed in a row. It also gives a color-coding surface — standard practice in European-style panel wiring where wire gauge is coded by ferrule color.
• Tin-Plated (Verzinkt) Barrel: Tin plating resists oxidation at the crimp interface, which is the failure point on bare-copper ferrules in humid or mildly corrosive environments. For control panels in warehouses, mechanical rooms, or light industrial settings, this adds longevity without requiring a silver or gold contact.
• 1.1-Inch Overall Length: A compact footprint that keeps wire stubs short and reduces the risk of wire stress at the insulation transition — a common cause of intermittent faults in vibrating or frequently-serviced enclosures.
• Panduit StrongHold™ Series: Part of Panduit's professional wire termination line, these terminals are sized and dimensioned for use with Panduit's CT-series crimping tools, ensuring consistent crimp geometry and pull-force performance across the installation.

Integration & Compatibility

The EV10-P55-QYY is designed for use with the following Panduit crimping tools: CT-100A, CT-260, CT-1550, CT-1551, CT-2300/ST with CD-550 die, and CT-2500/L with CT-2550CH die. Tool-terminal pairing is not optional — using an off-brand or mis-sized crimper on a pin ferrule produces inconsistent barrel deformation, which can fail pull testing or cause intermittent contact inside the terminal block. If you're already running any of the listed CT-series tools on a job, this terminal drops straight into your existing workflow. If you're sourcing tools separately, confirm die compatibility before ordering in volume. These pin terminals are compatible with standard IEC-style screw-cage and spring-cage terminal blocks that accept 0.55-inch pin inserts — verify your terminal block manufacturer's specified pin length before committing to this SKU vs. a longer or shorter variant.

Frequently Asked Questions

Q: What wire gauge does the EV10-P55-QYY accept?

A: The EV10-P55-QYY is rated for 12–10 AWG conductors. It will not properly crimp onto finer gauges (14 AWG and smaller) — use a terminal in the correct AWG range for those conductors.

Q: Which crimping tools are compatible with the EV10-P55-QYY?

A: Panduit specifies the CT-100A, CT-260, CT-1550, CT-1551, CT-2300/ST with CD-550 die, and CT-2500/L with CT-2550CH die. Always match the terminal to a listed tool to ensure correct crimp geometry.

Q: How many terminals come in a package?

A: Each package contains 25 terminals. The standard carton quantity is 250 (10 packages per carton).

Q: What is the pin length on the EV10-P55-QYY?

A: The pin length is 0.55 inches. Verify that your terminal block accepts this insertion depth before ordering — mismatched pin lengths can result in shallow seating and elevated contact resistance.

Q: What type of insulation does the EV10-P55-QYY use?

A: Vinyl insulation. The sleeve provides electrical isolation at the barrel entry and a surface for color coding, which is standard practice in IEC-style control panel wiring.

James Everett

The EV10-P55-QYY is a straightforward ferrule for 12–10 AWG work, but the 0.55-inch pin dimension is the spec that determines whether this part belongs on your job or not. I've seen panel builds where the wrong pin length was ordered in volume — too short and the terminal floats in the block, too long and you can't close the clamp or you crack the housing. Confirm your terminal block's specified insertion depth against that 0.55-inch figure before you commit to a carton of 250.

Technical Highlights:

• 12–10 AWG Range: Covers the heavier control-wiring gauges in a single SKU — useful when a panel design mixes 12 AWG branch wiring with 10 AWG higher-current feeds on the same terminal strip.
• Tin-Plated Barrel: Oxidation resistance at the crimp joint matters in enclosures that see humidity cycling. Tin plating on the EV10-P55-QYY barrel extends contact reliability compared to bare copper in those environments.
• Tool-Specific Crimp Geometry: Designed for CT-1550, CT-2300/ST, and CT-2500/L among others — the barrel wall thickness and die profile are matched to produce a consistent, pull-tested crimp. Off-tool crimps void that consistency.

Deployment Considerations:

• Die selection matters: the CT-2300/ST requires the CD-550 die and the CT-2500/L requires the CT-2550CH die — confirm die availability before purchasing the terminal separately from your tool kit.
• Vinyl insulation is not rated for high-temperature environments; if your enclosure runs hot (motor drive cabinets, for example), verify the insulation temperature rating against your application before specifying.

This terminal is the right choice for integrators building IEC-style control panels — access control head-end enclosures, intercom power distributions, or industrial automation cabinets — where pin ferrules are the standard interface for screw-cage or spring-cage terminal blocks and wire pull-out force needs to meet a repeatable spec.
