Panduit EDV18-250P-LYY StrongHold Vinyl-Insulated Piggyback Disconnect Terminal
Overview
The Panduit EDV18-250P-LYY is a tinned, vinyl-insulated piggyback disconnect terminal from the StrongHold™ line, designed for 22–18 AWG wire and a 0.250" × 0.032" tab. The piggyback configuration allows two conductors to share a single spade connection point without requiring additional terminal blocks or splicing — a time-saver when branching a signal or power circuit at an existing termination. Available in packages of 50 (carton of 500), the EDV18-250P-LYY fits controlled-quantity procurement for panel wiring, machine builds, and field service kits.
Key Features
- 22–18 AWG Wire Range: Covers the most common control-wiring gauges in security panels, intercom systems, and low-voltage distribution — one SKU handles the bulk of your termination needs without stocking multiple sizes.
- 0.250" × 0.032" Tab Size: Matches the industry-standard quarter-inch spade tab found on relays, terminal strips, and push-on connectors; no adapter or modification required when mating with standard receptacle housings.
- Piggyback Design: The stacked-tab geometry lets a second conductor share the same connection point. In access control or intercom wiring where a trigger signal branches to two devices, this eliminates a splice or junction block and keeps the termination compact inside the enclosure.
- Tinned Barrel Finish: The electro-tinned copper barrel resists corrosion at the wire-to-terminal interface, maintaining low contact resistance over time in environments where humidity or mild condensation is possible — relevant inside outdoor-rated enclosures and basement panel rooms.
- Vinyl Insulation Sleeve: The vinyl sleeve provides mechanical protection against shorts to adjacent terminals and chassis ground, critical in densely wired panels where bare conductors in close proximity are a fault risk.
- StrongHold™ Sub-Brand: Panduit's StrongHold line is engineered for consistent crimp geometry and barrel integrity under the tooling forces of compatible crimpers, reducing the risk of cold or flared crimps that increase resistance and fail pull-out tests.
- Compatible Crimping Tools (CT-100A, CT-260, CT-1550, CT-1551, CT-2300/ST, CT-2500/L): Panduit specifies six tools for this terminal — use only these. Mismatched tooling deforms the barrel, compromises the gas-tight crimp, and voids dimensional compliance. The CT-1550 and CT-2500/L cover the full 22–18 AWG range with die indexing.
- Package Quantity of 50, Carton of 500: The 50-piece pack suits field service kits and small panel jobs without over-ordering. The 500-piece carton (EDV18-250P-LYY, often searched as EDV18 250P LYY) supports production wiring runs or stocking rooms where this gauge-tab combination is a repeated build item.
- 0.88" Overall Length, 0.29" Overall Width: Compact footprint allows termination in tight enclosure sections, including 4" deep distribution panels and narrow DIN rail zones where larger terminals create routing conflicts.
Integration & Compatibility
The EDV18-250P-LYY is intended for use with Panduit crimping tools CT-100A, CT-260, CT-1550, CT-1551, CT-2300/ST, and CT-2500/L. The 0.250" tab size mates with standard quarter-inch push-on receptacles found on relays, solenoids, terminal blocks, and connector housings across security, building automation, and light industrial control applications. Wire range 22–18 AWG covers stranded and solid conductors typical in low-voltage security and access control wiring. Confirm your wire gauge and tab receptacle dimension before ordering — the EDV18-250P-LYY does not fit 0.187" or 0.110" tab receptacles, and it is not rated for 16 AWG or heavier conductors.

Frequently Asked Questions
Q: What wire gauge range does the EDV18-250P-LYY accept?
A: The EDV18-250P-LYY is rated for 22–18 AWG wire. It is not designed for 16 AWG or heavier conductors — using out-of-range wire will compromise the crimp and may not pass pull-out testing.
Q: What tab size does the EDV18-250P-LYY use, and will it fit standard push-on receptacles?
A: The tab is 0.250" × 0.032", which is the standard quarter-inch spade tab. It mates with 0.250" push-on receptacles but will not fit 0.187" or 0.110" tab housings.
Q: Which Panduit crimping tools are compatible with the EDV18-250P-LYY?
A: Panduit specifies the CT-100A, CT-260, CT-1550, CT-1551, CT-2300/ST, and CT-2500/L for this terminal. Use only listed tools — mismatched tooling will deform the barrel and compromise the crimp.
Q: How many terminals come in a package, and is a larger carton available?
A: Each package contains 50 terminals. The full carton quantity is 500 pieces, suitable for production wiring or high-volume stocking.
Q: What is the piggyback design useful for in panel wiring?
A: The piggyback tab allows a second conductor to share the same spade connection without adding a splice or junction block. This is practical when branching a trigger or power signal to two devices at the same termination point inside a panel enclosure.
The EDV18-250P-LYY is a detail-level component, but it's the kind of part that causes callbacks when it's wrong. The piggyback geometry on this StrongHold terminal is useful specifically because the 0.250" tab stacks — so when you're wiring a door strike that also needs to report status back to an access controller, you get both conductors on one spade without adding a terminal block row or an in-line splice that could work loose over time.
Technical Highlights:
- Tinned Barrel: The electro-tinned finish maintains low contact resistance at the wire-barrel interface — particularly relevant in enclosures subject to humidity cycling where bare copper would oxidize and increase resistance over time.
- 22–18 AWG Range: Covers the control-wiring sweet spot for access control, intercom, and relay circuits; a single SKU handles the gauge variation you'll encounter across most low-voltage panel builds without stocking a second size.
- Tool Compatibility (CT-1550, CT-2500/L and four others): Panduit's six-tool spec list is not arbitrary — the die geometry indexes to the barrel dimensions of the EDV18-250P-LYY. A generic crimper at the same AWG setting will produce an inconsistent barrel compression that looks fine visually but fails pull-out force spec.
Deployment Considerations:
- Verify your receptacle tab size before ordering — the 0.250" tab will not insert into 0.187" receptacles commonly found on older relay bases and some European DIN-rail terminal housings. Measure, don't assume.
- The 50-piece pack (MOQ 10 packs per the product designation) is sized for field kits and small panel jobs; if you're wiring a multi-door access system with frequent signal branching, order the 500-piece carton quantity to avoid mid-job stock-outs.
This terminal is the right call for access control and intercom panel wiring in commercial installations where the piggyback branch point eliminates a junction block and keeps the enclosure interior clean — particularly in retrofit projects where panel space is already constrained.
