Panduit EDNF14250FIMB-L StrongHold Insulated Nylon Male Disconnect Terminal
Overview
The Panduit EDNF14250FIMB-L is a fully insulated, nylon male disconnect terminal from the StrongHold™ series — a loose-piece crimp terminal designed for 16–14 AWG wire terminations where reliable mechanical and electrical connections are non-negotiable. The integral polyamide insulation sleeve keeps the tab protected during routing and handling, reducing the risk of accidental shorts in panel and enclosure wiring. If you're specifying panel terminations for security enclosures, access control hardware, or structured wiring assemblies, this is the type of terminal that keeps a build clean and inspection-ready.
The EDNF14250FIMB-L (often searched as EDNF14250FIMB L) accepts the standard 0.250 x 0.032 inch male tab, which is the most common disconnect format in North American low-voltage hardware. Carton quantity is 500 units; package quantity is 50 — sized for project-scale pull quantities without overcommitting storage.
Key Features
- Integral Polyamide Insulation: Full-coverage nylon over the barrel and flag means the bare copper never exposes during panel dress-out. On high-density terminal blocks where adjacent conductors are close, that insulation eliminates the need for tape-over after termination — saves time and passes visual inspection cleanly.
- 16–14 AWG Wire Range: Covers the most common low-voltage control wire gauges used in access control, alarm panels, and power distribution sub-assemblies. A single SKU handles both 14 AWG power runs and 16 AWG signal leads, reducing the number of terminal SKUs you stock on the bench.
- 0.250 x 0.032 Tab Size: The industry-standard 0.250-inch (¼-inch) quick-disconnect tab fits the vast majority of North American relay contacts, solenoid terminals, and panel bus hardware. The 0.032-inch tab thickness confirms compatibility with standard receptacle terminals — no guesswork on mate fit.
- Tin (Étamé) Finish: Tin plating on the copper contact surface resists oxidation in enclosure environments where air circulation is limited. Compared to bare copper, tin-plated contacts maintain lower contact resistance over time — relevant when these are used on 12V or 24V control circuits where a few milliohms matter for relay pull-in voltage.
- UL and CSA Listed: Both UL and CSA marks mean this terminal meets North American electrical code requirements for panel and equipment wiring. On commercial or industrial jobs where the AHJ pulls the panel, having listed terminals avoids a code deficiency on termination hardware.
- Overall Length 0.91 in / Width 0.45 in (11.4 mm): Compact form factor keeps terminal density high in narrow DIN rail enclosures or tight terminal strips. At 11.4 mm wide, these fit standard panel layouts without crowding adjacent terminals.
- StrongHold™ Series — Crimp Tool Compatibility: Rated for use with Panduit CT-600-A, CT-1525, CT-2300/ST, and CT-2500/L crimping tools. Specifying the correct crimp tool is not optional — a mismatched tool produces a cold crimp that will fail pull-test. If your field team already runs one of these tools, the EDNF14250FIMB-L drops right into the existing workflow.
- Package Quantity 50 / Carton 500: Order in bags of 50 for small jobs or full cartons of 500 for panel shops. Neither quantity forces waste on small installs or under-orders on production runs.
Integration & Compatibility
The EDNF14250FIMB-L is a loose-piece terminal — it requires a separate crimp tool from the Panduit StrongHold™ tool line. Verified compatible tools include the CT-600-A, CT-1525, CT-2300/ST, and CT-2500/L. Do not substitute a generic ratchet crimper; the StrongHold insulated die set is matched to the barrel geometry to produce a gas-tight crimp without cracking the nylon sleeve.
Cross-reference part numbers for this terminal include 83-9921, FQN14M25X03D, and MTI14-250Q, which appear on competing manufacturer equivalents. If you're replacing a different brand's terminal mid-project, verify the tab size (0.250 x 0.032) and wire range (16–14 AWG) match your existing receptacle before substituting.
This terminal is appropriate for wire termination applications in security system panels, access control enclosures, and commercial electrical assemblies. For broader Panduit wiring and connectivity products, including cable ties, duct, and patch panels, the full catalog covers structured cabling infrastructure from tray to terminal. If you're specifying an enclosure build, pair these terminals with appropriately rated power supply hardware and cable management to keep panel dress-out consistent and inspection-ready.

Frequently Asked Questions
Q: What wire gauge range does the EDNF14250FIMB-L accept?
A: The EDNF14250FIMB-L is rated for 16–14 AWG wire. It covers both 14 AWG power leads and 16 AWG signal/control wiring in a single SKU.
Q: What crimp tools are compatible with the EDNF14250FIMB-L?
A: Panduit lists the CT-600-A, CT-1525, CT-2300/ST, and CT-2500/L as compatible crimping tools for this terminal. Using an unverified tool risks cold or damaged crimps — stick to the listed tool set.
Q: What is the tab size on the EDNF14250FIMB-L?
A: The male tab is 0.250 x 0.032 inches — the standard North American ¼-inch quick-disconnect size compatible with most relay contacts, solenoid terminals, and panel hardware using this tab format.
Q: Is the EDNF14250FIMB-L UL listed?
A: Yes. The EDNF14250FIMB-L meets both UL and CSA standards, making it appropriate for use in commercial and industrial panel wiring where listed terminals are required by code.
Q: What is the insulation material on the EDNF14250FIMB-L?
A: The insulation is integral polyamide (nylon), which provides full coverage of the barrel and flag. Polyamide insulation holds up in enclosure environments with limited airflow and resists cracking during crimp better than PVC alternatives.
Q: What are the cross-reference part numbers for the EDNF14250FIMB-L?
A: Known equivalent part numbers from competing manufacturers include 83-9921, FQN14M25X03D, and MTI14-250Q. Always verify tab size and AWG range before substituting.
The EDNF14250FIMB-L is the kind of terminal that gets specified once correctly and then forgotten about — which is exactly how it should be. The integral polyamide sleeve on this StrongHold™ disconnect is the detail that matters in dense panel builds: you crimp, route, and dress the wire without reaching for tape or heat shrink, and the visual stays clean through inspection. At 0.91 inches overall length and 11.4 mm wide, it fits tight terminal arrays without forcing spacing adjustments on adjacent conductors.
Technical Highlights:
- Tin-Plated Contact Surface: Tin finish resists oxidation in sealed enclosures where bare copper would tarnish over months. On 12V/24V relay circuits, oxidized contacts raise resistance enough to affect pull-in — tin plating keeps the interface stable over the installation's service life.
- 0.250 x 0.032 Tab Geometry: Matches the standard North American ¼-inch quick-disconnect receptacle used across relay blocks, solenoids, and bus hardware. At 0.032 inches thick, it mates with standard-force receptacles without over-spreading the contact spring — a detail that affects long-term retention force.
- UL and CSA Dual Listing: Both marks in a single terminal SKU means this part satisfies AHJ requirements on either side of the US/Canada border without sourcing a separate listed part for Canadian projects.
Deployment Considerations:
- Crimp tool selection is non-negotiable: the CT-600-A, CT-1525, CT-2300/ST, and CT-2500/L are the verified tools for this terminal. A mismatched die will either under-crimp (high resistance, pull-test failure) or crack the nylon sleeve, which voids the insulation integrity and the UL listing on that termination.
- Package quantity is 50 per bag, carton is 500. If you're running a multi-panel project with dozens of relay/solenoid terminations, order at the carton level — running out mid-panel and waiting on a resupply bag is avoidable with a simple count before mobilization.
The EDNF14250FIMB-L is the right spec for commercial security panel builds, access control enclosure terminations, and any low-voltage control assembly where a listed, fully insulated male disconnect is required and the 14–16 AWG range covers the wire schedule. It is not a field-improvisation terminal — it belongs in a planned, tool-crimped panel environment where the StrongHold tool set is already on the bench.
