Panduit EDNF18-187MB-Q Nylon-Insulated Male Disconnect Terminal

The Panduit EDNF18-187MB-Q is a StrongHold™ nylon-insulated male disconnects terminal rated for 22–16 AWG wire, designed for quick-connect wiring in control panels, security system enclosures, and industrial automation assemblies. Sold in packs of 25, this tin-plated, 0.187" × 0.032" tab terminal meets cULus E78522 standards — a real requirement for listed panel builds where inspectors check every termination. If you need a reliable, inspectable crimp termination that won't pull loose under vibration or repeated disconnect cycles, this is the hardware to spec.

Key Features

• 22–16 AWG Wire Range: Covers the wire gauges most common in low-voltage security and control wiring — alarm loops, panel power distribution, sensor feeds — without needing a separate terminal for each gauge. One SKU handles a practical range.
• 0.187" × 0.032" Male Tab: The 0.187" tab width (4.8mm) is the standard quick-disconnect size used across the security and industrial connector ecosystem. Female receptacles from virtually every panel and device connector strip will mate correctly. At 0.79" overall length, the terminal fits in tight enclosures without clearance issues.
• Nylon Insulation (StrongHold™): The over-molded nylon sleeve protects the crimp barrel from incidental contact and provides color-coding visibility for wire-gauge confirmation during install and future service calls. Nylon holds up to the temperature swings common in outdoor enclosures and unheated equipment rooms.
• Tin-Plated (Estañado) Contact: Tin plating resists oxidation at the mating interface — an important detail in humid or coastal environments where bare copper contacts corrode and increase resistance over time. Consistent contact resistance means reliable circuit continuity for monitored alarm circuits.
• cULus Listed (E78522): Carries UL component recognition under file E78522, satisfying the UL listing requirements for control panels and fire alarm systems. If the AHJ or your integrator agreement requires listed terminations, this qualification is non-negotiable — and it's already here.
• Pack of 25 (MOQ 10 Packs): The 25-piece package is sized for project-level termination work rather than one-off repairs. Carton quantity of 20,000 means availability for large contract installs without lead-time risk.
• Compatible with KST2000C Crimp Tool: Panduit specifies this terminal for use with the KST2000C crimper, ensuring the barrel is fully captured and mechanically correct every time — eliminating the variability of undersized or non-matched tooling.

Integration & Compatibility

The EDNF18-187MB-Q (often searched as EDNF18 187MB Q) mates with standard 0.187" female quick-disconnect receptacles widely used in control panels, alarm system boards, and electrified hardware. Cross-reference competitor part numbers MTI18-187Q and QN18M18X02D if sourcing from multiple channels. For wire termination projects requiring a higher-volume crimp tool, pair with the KST2000C (sold separately, not through Panduit direct). For full Panduit wiring infrastructure consistency, combine with Panduit cable ties, duct, and patch panels on the same panel build.

Frequently Asked Questions

Q: What wire gauges does the EDNF18-187MB-Q accept?

A: This terminal is rated for 22–16 AWG wire, covering the most common low-voltage control and alarm wiring gauges used in security and industrial panels.

Q: Is the EDNF18-187MB-Q UL listed?

A: Yes. It meets cULus requirements under file E78522, making it suitable for use in UL-listed control panel assemblies and inspected fire alarm systems.

Q: What is the tab size on this disconnect terminal?

A: The male tab measures 0.187" × 0.032" — the standard quick-disconnect tab size compatible with the majority of female receptacle connectors used in security and automation hardware.

Q: What crimp tool is recommended for the EDNF18-187MB-Q?

A: Panduit specifies the KST2000C crimping tool for use with this terminal. Note that the KST2000C is not sold through Panduit direct channels.

Q: How many terminals come in one package?

A: Each package contains 25 terminals, with a minimum order quantity of 10 packages. Carton quantity is 20,000 for large-volume procurement.

The EDNF18-187MB-Q sits in a part of the BOM that integrators rarely think hard about — until a terminal fails QC or an AHJ kicks back a panel. The cULus E78522 listing is the key spec here: on listed alarm or control panel builds, every termination component needs traceable certification, and this terminal delivers it without any special sourcing gymnastics.

Technical Highlights:

• 0.187" × 0.032" Tab Geometry: Exact match to the industry-standard quick-disconnect footprint — female receptacles on virtually every alarm board, door controller, and relay module will mate without adapter hardware.
• 22–16 AWG Barrel: One terminal handles both 22 AWG sensor loops and 16 AWG power runs in the same panel, reducing SKU count on the BOM and eliminating mixed-terminal errors during harness assembly.
• Tin-Plated Contact Surface: Oxidation resistance matters in enclosures with thermal cycling. Tin plating maintains consistent contact resistance across the service life of the installation — relevant for supervised alarm circuits where resistance changes trigger trouble conditions.

Deployment Considerations:

• Confirm your female receptacle accepts a 0.032" blade thickness — some legacy connectors are spec'd for 0.020" blades and will have loose retention with the 0.187" × 0.032" tab.
• The KST2000C crimp tool is specified by Panduit for this terminal and is not sold through Panduit direct; verify tool availability separately before committing this part to a large panel run.

Best fit for security integrators wiring electrified door hardware panels, fire alarm control panels, or any listed enclosure build where the AHJ will inspect termination certifications — the E78522 cULus listing removes any question at inspection.
