Panduit DNFR18-250FIB-L Right-Angle Female Disconnect, 22-18 AWG, Nylon, Pack of 50

Overview

The Panduit DNFR18-250FIB-L is a right-angle, fully-insulated female disconnect terminal from the Panduit Pan-Term™ wire termination line. Built for space-constrained panel and enclosure wiring where a straight-pull connector won't fit, this disconnect combines a tin-plated brass barrel with a red polyamide (nylon) sleeve to handle 22–18 AWG conductors (0.5–1.0 mm²) at up to 600 V — with both UL and CSA listing to back that rating. It arrives in a pack of 50, and carton quantity is 250, which fits volume panel-build workflows without constant reordering.

If you're routing wire through tight control panels, industrial enclosures, or access-control door hardware where terminal blocks sit close to sheet-metal flanges, the 90-degree orientation of the DNFR18-250FIB-L (often searched as DNFR18 250FIB L) keeps your loom flat and reduces stress on wire insulation at the termination point — a common source of premature failure in high-vibration installations.

Key Features

• Right-angle (RA) configuration: The 90-degree tab orientation lets you dress wire parallel to the mounting surface rather than pulling it perpendicular. In shallow enclosures and DIN-rail-packed panels, that difference means the difference between a clean loom and a pinched harness. Overall depth is 0.60″ (15.2 mm), so plan clearance accordingly.
• Tin-plated brass contact: Tin over brass resists oxidation at the mating interface without the cost premium of silver plating. In panel environments with humidity cycling or mild chemical exposure, this finish maintains low contact resistance over time — which matters on 22 AWG signal-level wiring where a milliohm of extra resistance shows up as a voltage drop at the load end.
• Vibration-resistant design: The crimped barrel with internal wire stop locks the conductor at the correct insertion depth so vibration doesn't back the wire out of the crimp. On equipment that sees motor-induced vibration — conveyors, HVAC handlers, compressor panels — this is the spec that prevents intermittent faults that are nearly impossible to chase after the panel is closed.
• Internal wire stop: The barrel includes a positive stop that controls insertion depth, ensuring every crimp lands in the same position. This reduces the chance of over-insertion (conductor contacts the tab without a proper crimp) or under-insertion (insulation enters the barrel). Both failure modes are hard to detect visually post-crimp — the stop eliminates them mechanically.
• Fully insulated nylon sleeve, 105 °C rated: The red polyamide insulation is rated to 105 °C continuous, which keeps it viable in enclosures near heat-generating components (drives, transformers). UL 94V-2/HB flammability rating means the sleeve won't propagate flame — required in UL-listed panel assemblies. Red color coding aligns with standard AWG 22–18 identification practice.
• Tool-free insertion and removal from the male tab: The disconnect slides onto and off a 6.3 × 0.8 mm male tab without tools. In field-service scenarios — swapping a faulty sensor or actuator without a crimper on the bench — this matters. The wire-to-terminal crimp is permanent; only the tab engagement is tool-free.
• 6.3 × 0.8 mm tab interface: This is the standard .250″ quick-disconnect tab size used on terminal blocks, relays, solenoids, and motor-drive accessories across the industry. Panduit lists compatibility with the CT-300-1 crimp tool; that tool is required to achieve rated crimp quality — hand-crimping this gauge is not a reliable alternative.
• UL 310 and CSA LR31212 listing, 600 V rated: Both UL (homologation UL 310, UL 20H3 E78522) and CSA (LR31212, C22.2 no. 153) certifications are on record. For panels that need to pass electrical inspection or meet NEC/CEC requirements, those listing numbers are directly verifiable — not just claimed. Rated to 600 V, covering both 120 V and 480 V branch circuits.
• Pack of 50, carton of 250: The 50-piece pack is sized for single-panel builds; the 250-piece carton suits production runs or stocking. No need to break a 1,000-piece reel for a 30-terminal job — the pack size matches typical panel-build quantities.

Integration & Compatibility

The DNFR18-250FIB-L mates with any standard .250″ (6.3 mm) quick-disconnect male tab — the same interface used on virtually all relay sockets, terminal block accessories, solenoid coils, and sensor pigtails in this wire gauge range. Competitor cross-references include 190060001, 19007-0001, S05360SF, and SO5360SF, which simplifies drop-in replacement sourcing when an existing panel uses another brand's terminals.

Conductor compatibility is 22–18 AWG (0.5–1.0 mm²) — a range that covers most 24 VDC control wiring, sensor runs, and low-voltage actuator feeds used in access control panels, intrusion panels, and building automation terminations. This gauge does not support 16 AWG or heavier power runs; use a larger frame terminal for those circuits.

Crimp tooling: Panduit lists the CT-300-1 as the correct crimp tool for this terminal. Using an uncalibrated or mismatched crimper risks an underformed barrel that passes a pull test at the bench but fails under vibration in the field.

The spec I keep coming back to on the DNFR18-250FIB-L is the right-angle geometry paired with the internal wire stop — not because they're flashy, but because in tight DIN-rail enclosures those two details together eliminate the two most common field failures I see on quick-disconnect terminations: pinched wire loom from straight-pull terminals fighting for clearance, and mis-crimped conductors where the wire never reached the barrel stop. Panduit engineered both out of the equation on this part.

Technical Highlights:

• 600 V dual-listed (UL 310 / CSA LR31212): Both listing numbers are on record and verifiable — not marketing language. For panels that need to pass AHJ inspection on 480 V circuits, this terminal covers you without needing a higher-voltage alternative.
• 105 °C / UL 94V-2 nylon sleeve: The polyamide insulation holds to 105 °C continuous, which matters in enclosures where a VFD or transformer is sharing the same cabinet. The flame rating means it won't become a propagation path in a fault event.
• 6.3 × 0.8 mm standard tab interface: Industry-standard tab size means this terminal drops onto virtually any relay socket, solenoid coil, or sensor pigtail tab without adapter hardware. Cross-references to four competitor part numbers (190060001, 19007-0001, S05360SF, SO5360SF) simplify retrofits on existing panels.

Deployment Considerations:

• Crimp tool matters here: Panduit specifies the CT-300-1 for this terminal. I've seen panels where an installer used a generic ratchet crimper on 22 AWG — the barrel looks closed but the conductor isn't fully seated. A barrel that fails a 20 lb pull test at 22 AWG tells you everything. Use the specified tool.
• The 0.60″ (15.2 mm) depth is the clearance dimension that bites integrators — it's the direction the terminal projects away from the tab. In enclosures with less than 20 mm of depth behind the terminal strip, you'll be stacking these against the back panel. Measure before you wire.

This terminal earns its place in access control panel builds, intrusion panel termination harnesses, and industrial control enclosures where 22–18 AWG control wiring meets solenoid outputs or relay coils in space-constrained layouts. It's not the right pick for 16 AWG power runs or open-face environments where the nylon sleeve could be snagged — but in a DIN-rail panel running 24 VDC sensor and actuator circuits, it's a well-specified, inspection-ready choice.
