Panduit DV18-250P-MYY Pan-Term Piggyback Disconnect Terminal
The Panduit DV18-250P-MYY is a vibration-resistant piggyback disconnect terminal designed for reliable multi-point power distribution and control wiring in commercial security, access control, and industrial equipment installations. This 22-18 AWG terminal features a tin-plated steel barrel with red vinyl insulation support, accepting 0.250 × 0.032" (6.3 × 0.8 mm) male tabs for tool-free connection and disconnection. Bulk-packaged in boxes of 1,000 for volume integration work.

The DV18-250P-MYY terminal solves a common problem in access control and security system power distribution: maintaining reliable electrical connections in equipment subjected to door slams, HVAC vibration, or transportation shock. The terminal's defining feature is its insulation support barrel—a crimped metal sleeve that grips both the stripped conductor and the wire's vinyl jacket. This dual-grip design prevents the conductor from flexing at the crimp point, which is the typical failure mode for standard crimp terminals in vibration-prone installations. The 22-18 AWG wire range covers most low-voltage security and control wiring (18/2, 22/4 access control cable, relay coil leads), while the tin-plated finish prevents galvanic corrosion when mated with brass or steel male tabs in mixed-metal panels.
Piggyback (or "stackable") terminals are essential for modular equipment design—each terminal features both a female receptacle for mating with a male tab and a male tab extension for stacking additional terminals. This configuration allows integrators to add auxiliary power taps, indicator circuits, or monitoring points to an existing relay or power bus without re-terminating the original connection. The 0.250" tab width is the industry-standard size for control relays, power supplies, and terminal blocks in NEMA enclosures. The tool-free disconnect capability reduces service time during troubleshooting: technicians can pull a piggyback terminal from its mating tab by hand, verify continuity or swap components, and reconnect without crimpers or wire strippers. Bulk packaging in 1,000-piece boxes supports large commercial projects (multi-door access control systems, elevator recall panels, fire alarm interface modules) where terminal cost per point matters and inventory management favors single-SKU purchasing.
The UL 94V-2 flammability rating indicates the red vinyl insulation will self-extinguish within 30 seconds when exposed to open flame, a baseline requirement for components installed inside listed electrical enclosures. The 300V rating provides adequate margin for 120VAC relay coils and 24VDC power distribution (common in access control and intrusion systems), though the terminal is typically deployed in sub-50V applications where wire gauge and crimp integrity are the limiting factors. The terminal is compatible with Panduit's pneumatic and manual crimping tools—using the correct crimp die (typically the red 22-18 AWG nest) ensures the insulation support barrel compresses uniformly around the wire jacket, maintaining the vibration-resistant seal. This terminal fits projects requiring UL-recognized components, field-serviceable connections, and deterministic performance in mechanically harsh environments—elevator machine rooms, rooftop HVAC equipment, vehicle fleet access gates.
