Panduit EDV18-250M-Q StrongHold™ Male Disconnect Terminal

The Panduit EDV18-250M-Q delivers field-serviceable wiring connections for access control panels, security system enclosures, and low-voltage control circuits where quick disconnect capability matters. This StrongHold™ male disconnect terminal handles 22-18 AWG wire with a 0.250 × 0.032" tab interface, combining tin-plated copper construction with vinyl barrel insulation for corrosion resistance and electrical isolation. cULus listed under E78522, these terminals meet NEC and CEC requirements for low-voltage control wiring in commercial security installations.

Key Features

22-18 AWG wire range accommodates standard control and signal wiring

0.250 × 0.032" male tab fits industry-standard quick-disconnect receptacles

Tin-plated copper contact surface resists oxidation in enclosures and plenum spaces

Vinyl barrel insulation rated for 600V, color-coded for wire gauge identification

cULus listed (E78522) for installation authority compliance

StrongHold™ crimp barrel design provides gas-tight mechanical and electrical connection

Compatible with Panduit CT-1525, CT-2300/ST, and CT-2500/L crimping tools

25-piece package supports typical access control panel or small enclosure build

The StrongHold crimp barrel uses a serrated interior surface and mechanical geometry engineered to cold-weld stranded copper conductors during crimping, creating a gas-tight bond that resists vibration loosening and thermal cycling. The vinyl insulation extends support to the wire jacket transition point, reducing stress concentration that causes conductor fatigue in frequently opened enclosures. Tin plating on the contact tongue maintains low contact resistance across the temperature and humidity swings common in non-climate-controlled equipment rooms and outdoor-rated NEMA enclosures. The 0.250" tab width is the industry-standard size for panel-mount components including relays, terminal blocks, power supplies, and lock control boards used in access control and intrusion systems.

Deploy these terminals for wiring connections that must be field-serviceable without cutting wire—door position switches, request-to-exit sensors, auxiliary relay outputs, and power distribution to access readers. The quick-disconnect design lets technicians swap failed components or troubleshoot circuits without decommissioning entire wire runs, a critical advantage in retrofit projects where pulling new cable through finished walls isn't viable. Proper crimping requires Panduit's ratcheting tools (CT-1525, CT-2300/ST, CT-2500/L), which apply controlled six-point compression and won't release until the crimp cycle completes—hand crimpers and generic tools undercompress the barrel, leading to high-resistance joints that fail under load. The 22-18 AWG range covers the wire gauges specified for most manufacturer-supplied pigtails and field-run low-voltage control circuits; verify wire gauge via jacket markings or a wire stripper gauge before crimping.

cULus listing under file E78522 confirms these terminals meet UL 310 (electrical quick-connect terminals) and CSA C22.2 standards for use in Listed control panels and fire alarm systems—required for installations subject to inspection by AHJs enforcing NEC Article 725 (Class 2 and Class 3 circuits). Tin plating provides the corrosion resistance needed in security enclosures where dissimilar metals, condensation from temperature swings, and exposure to concrete dust or coastal salt air would corrode bare copper contacts within months. This 25-piece package aligns with the connection count in typical single-door access control installations or small intrusion panel builds; carton quantity is 250 pieces for integrators running multi-door projects or stocking service van inventory.
