3.81 mm Pitch, 2-Position Plug for Field Wiring
The 284511-2 is a 2-position plug from TE's Buchanan series — a free-hanging female socket block with a 0.150" (3.81 mm) pitch. It terminates individual wires via a screw rising cage clamp, accepting 14-30 AWG (0.05-2 mm²) with a 5-6 mm strip length. The 11 A / 300 V rating (per UL) suits it for control cabinets, sensors, and low-power distribution where each circuit needs a field-serviceable screw termination. The mating flange and M2 screw secure the plug to its header, preventing pull-out in moderate vibration.
Screw Rising Cage Clamp — Torque and Wire Prep
Phosphor bronze contact material with tin mating finish provides adequate conductivity for the 11 A rating in a controlled environment. For repeated mating cycles (e.g., during panel commissioning), tin contacts are rated for moderate duty — not for frequent field disconnect/reconnect where gold plating would be specified.
Active Lifecycle and Sourcing
This plug mates with a Buchanan 3.81 mm pitch header (base product number 284511). The mating flange on the plug aligns with the header's locking tabs. Within the series, the 2-position variant is the smallest circuit count — larger versions go up to 24 positions at the same pitch. For a 2-circuit termination point, this plug is the compact, field-wireable choice.
