4-Position 5.00 mm Plug for Panel Wiring
The 284046-4 is a 4-position, single-level plug from TE's Buchanan series, pitched at 0.197" (5.00 mm) — a common spacing for industrial control terminal blocks. It's a free-hanging (in-line) female socket plug with 90° wire entry, meaning the wires exit perpendicular to the mating axis, useful for routing along a panel or enclosure wall. The green housing is standard for ground/neutral identification in many European-style terminal block schemes.
Screw Rising Cage Clamp Termination
Termination is via a screw-driven rising cage clamp — the screw (M3) pushes a clamp plate up against the wire, gripping it against the contact. The specified torque is 0.79 Nm (7.0 Lb-In); overtightening can strip the cage or damage the conductor. Accepts wire from 12-30 AWG (0.05-3 mm²) with a strip length of 6-7.5 mm. The retention latches on the wire side hold the plug in the mating header, preventing accidental disconnection under vibration.
