Terminal Block for PCB Mount — 9 Positions, 3.81 mm Pitch
The TE Connectivity Buchanan 284392-9 is a 9-position, single-level terminal block designed for through-hole PCB mounting. It uses a screw - rising cage clamp wire termination, accepting 14-30 AWG wire. The 0.150" (3.81mm) pitch gives you a compact footprint for routing multiple circuits on a control board or power distribution PCB. Rated 12 A at 300 V, it handles typical industrial signal and low-power loads without derating concerns at room ambient. The green housing is polyamide (PA66) — a standard flame-retardant material for equipment inside an enclosure.
Wiring and Termination — Screw Cage Clamp
The rising cage clamp mechanism pulls the conductor against a brass, nickel-plated clamp plate as you tighten the M3 screw. The specified torque is 0.25 Nm (2.2 Lb-In) — enough to secure stranded or solid wire without crushing the strands. The clamp material is brass with nickel plating, which resists corrosion in humid cabinet environments. The contact material is brass with tin plating — adequate for the current rating and typical cycle life in a fixed installation.
Ganging and Orientation — Side Interlocking
The side interlocking feature lets you snap multiple 284392-9 blocks together side-by-side to build a wider terminal strip without extra brackets or end covers. The single-level design means all nine terminations are in one row, simplifying wiring access and labelling.
