The TE Connectivity Buchanan 1-284392-2 is a 12-position, single-level PCB terminal block on a 0.150" (3.81mm) pitch. It is a side-entry (horizontal to board) screw clamp design, meant for terminating individual wires directly to a printed circuit board in control panels, power supplies, and industrial equipment.
Sizing the Wire and Setting the Torque
The rising cage clamp accepts 14 to 30 AWG wire — solid or stranded — and the M3 screw is torqued to 0.25 Nm (2.2 Lb-In). The brass, nickel-plated clamp and screw resist corrosion in mildly humid cabinet environments.
Power Handling and Board Layout
Rated 12 A per position at 300 V, this block suits low-to-moderate power distribution on a PCB — think terminal strips for sensors, relays, or small motor drives. The through-hole mounting provides a solid mechanical anchor; the horizontal wire entry keeps the overall height low, useful when the board sits in a shallow enclosure.
