PCB Terminal Block for Power-Level Wiring
The TE Connectivity Buchanan 282837-2 is a 2-position PCB-mount terminal block from the Buchanan series, designed for power-level wire termination on a board. The green housing follows the convention for ground/earth terminal blocks in many panel layouts, though the buyer should confirm their own color code. Side interlocking lets multiple 2-position blocks snap together into a longer strip, saving a separate jumper order when the board needs more than two circuits.
Wiring and Termination — Torque Matters
Wire termination is a screw-rising cage clamp — the screw lifts a clamp plate that traps the stripped wire against the current bar. The specified torque is 0.68 Nm (6 Lb-In), which is tight enough for a gas-tight connection on 16 AWG but not so high that it strips the M3 brass screw. The clamp plate is brass with nickel plating, and the contact bar is brass with tin plating — tin is adequate for the moderate mating cycle of a terminal block that gets wired once and left. Wire range 16-28 AWG covers both the heavy power feed and the smaller signal return.
Board Mounting and Orientation
Mounting is through-hole, with the wire entry oriented horizontally with the board — wires enter parallel to the PCB surface, not straight down. This orientation suits boards mounted in enclosures where the wire bundle comes in from the side and the board sits flat. The single-level design keeps the block low-profile; the side interlocking feature allows stacking additional 2-position blocks end-to-end without extra hardware, useful when the BOM calls for multiple isolated circuits on the same pitch.
The base product number is 282837, so a search for that base will surface other position counts in the same family if the BOM needs a different circuit count.
