The TE Connectivity Buchanan 284415-5 is a 5-position, single-level PCB terminal block with a 0.150" (3.81mm) pitch, designed for vertical wire entry relative to the board. It uses a screw-driven rising cage clamp termination — the screw tightens a brass-nickel plated clamp that pulls the wire against a tin-plated brass contact bar, giving a gas-tight connection on stranded or solid wire from 12 to 30 AWG.
Wiring and torque — what the screw clamp needs
The M3 screw is specified to 0.25 Nm (2.2 Lb-In) — that is the torque that seats the rising cage clamp without stripping the brass-nickel screw or deforming the conductor. A quarter-turn past finger-tight is about right; a power driver on this small a thread risks over-torque. The 12-30 AWG range means the same block takes a 12 AWG power feed and a 30 AWG thermocouple or signal wire, which simplifies panel BOMs.
Side interlocking — ganging without extra hardware
The side interlocking feature lets multiple 284415-5 blocks snap together side-by-side to build a multi-position strip of any length, sharing the same 3.81 mm pitch. No separate end plates or bridging clips are required for mechanical assembly — the interlock keeps the row aligned during soldering and in service.
