The TE Connectivity Buchanan 2-282836-1 is a 20-position, single-level PCB-mount terminal block on a 0.197" (5.00 mm) pitch. It terminates wires from 16-30 AWG using a screw-driven rising cage clamp — the clamp lifts inside the housing to pinch the wire against the current bar, so the screw never twists the conductor. Rated for 13.5 A at 300 V, it sits in the Buchanan series as a through-hole, side-entry (horizontal with board) block, colour green.
How the Rising Cage Clamp Termination Works
Strip the wire to the recommended length, insert it into the clamp opening, and tighten the M3 screw to 0.68 Nm (6 Lb-In). The rising cage clamp lifts upward, trapping the wire between the cage and the conductor bar. This design avoids the strand damage a traditional screw-and-clamp can cause and gives a gas-tight connection. The brass screw and clamp are both nickel-plated; the contact bar is tin-plated brass. The interlocking (side) feature lets you link multiple blocks side-by-side without a separate jumper — the housing keys into the next block.
What the 13.5 A and 300 V Ratings Mean for Your Circuit
13.5 A per position is a power-class rating — this block is meant for distribution and control circuits, not signal-level lines. The single-level, 20-position layout fills a full row on the PCB; if you need fewer positions, the interlocking side feature lets you break the block into smaller sections or add more.
