The TE Connectivity Buchanan 282844-2 is a 2-position PCB terminal block with a 7.50 mm pitch, designed for side-entry (horizontal) wire termination. It uses a rising cage clamp mechanism — the screw pushes a clamp plate down onto the conductor, creating a gas-tight connection without damaging the wire. The green polyamide (PA66) housing is rated for 17.5 A at 300 V, and the M3 screw is torqued to 0.79 Nm (7.0 Lb-In). This block is intended for through-hole soldering on a PCB, and the side-entry orientation keeps the wiring parallel to the board — useful when vertical clearance is limited inside an enclosure.
The 7.50 mm pitch is wide enough to accommodate 12 AWG wire (the block accepts 12-30 AWG) while maintaining 300 V of creepage between adjacent positions. The 17.5 A rating is per position at the rated voltage — in practice, derate the current if the ambient temperature inside the enclosure exceeds 25 °C, or if multiple adjacent blocks are ganged without spacing. The rising cage clamp termination is field-friendly: strip the wire, insert, tighten the M3 screw to the specified torque, and the clamp holds the conductor without cold flow or loosening under thermal cycling.
Interlocking Side Feature and Ganging
This block includes an interlocking (side) feature, meaning multiple 282844-2 blocks can be snapped together side-by-side to create a multi-position assembly without extra brackets or jumpers. The interlock aligns the blocks and prevents them from separating during handling or vibration. For a build requiring more than 2 positions, order additional 282844-2 units and snap them together — no separate end covers are needed unless the assembly terminates at an open side.
