Product details

5-Position PCB Terminal Block with Rising Cage Clamp

It uses a screw-driven rising cage clamp to terminate 16-28 AWG wire, with the wire entry oriented horizontally (parallel to the board). The 0.138" (3.50mm) pitch gives it a compact footprint for a 5-circuit power or signal distribution point on a PCB, while the green polyamide housing provides a visual cue often used for ground or chassis connections.

Rated Load and Wire Fit

The 16-28 AWG wire range covers solid and stranded conductors — the rising cage clamp presses the wire against the current bar without damaging fine strands. The copper alloy contacts are tin-plated, which is standard for stationary terminations where frequent reconnection isn't needed.

Board Layout and Orientation

Through-hole mounting with a horizontal wire entry means the wires run parallel to the PCB surface — useful when clearance above the board is tight. The 3.50mm pitch is a common European spacing; the 5-position block spans about 17.5 mm of board edge. No board lock or additional retention is specified — the solder joints carry the mechanical load, so the PCB footprint should include adequate pad and hole size per the manufacturer's drawing.

Frequently asked questions
