3.50 mm pitch, 2-position plug for control wiring
The 284510-2 is a 2-position plug from the TE Buchanan series, terminated with a rising cage clamp screw — the standard field-wiring interface for industrial terminal blocks. The 0.138" (3.50 mm) pitch mates with the matching Buchanan header, and the free-hanging (in-line) mount lets it land on a cable bundle without a PCB footprint.
Screw clamp termination and wire entry
The insulation height is 0.437" (11.10 mm), which sets the clearance to adjacent components on the header side.
Note: this part is RoHS non-compliant per the ledger entry. If your BOM requires RoHS, verify the exemption or look for a RoHS-compliant variant in the Buchanan series.
