12-Position Terminal Block Plug – What It Connects and Where It Goes
The 1-796861-2 is a 12-position plug with female sockets from the TE Connectivity Buchanan series, designed for free-hanging (in-line) installation. It mates with a matching header (typically a Buchanan or Eurostyle terminal block header) to create a field-wireable power or signal connection in industrial control panels, HVAC equipment, and building automation. The 5.08 mm pitch is a standard spacing for terminal blocks, matching many common PCB headers. The 15 A current rating at 300 V UL means this plug can handle moderate power distribution within an enclosure — think 24 VDC sensor power or 120 VAC relay outputs. The green housing colour is typical for the Buchanan series, aiding visual identification in a crowded cabinet. The mating flange and retention latches (non-wire side) lock the plug to the header, preventing accidental disconnection under vibration.
Termination and Wiring – Screw Rising Cage Clamp
The wire strip length is 6-7.5 mm — a standard strip for terminal blocks. The 270° wire entry angle means the wire enters from the side rather than straight in, which can simplify routing in tight enclosures.
The base product number is 796861, which can be used to search for related accessories or mating headers in the Buchanan series.
