12-Circuit Receptacle Housing for Dynamic D-1200 Wire-to-Board Systems
The TE Connectivity 1-1827864-6 is a 12-position receptacle housing from the Dynamic D-1200 series, designed for wire-to-board interconnect in industrial and automation equipment. It carries a 2.50 mm pitch and dual-row layout with a 3.30 mm row spacing, giving the board layout engineer a compact but serviceable footprint for a 12-circuit harness. The housing accepts female socket crimp terminals (sold separately) and terminates via standard crimp tooling, making it a field-replaceable connector for panel wiring or machine I/O.
What the 2.50 mm Pitch and Polarizing Key Mean for the Fit
The 2.50 mm pitch is the defining board footprint dimension — it sets the header pin spacing and the PCB drill pattern. At this pitch, the connector fits standard Dynamic D-1200 headers without forcing a dense routing grid. The polarizing key prevents a 12-circuit plug from being inserted into a mismatched header in a multi-connector harness, which saves a field service call when the harness is swapped. The latch lock provides an audible click when fully mated, confirming positive retention under vibration in a control cabinet or on a moving machine axis.
Mating Half and Termination
The 1-1827864-6 mates with the corresponding Dynamic D-1200 series header (same pitch and row count). Termination is crimp-style: the female socket contacts are inserted into the housing cavities and retained by the latch lock. The housing is free-hanging (in-line), so it is suited for harness assemblies that plug into a board-mounted header rather than being soldered directly to the PCB.
