2-Position Header for Wire-to-Board in Tight Spaces
The 172732-2: Shrouding is limited to one wall — the header has a single shroud on one side of the pin row, leaving the other three sides open. This saves board space but means the mating connector must be aligned carefully to avoid stubbing on the exposed pins.
Voltage and Current — What the Ratings Mean
Rated 250 VAC and 350 VDC — the DC ceiling is higher because the creepage path under steady DC stress is less prone to tracking than under AC. This covers both line-voltage AC and typical 24–48 VDC control circuits. For a given wire gauge, derate per the temperature rise curve in the full product drawing. Operating temperature range is -20°C to 95°C, which suits indoor equipment and climate-controlled cabinets but not engine compartments or outdoor direct-sun enclosures without additional derating.
Contact length - post is 0.142" (3.60 mm), which determines the PCB thickness range the header can accommodate. Overall contact length is 0.551" (14.00 mm), with the mating pin length at 0.295" (7.49 mm).
ROHS3 compliant and packaged in bulk — no tape-and-reel, so it ships loose in a bag or tube. Suitable for hand-load or low-volume assembly.
How It Compares to Similar Headers
Compared to the 1-292164-1 (CT series, 2.00 mm pitch, 11 positions, right-angle, 4-wall shrouded, detent lock), the 172732-2 has a wider 2.50 mm pitch, fewer positions, vertical orientation, and single-wall shrouding — it is a simpler, lower-density part for basic 2-wire connections. The 1376366-8 (.025 series, 2.20 mm pitch, 8 positions, right-angle, 4-wall shrouded, rated 5 A) offers more positions and a fixed current rating, but the 172732-2's vertical orientation and latch holder suit a different board layout and fastening requirement.
