The housing carries glow wire compliance, which means the PA66 material is formulated to self-extinguish under the glow wire test per IEC 60695-2-11. This is a requirement for appliances, HVAC, and lighting fixtures where the connector must not propagate a fire from a hot component. This combination of glow wire and sealing makes the 2321926-5 suited for white goods, industrial controls, and automotive interior harnesses where both flame resistance and environmental protection are specified.
Mounting and Termination — Panel Snap-In and Crimp Contacts
The panel cutout must match the SDL 2.5 receptacle footprint; the snap-in retention holds the housing rigid during contact insertion and mating. The tab-type contacts — male terminals — mate with the female socket contacts in the SDL 2.5 plug housing. The natural colour PA66 housing is the standard for the series, with no colour-coding for keying; the locking ramp provides the polarisation.
How It Compares to Other SDL Series Housings
The closest peer in the evidence is the 1-1703532-1, a 2-position plug from the same SDL family at 9.50 mm pitch, also sealed with a locking ramp but free-hanging rather than panel-mount. The 5-position count versus 2 positions is the primary selection difference — the 2321926-5 serves a 5-circuit harness position where the 1-1703532-1 is for a 2-circuit line.
