10-Position Receptacle Housing for 3.50 mm Power Interconnects
It carries a 3.50 mm pitch and two rows spaced at 4.60 mm, giving enough room between circuits for the current rating this family supports. Glow wire compliance per IEC 60335-1 is built in, which matters for appliances and industrial equipment that must pass a glow-wire ignition test. A Terminal Position Lock (TPA) feature is integrated into the housing — it secures each crimped terminal in its cavity so a partially seated contact cannot back out during harness assembly or field service.
To build a finished wire harness you need the matching Ultra-Fit crimp terminals (female socket contacts, sold separately) and the correct header. The TPA (Terminal Position Lock) is a secondary retention feature molded into the housing — after you insert the crimped terminal, you push the TPA forward to lock the contact in place. It is a visual and tactile check that every terminal is fully seated before the connector is mated.
Glow wire compliance (IEC 60335-1) is a regulatory requirement for connectors inside household appliances and similar equipment that must not ignite under a glowing-element fault. The PA housing material is rated for this test, so the connector can be specified into a product that needs a glow-wire-rated bill of materials. The TPA (Terminal Position Lock) is a molded feature on the housing that slides over the terminal retention lances after crimp insertion. It prevents the contact from backing out if the wire is pulled — a common failure mode in high-vibration environments like industrial machinery or automotive underhood harnesses. Together, these two features make the 1722584110 suitable for applications where both safety certification and mechanical reliability are required.
