The TE 4-2208157-1 is a 4-position, 2-row receptacle housing from the Heavy Duty Sealed Connector Series, MCP 1.5K/5.8. The blue, glass-filled PBT housing carries an IP67/IP69K rating, meaning it seals against dust, temporary immersion, and high-pressure, high-temperature washdown — typical for underhood automotive, off-highway equipment, and industrial washdown zones.
Four positions in two rows — the 4-2208157-1 mates with a 4-circuit male header in the same MCP 1.5K/5.8 series. The free-hanging (in-line) mounting suits harness-to-device connections where the housing floats with the wire bundle. The slide-on latch engages without tools and holds under vibration; no threaded coupling to torque. The blue colour is a visual key — it distinguishes this housing from natural or black variants in the same family, reducing mis-mate risk on the line. The IP67/IP69K rating is the headline feature: IP67 guarantees dust-tight and temporary immersion to 1 m for 30 minutes; IP69K adds resistance to 80°C water at 80-100 bar from close range — the washdown standard for food processing and heavy-duty vehicle underbodies. The -40°C to 140°C range means the housing survives cold starts and exhaust-adjacent heat without cracking or softening.
