FAQs
For installation, ensure correct alignment of the 18-pin contact layout with the mating connector, use the 1/3 bayonet coupling for quick seating, and install with the straight backshell adaptor to simplify routing in tight panels. The solder cup contacts provide a robust field-termination method, but proper thermal relief and strain relief should be applied to maximize reliability in vibration-prone environments.
The 1/3 bayonet coupling enables fast, secure mating with positive locking, reducing misalignment risk and cycle time during assembly. It also allows easier disengagement in maintenance scenarios, supports vibration resistance, and minimizes wear on the contact interface, which translates to longer connector life and lower replacement costs in production lines and mobile equipment.
Yes. The connector is rated for operating from -40 °C to 125 °C, with cadmium plating and an aluminium shell that contribute to durability in extreme thermal cycles. When selecting for harsh environments, ensure cable insulation and mating components also meet the temperature range and that proper sealing (if required) is implemented for exposure to contaminants.
The 85100AC1418P50 is MIL-DTL-26482 SI qualified, indicating conformance to a stringent military interconnect standard. It also lists REACH compliance for environmental safety. These certifications help ensure traceability, supply chain reliability, and regulatory alignment for defense, aerospace, and industrial automation programs, reducing risk in regulated deployments.
The high-density 18-pin arrangement in a compact 48 mm footprint reduces panel real estate and wiring complexity, lowering assembly time and potential wiring faults. The robust solder Cup terminations and corrosion-resistant cadmium plating extend service life, decreasing maintenance intervals and replacing parts less frequently, which yields measurable total cost of ownership benefits over traditional interconnects.
