The 97-20-27S(431) is a standard cylindrical connector from the Amphenol 97 series, designed for general-duty applications requiring a durable and cost-effective interconnection. It features a size 20 shell with the 20-27 insert arrangement, which provides 14 size 16 socket contacts for solder termination. This connector has a threaded coupling mechanism for secure mating, single key/keyway polarization to prevent mismating, and hard diallyl-phthalate inserts. Constructed from high-grade aluminum alloy with an olive drab chromate finish, it operates over a temperature range of –55°C to +125°C. Its field-proven design makes it suitable for use in industries such as robotics, machine tools, and welding.
