The 97-16S-1P(431) is a single-contact socket insert arrangement for the Amphenol 97 Series standard cylindrical connectors with solder contacts. This connector features a #16 AWG contact size and is designed for INST. (instrumentation) service applications with a limiting operating voltage of 250V DC / 200V AC at sea level. The connector utilizes a threaded coupling mechanism with hard dielectric inserts and non-rotating contacts, operating reliably across a temperature range of -55°C to +125°C. The (431) suffix indicates a specific shell finish option. This connector is UL recognized (File E115497) and CSA certified (File LR69183), making it suitable for industrial applications requiring durable, field-proven cylindrical connector solutions with single-contact configurations.
