It features an arrangement of 10 size 16 socket contacts intended for a size 18 shell. The contacts are silver-plated with pre-tinned solder cups, and the hard dielectric insert is made of diallyl-phthalate. These connectors operate over a temperature range of -55°C to +125°C and utilize a threaded coupling mechanism for secure mating. As part of the durable and field-proven 97 Series, this insert is ideal for automotive, robotics, and machine tool applications.
