Targeting rugged marine and other industrial applications, the XRC sealed circular connectors (plugs and receptacles) are now available in 18-shell/14-circuit and 24-shell/31-circuit sizes. In the 24-shell size, 31-circuit connectors have a wire seal imprinted, instead of embossed or engraved, allegedly making it easier to see and identify each circuit. A backshell is also available for use with the 24-shell size products. The backshells snap onto the XRC housing after terminal assembly for increased strain relief. Meeting IP67 standards, XRC plugs and receptacles protect against the ingress of dust, water, and other contaminants. Plugs feature a quick-disconnect bayonet latch and the overall connector features a grommet retainer with a lip for compatibility with backshell and over-molded applications. Plugs and receptacles are available in standard and reverse gender. MOLEX INC., Lisle, IL. (800) 786-6539.
