Mini-Fit Jr. Backshells

Molex Mini-Fit Jr. Backshells are hermaphroditic strain relievers made in 2, 4, 6, 8, 10, and 12 circuits. These backshells increase the strain relief produced in the wire during assembly and reduce the power loss in the Mini-Fit connector system. Molex Mini-Fit Jr. Backshells accommodate the dual row without panel mount versions of Mini-Fit plug and receptacle housings. These backshells are nylon made and accept the wide ranges of 18, 20, and 22 American Wire Gauge (AWG) of UL-1015 and UL-1569 styles.
