These caps for push-pull connectors, when mated to a male or female connector, will provide IP67-rated environmental protection. The caps make the push-pull connectors ideal for use in commercial and industrial fields. The cap is designed to provide an IP67-rated environmental protection from liquids and debris while the connector is detached from its mating connector. Each cap is made of brass, which fits securely to the push-pull connector or receptacle, and attaches to the cable or panel via a polyurethane rubber strap to avoid any loss of parts. The new protective caps are available for male and female field-attachable connectors and panel-mount receptacles.
