Used in rugged and harsh environments, rectangular connectors offer design flexibility and ease of use as their advantage over other connector shapes.

Rectangular connectors are most often used in industrial automation, robotics, machine building, transportation-rail, and power creation.

Today, we are taking a deeper dive into Radiall Quickmate Connectors.

Radiall Quickmate Connectors

Quickmate, a range of quick mating connectors were developed for the ease of wiring in cable-to-cable and PCB-to-cable applications.

These connectors have a unique slide-lock system that features one finger mating—in a snap (Radiall Touch). Quickmate connectors offer designed cost-effective solutions for any industry.

Applicable industries: Aerospace, Defense, Industrial, Medical, Space, Telecom, Test, and Measurement.
