A circular connector product literally cuts corners, decreasing the diameter of the receptacle to meet spatial demands — particularly in low pin-count designs. Its cylindrical shape also provides exceptional terminal strength and a more streamlined fit, making circular connectors the preferred choice for applications involving a high potential for mechanical turbulence or impact damage.
Take food and beverage manufacturing, for example, where equipment must frequently endure high-pressure wash-downs and sterilization. Rectangular connectors (especially when configured side-by-side in close proximity) create crevices that are susceptible to debris and moisture. Without a proper seal, this can lead to oxidation, poor connectivity and cable failure.
With their sleek design and secure mechanical couplings, circular connectors can be configured to achieve exceptional IP ratings and offer better run-off, reducing the risk of corrosion, hygiene and reliability issues that can result.
