Sealed Mini-USB connectors

23 November 2011 Interconnection

CONEC has expanded its bayonet-locking and water-resistant series of connectors with a Mini-USB connector compliant with USB 2.0 specifications. The new connector provides design engineers with a highly reliable option for harsh environments. It is part of CONEC’s expansive IP67-rated family widely used in industrial production, food/beverage, chemical controllers process, outdoor wireless, Bluetooth adapters, diagnostic and test instruments, oil/gas and factory automation applications.

The water-resistant Mini-USB products feature robust internal components housed in black plastic with a bayonet locking ring. Compared to threaded connections, the bayonet feature ensures fast assembly and provides an audible ‘snap’ indicating the connectors are securely mated and therefore watertight. The bayonet feature is compact at just 12 mm diameter, and vibration resistant. The interface meets IP67 requirements when a mating connector is inserted or when covered with a secured protective cap.

The connector contacts are phosphor bronze and gold plated with a contact resistance rated at a maximum 50 mΩ and insulation resistance of 100 mΩ. Current ratings are 1 A maximum at 25°C, and operating temperature ranges from -40°C to +80°C.

The product line includes a panel receptacle which may be PCB mounted or used with a flex circuit, protective caps and pre-terminated jumper cables with an overmoulded Mini-USB type B plug. The patch cables are available in various lengths (2, 3 and 5 metre standard lengths) and are terminated to an overmoulded USB type A standard plug.
