Binder has released the 823 and 824 series of cable connectors for use on the North American continent. The K- and L-coded M12 products particularly aim at power applications and feature screw clamp terminations. They satisfy the needs of the industry-relevant protection degree IP67, i.e. they are created to be dust-tight and protected against temporary submersion.

The K coding indicates five-pin connectors that are ideal for power supply in AC applications, including drives or frequency converters with up to 630VAC and up to 12A. DC compact drives, decentralised I/O modules and assorted other DC-powered automation components connected to fieldbus systems are amongst the target applications of the likewise five-pin connectors with L coding. They are created for rated voltages up to 63VDC and for rated currents up to 16A.

Electromechanical interfaces on control cabinets for the North American market need approvals in accordance with the UL 2237 and UL 2238 standards. While UL 2238 specifies cable assemblies and connectors for signal transmission, UL 2237 sets further conditions for the power segment, such as the power supply in drives. It comprises specifications for testing connectors, cables and cable glands, and safety elements.

The product series incorporate both male and female cables and angled connectors for rated voltages of 630VAC at rated currents of 12A (K-coding; pin count 4+PE) and 63VDC at 16A (L-coding; pin count 4+FE – functional earth), respectively. They feature M12x1 threads, 8mm to 13mm cable outlets and screw clamp terminals. To meet the requirements of UL 2237, the threaded ring is electrically connected to the PE contact.
