Use in control cabinets for this market requires specific testing and certification of the components. In the case of power applications, they are subject to the UL 2237 standard. Both the 823 and 824 series have been developed according to this standard.
The K- and L-coded M12 products are intended for power applications and feature screw clamp terminations. They meet the requirements of the industry-relevant protection degree IP67, i.e. they are designed to be dust-tight and protected against temporary submersion.
In industrial automation, the transmission of high electrical power via compact M12 components has become a fundamental requirement. The K coding indicates 5-pin connectors that are particularly suitable for power supply in AC applications, such as drives or frequency converters, with up to 630 V(AC) and up to 12 A. DC compact drives, decentralised I/O modules and various other DC-powered automation components connected to fieldbus systems are among the target applications of the likewise 5-pin connectors with L coding. They are designed for rated voltages up to 63 V(DC) and for rated currents up to 16 A.
The binder product series 823 and 824 include both male and female cable and angled connectors for rated voltages of 630 V(AC) at rated currents of 12 A (K-coding; pin count 4+PE) and 63 V(DC) at 16 A (L-coding; pin count 4+FE – functional earth), respectively.
They both feature M12x1 threads, 8-mm to 13-mm cable outlets and screw clamp terminals. In order to meet the requirements of UL 2237, the threaded ring is electrically connected to the PE contact. UL 2237 certification is currently being prepared.
