Quick locking connector for power and signal interfacing
binder has introduced the Power Bayonet Connector PBC15. Its size corresponds to an M15 thread, bridging the gap between the widely used M12 and M23 designs.
The compact, yet robust connector is suitable for power supply particularly to three-phase motors or frequency converters. It features 3 power pins, for example to supply the 3 live phases of a 3-phase motor, 2 additional pins for signal transmission, as well as a Protective Earth (PE) contact.
The PBC15 design is specified within the DIN EN IEC 61076-2-116 standard. The quick-lock ensures simple, fast, and reliable locking by means of a quarter turn. Termination is provided by screw clamps. The PBC15 is initially available from binder as wireable female or male cable connectors, in each case as an unshielded or shieldable variant.
Process automation
Thanks to the rated values of 630 V and 16 A for the power interface, the circular connector is suitable for the power supply of small to medium-sized drives in process automation applications. With rated values of 63 V and 10 A, the signal pins can be used, for example, to control brakes or to query operating parameters such as temperatures. The shieldable variants of the Power Bayonet Connector are prepared for use in environments exposed to electromagnetic interference.
The compact design of the PBC15 offers very little space for an isolation appropriate to the voltage levels. On the other hand, the high currents require wire gauges of up to 2.5 mm2 and sufficiently large contacts in order to be able to ideally connect the wires. Nevertheless, the engineers at binder succeeded in designing the PBC15 in such a way that convenient assembly by means of the screw clamp terminals is possible.
