Quick lock M15 rugged power connector
The latest Power Bayonet Connector from binder is suitable for power supply and signal linking of devices via just one cable.
The PBC15 rugged power connector from binder in Germany uses an M15 thread to bridge the gap between the widely used M12 and M23 designs.
The robust connector is particularly suitable for three phase motor power supplies 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.

Electrical connectivity for small and medium-sized 3-phase drives has often been characterized by products from different manufacturers that have featured different designs for connecting the same motor. Those products are not interchangeable.
A committee of various companies, also including binder, developed a standardization proposal to create a uniform interface for this application field. This proposal was published in April 2022 as the official draft standard DIN EN IEC 61076-2-116 and the Power Bayonet Connector complies with this design standard. This allows designers to achieve a substantial level of independence from individual suppliers when developing applications.
The rated values of 630 V and 16 A for the power interface supports power to small to medium-sized drives. 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. Typical applications are in the fields of intralogistics, factory and process automation, as well as machine engineering.
The design of the connect supports wire gauges of up to 2.5 mm2 and sufficiently large contacts in order to be able to connect the wires for high current design but still enable convenient assembly with screw clamp terminals.
Another challenge arose with the coupling of the PE pin, which is designed here as the centre contact, to the connector housing. The connection was established by means of a spring plate which was pressed together with the PE contact inside the contact body, thus forming a secure connection to the housing.
“With the PBC15, we have succeeded in creating a power-dense and easy-to-use connector that is ideally suited for small and medium-sized 3-phase motors. With the high ampacity of its 3 power contacts and with its 2 signal pins, the connector is extremely versatile in supplying power to automation components and drives. The quick locking as well as the screw clamp termination allow users to easily and quickly wire and install the connector,” said Philipp Zuber, product manager with binder.
