Power bayonet connector has quick locking mechanism
The power bayonet connector PBC15 from binder can be used for power supply and signal linking of devices using just one cable. The compact connector also has quick locking and is tailored for fast wiring and installation.
The size of the new industrial connector corresponds to an M15 thread and in power supply connectors bridges the gap between M12 and M23 designs. The compact, yet robust connector is suitable for power supply particularly to three-phase motors or frequency converters. It features three power pins to supply the three live phases of a three-phase motor, two 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.
The circular connector is suitable for the power supply of small to medium-sized drives, with rated values of 630V and 16A and 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 EMI. Typical applications are in the fields of intralogistics, factory and process automation, as well as machine engineering.
The PBC15 has a PE pin, which is designed as the centre contact, to the connector housing. The connection is established by means of a spring plate which is pressed together with the PE contact inside the contact body, to form a secure connection to the housing.
Until now, electrical connectivity for small and medium-sized three-phase drives has often been characterised 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, including binder, has developed a standardisation 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. The power bayonet connector from binder complies with this design standard, which allows customers to achieve a substantial level of independence from individual suppliers when developing their applications.
