variants so that the area of application of these connectors is easy to expand.
Conclusion
power to the devices using Power- over-Data-Line (PoDL). Current product development at binder does not just include PoDL. There is also a hybrid concept for the separate transmission of data and power. The new M8 connectors
for SPE come with the appropriate pin counts of 2 and 4.
M5 (Fig. 3) is available as a signal interface in applications where space is critical – from ultrasonic sensors to mini- valves and measuring instruments, all
the way to cobots. To provide maximum protection against electromagnetic interference for sensitive signals, M5 products from binder are available with 360° shielding. There are 3-pin and 4-pin versions as well as many customer-specific
From connection and interlocking technology to shielding and hybrid design – binder continues to drive further development of the M12, M8 and M5 packages. As a result, the classic connectors will maintain their role as a key technology in future automation concepts that will be characterized by gigabit data rates in demanding installation environments.

Ultra-compact hybrid FPC-to-board connector designed to offer space and power savings
The miniature hybrid BK22 Series from Hirose offers 15A power, 0.3A signal for portable and IoT devices H
irose has expanded its miniature hybrid flexible printed circuit (FPC) to board connector family to simplify mating and provide design
flexibility. CombinIng space savings and a high-power capacity, the BK22 Series connector enables OEMs to reduce the size of portable devices without sacrificing power performance.
The BK22 Series connector offers minimized contact resistance that facilitates power savings and allows up to 100W of power to be delivered via USB for fast charging. With two mounting points per contact, the BK22 connector design shortens the length of electricity flow to minimize heat generation when a high current is used. This board mounting design suppresses heat generation to 30°C or less, even when 15A is applied.
The FPC-to-board connector features

a fully armoured design that covers both ends of the housing with metal for enhanced robustness and a significant reduction in the risk of housing damage from misalignment when mating. Along with guidance ribs, a wide self-alignment range of ±0.47 mm in the pitch direction and ±0.405 mm in the width direction simplifies mating operation. Designed for pick and place mounting, the BK22 Series provides production time and cost savings. The BK22 Series is also said to provide impressive design flexibility. Using a FPC to connect the USB to the PCB, the USB can be placed anywhere within the design of the end-product.
The BK22 Series FPC-to-board connector features a multi-point dimpled contact design for both the power (6-point) and signal (2-point) contacts to ensure higher reliability and long operation life. A multi- point metal lock prevents unintended
unmating due to impact. An insert moulded header and receptacle eliminate gaps
between the terminals and housing preventing solder wicking. With a mated height
of 0.7 mm and a depth of 2.3 mm, the hybrid BK22 Series
connector is commonly used for portable devices like audio players, cameras, laptops and gaming consoles, as well as wearable devices like ear buds, smart watches and smart glasses.
“Designed for portable and wearable devices with built-in battery or USB connections, the hybrid BK22 Series offers enhanced features and capabilities that enable end-devices to be smaller, lighter,
and more reliable,” said Pete Lais, AVP of product management for Hirose Electric Americas.
Available in 4 or 6 signal positions with 2 power contacts, the BK22 Series has a rated voltage of 60V AC/DC and an operating temperature of -55 degree C to +85 degree C.
