Panasonic Commercializes R35K Series Board to FPC Narrow Pitch Connectors for Wearable Devices

The new small connectors facilitate circuit design and contribute to device downsizing

Osaka, Japan – Panasonic Corporation announced today that its Industrial Solutions Company has commercialized the R35K Series of Board to FPC Narrow Pitch Connectors for use in wearable devices and will launch full-scale mass production in December 2020. The new connectors reduce the board mounting areas and are configured to be highly resistant to vibrations and impacts, contributing to reducing the size and weight and improving the reliability of such small electronics devices.

Wearable devices such as wristbands, earphones, and AR/VR glasses are widely used in various fields, including healthcare, entertainment and manufacturing, and are expected to further evolve and expand their market against the backdrop of increasing health awareness and labor shortages due to the declining birthrate and aging population. However, current mainstream connectors used in wearable devices have a problem that they require large board mounting areas due to complex wiring routes caused by their double-row terminal structure.

The newly developed connectors, with a single-row terminal structure, enable wiring from terminals of only one side, achieving an approx. 49% smaller board mounting area than Panasonic’s conventional products (S35 series), which helps reduce the size and weight of wearable devices. With Panasonic’s unique structure, the header and socket cannot easily be removed or break, which also improves device reliability. The connectors have also achieved large currents despite their small size, with the power terminal supporting up to 3 A and the signal terminal 0.3 A, meeting needs fast battery charging, thereby further promoting the widespread use of wearable devices.

Panasonic’s new R35K Series Board to FPC Narrow Pitch Connectors have the following features:

1. The single-row terminal structure reduces mounting areas and facilitates circuit design.
2. Panasonic’s unique structure, which is highly resistant to vibrations and impacts, improves device reliability.
3. Their support for large currents meets needs fast battery charging.

Suitable applications:

Wearable and hearable devices, including wristbands, earphones, and AR/VR glasses

Product Features:

1. The single-row terminal structure reduces mounting areas and facilitates circuit design.

With further downsizing and higher performance, electronic devices such as wearables and hearables require connectors that are smaller and facilitate circuit design. The issue with current mainstream connectors with a double-row terminal structure is their large board mounting areas due to complex wiring routes. By adopting Panasonic’s unique molding and process technologies, the newly developed connectors have achieved a single-row terminal structure, configured to have internal terminals aligned horizontally, enabling wiring from one side. Connector downsizing and simplified wiring routes have reduced mounting areas by approx. 49% compared to Panasonic’s conventional products (S35 series) and also facilitated circuit design.

2. Panasonic’s unique structure, which is highly resistant to vibrations and impacts, improves device reliability.

Devices worn on the body require high resistance to vibrations and impacts of a fall, etc. The connectors continue to adopt Panasonic’s unique Tough Contact structure, which enables the contact part to have adequate spring characteristics through high-precision bending using precision metal processing. The header and socket, which feature a high removal force and high robustness, will not easily be removed or break, improving device reliability.

3. Their support for large currents meets needs fast battery charging.

With a growing number of devices expected to be used for IoT, needs related to the reduction in charging time on the device side are expected to increase in the future. By adopting Panasonic’s unique material processing technology, the connectors have achieved large currents despite their small size, with the power terminal supporting up to 3 A and signal terminal 0.3 A, enabling fast battery charging, etc.
