Dubbed the Body-case, it is designed for wearable electronics applications including tracking and monitoring; emergency call and notification; bio-feedback sensors for healthcare, wellness and sports fitness. It can also be used for industrial electronics.

Each enclosure is supplied with two 18 mm spring bars for a wrist strap.

Power can be supplied by round or button cells on the PCB or by a rechargeable battery with a copper loop for charging the device inductively.

Body-Case is available in two sizes: new M (50 x 41 x 16 mm) or the existing L (55 x 46 x 17 mm). Both sizes can be specified either with or without a recessed top for a membrane keypad or product label.

The PCB is held securely between the top and bottom sections after assembly with four tamperproof Torx M2 x 6 mm screws.
