Connectors for Medical Wearables from Rosenberger MultiMag 6 SeriesRosenberger’s compact and lightweight MultiMag 6 Series connectors are designed for small, space-constrained applications including fitness watches, smart glasses, and medical wearables and are especially ideal for applications that require frequent connection and disconnection. The series features magnetic, self-locating, and self-aligning interfaces that enable user-friendly, error-free, zero-force mating, as well as breakaway functionality, which enables the quick, easy, and deliberate removal of the plug and prevents acute tensile forces — intentional or otherwise — from accidentally causing user injury or product damage. Options include straight jacks compatible with panel or cable mounting, straight jacks for PCB mounting, and USB 2.0 Type-A cable assemblies with straight jacks and straight plugs with six gold-plated brass contacts and nickel-plated neodymium magnets. Connector solutions feature PBT GF30 housings and rigid contacts with solder-cup or through-hole terminations while cable assemblies feature PC-ABS housings and spring-loaded contacts. The RoHS-compliant series is designed for USB 2.0 specifications, including 5VDC and 0.5A operation, but is rated for a maximum of 24VDC and 1A in operating temperatures extending from -20°C to +65°C. At the recommended operating voltage and amperage, the series delivers a minimum of 5,000 mating cycles; at the maximum operating voltage and amperage, it delivers a minimum of 800 mating cycles.

Connectors for Medical Wearables from TE and HeilindHeilind Electronics stocks TE Connectivity’s micro-coaxial receptacles, which are used to connect RF cable assemblies or antennas to PCBs in application including consumer and medical wearables, ruggedized phones, smart meters, smart speakers, infotainment systems, and industrial devices. The series features a robust design manufactured with high-precision tolerances, offers excellent electrical performance, competitive low pricing, and fast delivery, and supports the drop-in replacement of existing RF receptacles to prevent customers from having to change their PCB layouts.

Connectors for Medical Wearables from Molex and Allied ElectronicsAllied Electronics & Automation stocks Molex USB 3.1 Type-C connectors, which have compact, space-saving designs with short bodies and short mating depths, support 5A and up to 10Gb/s, reduce battery charging time by 64% compared to 1.8A micro USB 2.0 connectors, and provide robust, reliable connectivity in an extensive range of high-speed data I/O applications, including consumer and medical wearable and IoT devices. The range employs high-temperature Nylon or Nylon 64 housing materials, a three-tier insert-molding process that increases connector strength and improves both mating durability and electrical reliability, and a mating tongue design that protects the interconnect from potential damage caused by mishandling, shipment, or assembly. It also features simple edge-contact beam geometry to facilitate high-speed data transmission, metal shielding on all sides for superior protection against EMI and RFI, beveled metal pins that provide a ground to the PCB and board retention strength, and grounding fingers.
