ELECTRONICS: With the introduction of a new selection of rugged, 1/3N Lithium Battery Holders for surface or through-hole mounting, Keystone Electronics Corp. continues to expand the availability of premium battery holders. These new battery holders are supplied with durable, heat-resistant, UL 94V-0- rated nylon housings ideal for all soldering and reflow operations. The SMT version (Catalog #498) features gold-plated phosphor bronze contacts. The THM version (Catalog #497) incorporates tin-plated phosphor bronze contacts and the heat-resistant nylon housings. The THM types mount directly on PCBs, securely positioned during wave soldering and placement. Both holders accept 1/3N 3-V Cell Lithium batteries from major manufacturers and are part of the company’s continuing growth selection of battery hardware specialties including contacts, holders, retainers and straps in a variety of materials for coin cell, button cell and cylindrical batteries. In addition to a broad line of quality interconnects, hardware and components, the firm maintains an application engineering group which is supported by expert stamping, machining and assembly operations.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
