This week’s Product Roundup highlights plastic optical fiber connectors from leading suppliers. Plastic optical fiber (POF) cables are made from light-conducting plastics, polymers, and acrylics, are typically used for short, low-speed data links and illumination, and are renowned for their ease of installation, low cost, and flexibility.

plastic optical fiber from HARTING available at AlliedAllied Electronics & Automation stocks HARTING’s Han-Modular Series connectors, which allow users to quickly, easily, and cost-effectively create optimized solutions for a wide variety of industrial applications by combining individual modules designed to transmit different media. The series is available with sliding, docking, or hinged frames and an extensive range of modules, hoods, housings, and accessories, and supports hybrid combinations of up to 12 off-the-shelf multimedia modules, enabling power, signal, data, and even compressed air transmission in space-saving, single-connector solutions with standardized footprints that enable easy integration into both new and existing equipment. Han-Modular Series connectors were also the first smart connectors capable of connecting to the Industrial Internet of Things (IIoT) at the component level and are easy to install, remove, and swap out, enabling extensive design flexibility and fast and easy retrofits within the same standard footprint. The series offers more than 40 module types, including placeholder modules for futureproofing in application areas with rapidly evolving performance standards, and can support 5–200A, 50–5,000V, pneumatic tubes spanning 1.6–6mm inner diameter, sensitive bus signals, and fiber optic signals over both plastic optical fiber (POF) and glass fiber cables.

plastic optical fiber frp, SOURIAU available at PEI-GenesisPEI-Genesis supplies SOURIAU’s UTO Series robust metal and shielded connectors, which support a wide variety of contacts — including machined crimp contacts, stamped and formed crimp contacts, coaxial contacts, PCB contacts, and size 16 fiber optic contacts designed to accommodate plastic optical fiber (POF) with a 0.039” core and 0.086” jacket — in mixed power and signal layouts that help reduce system complexity and minimize component and installation costs. UTO Series connectors are IP68/69K dynamic mated for waterproof performance in demanding indoor and outdoor applications, including those that require continuous underwater immersion, routine pressure washing, and dust protection, and are EMI shielded (65dB at 100MHz) to ensure high signal integrity performance in areas with high electromagnetic radiation. The series also ruggedly withstands climate ingress and exposure to salt spray (48 or 96 hours) and corrosive atmospheres while maintaining its mechanical and electrical functionality. In addition, it features a 1/3 bayonet coupling mechanism, which only requires a third of a turn to fully mate connectors and provides both audible and tactile confirmation of proper mating, effectively reducing installation time and eliminating connection uncertainty. The series’ size 16 fiber optic contacts for POF are spring loaded to avoid any air gap between the two optical faces, precision manufactured to ensure low insertion loss performance, and available as single jumpers, multiway harnesses, and active devices housings, depending on customer requirements. They support 650nm wavelength POF with maximum typical optical insertion loss of 2dB, exhibit 49N cable retention strength, and are rated for 50 mating cycles without cleaning, and a maximum of 500 mating cycles, in operating temperatures extending from -25°C to +70°C. Ideal applications for UTO Series connectors include energy generation, robotics, machine tools, building automation and control, instrumentation measurement, off-road vehicles, mining and railway equipment, and telecom data infrastructure.

plastic optical fiber from HARTINGHARTING’s PushPull Fiber connectors provide robust, quick-connect solutions for SCRJ plastic optical fiber (POF) and LC glass optical fiber (GOF) in single-mode and multimode applications. They have corrosion-resistant hoods and housings designed for high packing densities, IP65/67 environmental protection, two duplex optical contacts, and an internal locking mechanism that provides secure connections without any twisting or lever action. This internal locking mechanism enables both quick and easy mating an unmating in hard-to-reach and harsh environment locations, as well as higher-density layouts, and emits an audible click to confirm proper mating. These PushPull Fiber connectors also support 5.8–7.2mm outer-diameter GOF cable and 6.5–9.5mm outer-diameter POF cable and exhibit high mechanical stability.
