Rugged I/O connector offers 3Gbps transmission speeds for next-generation industrial modules

Hirose has developed a rugged I/O connector with an innovative space-saving design that enables a size reduction of industrial modules. The IX Series connector provides a space savings of up to 65% compared to RJ45 solutions, and up to 28% compared to competing snap-in I/O connector offerings. The connector combines high reliability and enhanced EMI/ESD shielding with high-speed transmission capability of 3Gbps all in a compact package. Supporting CAT5 cabling, the connector offers significant space-savings potential in equipment such as factory automation controllers, programmable logic controllers, servo amps, servers, robotics and more. Available in a right angle or straight version, it has maximum dimensions of 22.9mm x 8.4mm x 14.3mm. The connector receptacles can be mounted in parallel with a pitch distance of only 10mm. The narrow width of the receptacle is particularly beneficial when multiple connectors are positioned on a single PCB side-by-side. Featuring a rugged and reliable design, the snap-in I/O connector has a positive metal lock with a preload spring mechanism that provides a clear tactile click and ensures complete, secure mating. The preloaded springs are designed to prevent unintended cable removal, and to extend the operating life to more than 5000 mating/unmating cycles. "The compact IX Series connector offers a significant size reduction compared to competing I/O connectors. The small receptacle footprint enables the size reduction of a unit comprised of multiple daisy-chained I/O modules," said Rick van Weezel, vice-president of sales and marketing for Hirose Electric USA. The receptacle shell is mounted on the PCB via a through-hole solder legs to enhance PCB retention and to resist the wrenching of the cable assembly, protecting the SMT leads. The wire-termination unit and cable clamp are integrated into a single plug shell, which prevents the connecting part of the cable assembly from being affected by the load on the cable. Because the connector's receptacle supports THR soldering as a substitute for manual soldering, it can be mounted on the PCB containing both THT and SMT components in a single SMT process. This also contributes to the high PCB retention force. The connector has a rated current of 0.5A (all pins), 1A (any two pins), 2A (pin No. 1 and No. 8 only). With an operating temperature range of -40C to +80C, the connector has a rated voltage of 30VAC.
