The Fischer UltiMate Series, Fischer Connectors’ flagship range for harsh environments, now includes a pre-cabled USB-C connector equipped with the company’s new ratchet locking system (RLS). The connector provides unmatched resistance to vibration and shock, ensuring safe connections for high-speed data transfer under the extreme operating conditions in mining.
The RLS’s fastening mechanism uses an asymmetrical tooth profile to securely lock under load and resist loosening under high vibration. Key benefits include exceptional vibration resistance (by maintaining lock under high-frequency vibration), tool-free operation (easy mating and unmating in the field, even with gloves), and durability with high rates of mating cycles.
“Our new USB-C RLS connector offers environmental and mechanical performance in compliance with IEC and MIL-STD norms,” said Alexandra Monchâtre, head of Product Management at Fischer Connectors. “This new product truly offers the best of both worlds: the ultra-standard and the ultra-rugged.”
In the Fischer UltiMate’s classical size 15 contact block (with up to 27 pins and 25.8-mm receptacle diameter), the RLS system achieves the best vibration and shock resistance in the entire Fischer Connectors product portfolio, withstanding 37.8 gRMS of random vibration and 300 g of shock amplitude.
The UltiMate USB-C RLS is available as a pre-cabled plug and receptacle (28-mm diameter) with a flex PCB. This all-in-one solution provides robust connectivity and flexibility in various design configurations for modern electronic devices, especially in applications where space, speed, and reliability are critical. It offers a compact design and supports USB 3.2 Gen 1×2 transmission with data rates up to 10 Gbit/s.
