The connector provides enhanced resistance to vibration and shock, ensuring safe connections for high-speed data transfer under extreme operating conditions in sectors such as defence, mining, construction, motorsports and railways.
The Fischer UltiMate USB-C connector with the Ratchet Locking System (RLS) combines high-speed data transmission with robust mechanical performance.
Leveraging its core competencies in ruggedisation, sealing, miniaturisation, and data transmission, the connector has been designed to provide optimal reliability in mission-critical environments, ensuring safe and stable connections.
The Ratchet Locking System (RLS) 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 un-mating in the field, even with gloves), and durability with high rates of mating cycles.
In the Fischer UltiMate’s classical size 15 contact block (with up to 27 pins and 25.8-mm receptacle diameter), the RLS system can withstand 37.8 Grms of random vibration and 300 g of shock amplitude.
The UltiMate USB-C connector with RLS has been independently validated to withstand 5.35 Grms of random vibration (50–2000 Hz, 3x1.5 hrs, no discontinuity >1 μs), 10 g of sinus vibration (10–500 Hz, 3x3 hrs, no discontinuity >1 μs), and shock up to 100 g (half sine pulse, 6 ms, no discontinuity >1 μs).
Additional features include an IP68 sealing for the plug; hermeticity for the receptacle; an operating temperature range of -30 °C to +80°C; corrosion resistance of 350 hours of salt mist; 3,000 mating cycles; and 360° EMC shielding.
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 1x2 transmission with data rates up to 10 Gbit/s.
The new USB-C RLS connector expands Fischer Connectors’ offerings across its high-speed Core, MiniMax, and UltiMate series, which support data protocols such as USB 3.2, Ethernet up to 10 Gbit/s, Audio/UHD Video up to 18 Gbit/s (HDMI 2.0 type), and Single Pair Ethernet (SPE).
