Description
The Kramer SWT3-41-U-T is a high-performance 4x1 USB switcher transmitter designed for modern collaborative spaces, online meeting rooms, and flexible BYOD environments. Equipped with two USB-C and two USB-B host ports, it enables seamless auto-switching between active USB hosts while extending both USB and Ethernet signals over long-reach CAT infrastructures.
This advanced transmitter supports local and remote USB peripherals—including PTZ cameras, microphones, touch displays, storage devices, and other USB 3.2/2.0 devices—ensuring smooth transitions between meeting participants and host devices. With built-in intelligent control, PoE support, 2-way power over CAT links, and secure 802.1x network authentication, the SWT3-41-U-T simplifies deployment while maintaining enterprise-grade reliability.
Designed for BYOD convenience, it provides up to 60W USB-C PD charging, high-speed USB 3.2 data throughput up to 10Gbps, and flexible mounting options such as under-table installation or half-rack integration. Ideal for hybrid meeting environments, multi-device switching, and long-distance USB extension.
