10/100-Mbps Ethernet Industrial Switch – Unmanaged, for Extreme Temperatures

This compact 10/100-Mbps Ethernet industrial switch is designed for rugged industrial environments with a broad temperature range. Available with 5 or 8 RJ-45 ports featuring auto MDI/MDI-X, the switch provides stable network connections in demanding settings. Its robust IP30-rated metal housing protects against dust and debris, and the temperature tolerance from -40 to +75 °C enables reliable performance under extreme conditions. With redundant 12 to 48 VDC power input and fail-safe mechanisms such as reverse polarity protection and a P-fail relay, operational readiness is always ensured.

The switch is ideal for applications in surveillance and security, building automation, remote control in oil and gas facilities, military communication networks, and factory automation. Integrated broadcast storm protection enhances network stability. It supports both DIN rail and wall mounting, and a panel mounting kit is included. Covered by a 1-year Double Diamond™ warranty, this switch promises reliability and quality.
