Product Description

RSS-2-300 OEM module uses the same radar technology as RSS-2-300 T radar sensor. RSS-2-300 OEM module is a small, compact, electronic module with integrated radar antenna, transciever and signal processor, that can easily be integrated in various third-party products. Our clients manufacture speed signs, speed cameras, traffic counters and railway warning signals that are all based on Geolux OEM radar module.

RSS-2-300 OEM module has been specifically designed to target all kinds of traffic applications. The module can be interfaced through serial RS-232 or RS-485 links, CAN interface or through programmable open-collector alarm outputs.

The OEM radar module is certified according to both European CE standards and American FCC standards, and reports vehicle speed with precision of ± 1 km/h.
