Among a wide range of products that Belgium-headquartered Banner Engineering will present at Intertraffic, two products stand out – the R-GAGE QT50R radar sensor and the DX80 Wireless I/O Node and Gateway.

The R-GAGE QT50R is a FMCW (frequency modulated continuous wave) radar sensor that can detect both moving and stationary objects, regardless of shape or colour. With its compact and robust, dirt-resilient IP67 housing and weather immunity algorithms, the company says the device is able to withstand harsh environments. The QT50R is available as a retro version, with background teach, or as a diffuse detection with adjustable cut-off point, each with a maximum range of 15 metres.

The DX80 Wireless I/O Node and Gateway answers a particular need in traffic management systems. Dynamic information panels for drivers can indicate dangerous situations they need to be aware of, but , as Banner Engineering points out, typically such panels are activated by sensors that are several hundred, if not a thousand or more metres away, so cabled solutions are not viable.

The company’s DX80 Wireless I/O systems can transmit a variety of signals (digital, analogue and RS485) with a response time less than 100 ms up to three kilometres distance (line of sight). The radio transmission is license-free, yet it is reliable and secure because of frequency hopping and the use of a proprietary protocol. Units can be powered with industry standard 10 to 30 Vdc, solar panels, ideal for repeater units, or lithium battery with up to five years of estimated lifetime.
