The first self-contained wireless photoelectric sensing solution for multiple monitoring and control applications has been introduced by Banner Engineering. The new wireless Q45 includes a sensor, radio and internal battery power supply in a single compact and robust housing. A variety of sensing modes are available in the series, allowing for functions including presence/absence, alignment, position, counting, monitoring and detection. Battery life is up to five years depending on sensor model and application and the housing is IP67 rated.
Signals from the sensors are received at a wireless network gateway that interfaces with all common PLCs and other industrial control systems. Basic gateways control two and six sensors, the system can be expanded for larger scale applications. Using a simple binding procedure, new sensors can be added to the network in minutes since there is no need to install any cabling.
The wireless sensors are designed for rapid, low-cost deployment and dependable operation in a wide range of situations. These include providing remote input for dry relay contacts, replacing failed cable runs, adding sensors to mobile applications, replacing complex cabling and connecting locations that were previously impractical or impossible. The secure, proprietary SureCross radio provides PLC level functionality and reliability over a range of 1 km. Data is transferred reliably by using frequency hopping and a proprietary protocol for security. The system does not affect other wireless devices in the 2,4 GHz ISM band. An alarm output is available in case the radio link is lost.
