The latest Smart Heavy Duty Encoders developed by sensor specialist BAUMER are ideal for demanding heavier industrial applications, such as; Aggregates, Steel, Materials Handling, Ports, Cranes and Paper Mills. They represent the perfect choice for monitoring applications which include asynchronous motors. These uncompromisingly robust encoders are part of the incremental heavy duty HOG800 series which includes 3 options. The HOG840 a cost-effective option ideally suited to wind turbines and machinery, the HOG860 designed for more challenging applications featuring asynchronous drives and the HOG870, developed as a heavy duty encoder with redundant sensing and evaluation.
Among the key features of these robust encoders is enhanced protection against corrosion, shaft currents, overvoltage and mechanical stress. Additionally, Baumer has adopted the ‘smart’ functions of its broader industrial encoder products into these heavy duty options. For example, intelligent parameterisation of resolution, output level and rotation direction. New functions to monitor sensor status, temperature and operating time are also available.
An important feature of the HOG800 Series is their space-saving design with housings of merely 84mm in width, which, along with a sealed and user-friendly design, enables easier on-site installation, even in demanding conditions. Another important benefit is the encapsulated sensing unit which during terminal box installation is protected against ingress of dirt and dust with an IP40 rating. The terminal box features plug-in terminals to ensure easy and safe wiring while the wires inside are separated from the shaft to prevent cables becoming jammed or damaged.
Let’s take a closer look at the HOG800 variants
The HOG840 features high C4 corrosion protection to DIN EN ISO 12944 standards and is capable of operating in applications with temperatures ranging from -30 to 85ºC and cable lengths of up to 200 meters (HTL-P).
The HOG860 is designed for demanding applications on machines and asynchronous drives. It features extended electrical protection, specialised parameterisation options, status monitoring as well as an extended operating temperature range from -40 to 100ºC, along with CX corrosion protection.
The third option is the HOG870, a redundant heavy duty encoder with redundant sensing and evaluation, incorporating 6 additional outputs and designed for safety relevant applications. Additionally, for incremental signals the HOG890 features three digital switches for long distance transmissions of standstill, speed, direction and status information to control units.
