Angle sensor

For mobile machinery and off-highway position measurement

The RFE-3200 series angle sensors are built for rotary position sensing tasks in the harsh environments encountered in agricultural machinery, off highway vehicles, and mobile machinery. It supports J1939 and CANopen.

The two-part ‘Touchless technology’ design comprises an encapsulated Hall sensor element in an IP69K-sealed housing and a separate magnetic position marker. The bearing- and shaft-less product offers a 12-bit or 14-bit angular resolution over its 0 ° to 360 ° measurement range in 10 ° steps.

The sensor comes with ISO 60068 rated shock and vibration ratings of 50 g and 20 g respectively and meets the standards for EMC noise emissions and immunity. A linearity of 0,5 % and repeatability of less than +/- 0,1 ° provide measurement precision in single channel and dual redundant versions, explained the company. A 12-VDC to 24-VDC input voltage as well as output options of 4 mA to 20 mA, 0,25 to 4,75 V, 0,5 V to 4,5 V are provided. CANopen and J1939 are supported.

Temperature range rates from -40 °C to +105 °C for the current and serial bus system versions. For higher ambient temperature resilience, the voltage and ratiometric versions have an increased temperature capability to + 125 °C, said the company. For DIN EN ISO 13849, PLd / Cat. 3 safety-related applications, dual-channel designs are also available. The housing measures approximately 41,5 mm x 59 mm x 18 mm including an integral Amp MQS 6-pin connector and two stainless steel M4 threaded insert fixings. A choice of position marker magnets include shaft-mounted, disc type, screw threaded, and flat designs.

Variohm Eurosensor (UK) represents and distributed Novotechnik’s (Germany) range of linear and rotary position sensing technologies.
