Now available from Variohm EuroSensor, Novotechnik’s recently launched RFX-6900 series touchless technology angle sensor is well suited for precision rotary position feedback for mechanically extreme applications in automotive, agricultural and construction equipment. Offering excellent durability, the ECE E1-approved Hall Effect device features a two-part mechanically decoupled design with the sensor electronics housed in a fully sealed aluminium housing and a separate magnetic position marker available in a range of styles.
The RFX6900 series has continuous rotation with six standard measuring ranges in 60 degree increments up to its 0 to 360 degree full range. Single and part- or full-redundant dual-channel versions are available with current output of 4…20mA at 12-bit resolution. A wide choice of output characteristic options include rising cw & ccw, staggered, trapeze and parabolic as well as custom gradients. Independent linearity is 0.5 per cent F.S. and supply voltage is 12…24V DC with an optional 9…34V DC which suits battery operation.
This sensor is suitable for use in safety-related applications according to ISO 13849 up to PLd and has E1 approval from the German Federal Motor Transport Authority. Installation for the sensor housing (69mm diameter × 20mm wide) is made easy with screw mounting from either face and an optional mounting plate provides further mounting orientation possibilities. Electrical connection flexibility is also offered with a choice of cable and M12 connectorised versions. The anodised aluminium housing includes salt-spray corrosion protection with protection class options of IP67 for connector versions and IP6K9K for cable connection. Magnetic marker alternatives include shaft mounted and threaded screw versions, and with a radial offset tolerance of up to +/- 3mm between marker and sensor electronics straightforward installation is made easy.
The sensor´s mechanical specification includes excellent vibration and shock ratings that combine with an operational temperature range of -40…+85degC to ensure exceptional durability for applications on heavy-duty mobile machinery. The two-part design – with no contact between sensor and magnet – means completely wear-free use with a virtually limitless operational life.
