Phoenix America’s R2 series absolute rotary position sensors suit heavy duty position feedback tasks

R2 series absolute angle sensors from Phoenix America provide accurate and environmentally robust 12-bit resolution position measurement with standard or user-specified output curves from 60° to 360° total range.

Available in a choice of analogue or PWM output versions, this sensor’s completely non-contacting Hall effect design - comprising a compact reinforced nylon sensor housing and a separate magnetic position marker - offers exceptional durability and a practically limitless working life with operational temperatures from -40 to +125° C.

Especially cost-competitive for larger volume OEM applications and well placed for demanding heavy engineering, agricultural and construction equipment installations, the R2 series is available with full support from Phoenix America’s UK- and European- based sister company, Variohm EuroSensor.

The R2 series sensor housing is simply mounted via two slotted holes on a 38 mm PCD – allowing rotary adjustment for precise magnet alignment. Typical installation would include a shaft-mounted target magnet axially aligned with an approximately 1.27 mm air gap.

Customer specific configuration can be accommodated on request. The sensor is powered from a 5 VDC supply voltage and interfacing flexibility is assured with a ratiometric output and a push-pull output stage that allows the use of pull-up or pull-down resistors. Standard or inverted output curves are available from +/-30° to +/-180° in 60° increments with angle-proportional output across 0.5 to 4.5 VDC and with the 0° mid-range point at 2.5 VDC. Custom and multi-slope output curves can be factory programmed to suit the customer’s application. Absolute output means no need for zero positioning or datum routines once the sensor is installed. The robust and durable build quality of the R2 is completed with a choice of cable lengths to 2 m and optional industry standard Deutsch or Metri-Pack connectors. Electrical protection includes reverse polarity, transient suppression and output short circuit.

R2 series absolute rotary position sensors are part of Phoenix America’s comprehensive range of magnetic-based sensing technologies that include magnetic encoders, speed and proximity sensors, sensor magnets, gear tooth sensors, hall commutators, magnet assemblies and more. Following its recent acquisition by the Variohm Group, Phoenix America’s unique range of sensor components are now fully available with complete technical support from Variohm EuroSensor.
