Miniature CANopen Encoder With Redundant Hall Sensor

Despite its small diameter of 22.2 mm and a housing length of less than 39 mm, the 80 g light encoder integrates a redundant Hall sensor for angle detection from 0 ° to 360 ° and a CAN bus interface. Due to the double measurement value acquisition, the encoder is also suitable for safety-relevant applications.

High repeat accuracy

The sensor works with a resolution of 12 bit / 360 ° and achieves a linearity of ± 0.2% with a repeat accuracy of 0.1 °. The signals are output using the CANopen protocol. The encoder, which is provided with an 8-pin ribbon cable as the connecting cable, is attached using the M10x0.75 central attachment. Thanks to the contactless magnetic measuring principle of the Hall sensor system, the encoder achieves a mechanical service life of at least 300 million cycles.

The miniature encoder with protection class IP65, a housing made of seawater-proof aluminum and a 6 mm thick shaft made of stainless steel 1.4305 is also extremely robust and can be used in the temperature range from -40 ° C to 80 ° C. The shock and vibration resistance of 25 g over 6 ms or 4 g at sine frequencies from 5 Hz to 100 Hz ensures high insensitivity to external mechanical influences. The encoder can be supplied with a supply voltage of 18 V to 36 V DC, the current consumption is approx. 50 mA. (jv)
