New sensor for harsh environments from BEI Sensors

LinkedIn +

The recently launched 9970 series hall effect rotary position sensor from BEI Sensors builds on a wide range of non-contacting sensors that are designed to provide long-life and high reliability in harsh and challenging environments.

Available in the UK from Variohm EuroSensor, the 6mm shaft-driven sensor features a choice of 0-5V ratiometric or 4-20mA output, with 2-bit resolution and electrical angle ranges from 30° (+/- 15°) up to 360° (+/- 180°) in 30° increments. Full endless rotation is included for maximum installation versatility. Accuracy is specified at +/- 0.6% of active electrical angle. Input voltage is 5V DC +/- 5% for ratiometric, or 9-30V DC for current output.

With two-hole mounting on 50mm centers and an integral amp superseal three-terminal connector, the compact sensor is a drop-in replacement for existing installations or a great choice for new steering angle and pedal position applications on construction and agricultural vehicles as well as position feedback for mining, marine and industrial equipment or for valve positioning in process control.

The sensor is housed in tough glass-filled PBT and includes IP67 and IP69K sealing. Non-contacting hall effect technology makes the 9970 particularly robust against shock and vibration. A life factor of more than 35 million cycles, high resilience to salts, oils and frequent washdown, and an operating temperature range of -40° to 125°C, in addition to protection for overvoltage, reverse polarity and short circuit, provide fit-and-forget reliability.
