Bourns Introduces Advanced Hybrid Position Sensor Designed for Certain Harsh Environment RS-485-based Applications


May 3, 2021

Bourns, Inc. has recently introduced an innovative hybrid position sensor for RS-485-based applications in certain harsh environments. Designed to meet the specifications of heavy-duty applications requiring long cycle life and high reliability, the new Bourns Model HES38U-RS485 hybrid position sensor offers a rotational life of up to 5 million shaft revolutions with 10 turns of absolute position. It has an Independent Linearity specification of ±0.1 % max, an IP65 seal rating and an operating temperature range of -40 °C to +85 °C.

The advanced hybrid design enables the Model HES38U-RS485 to deliver enhanced linearity, resolution and accuracy. Highly repeatable and resistant to vibration/shock and fluid/dust ingress, this robust position sensor is an optimal solution for a variety of industrial feedback applications including patient platform positioning, 3D imaging position, pneumatic control valve position and actuator motor position as well as for automated manufacturing robotics.

It features a 6 mm diameter slotted shaft supported by a mechanical angle of 3600 ° ±10 ° and is available with customized longer cable lengths and in a servo mount configuration. The Bourns Model HES38U-RS485 is available now and is RoHS compliant.
