Non-Contacting Position Sensor

BEI Duncan Electronics, a company of Custom Sensors & Technologies (CST), has added the 8360 non-contacting, through-hole position sensor series to its line. Featuring 360 degree continuous rotational capabilities in a low-profile, through-hole package, the company said the new sensor is applicable for uses where space and sensor mounting flexibility are needed.

Specifically, BEI Duncan said the 8360 is suited for applications in harsh environments such as industrial vehicles/material handling, agricultural and construction equipment, process controls, marine, aero-defense, energy, and valve actuation. Specific uses include position sensing for steering wheel, boom angle, throttling, pivoting, and traction control. The sensor measures 15.55 mm by 82mm by 113mm (HxWxL).

The 8360 sensor’s hollow shaft package is less than 16mm thick, for interface to space restricted applications as well as applications where a blind shaft mount is not feasible. With its thin through-hole package, the sensor can fit around or over the shaft.

BEI Duncan said the 8360 distinguishes 0.088 degree increments of motion with accuracy of better than ±2 mechanical degrees at room temperature over a full 360 degrees of continuous rotation, and 12 bit resolution. The 8360 also has redundant, dual analog outputs, IP65 sealing, operating performance across a temperature range of --22º to 185ºF, and capabilities to withstand vibration up to 10Gs, 10-1000Hz, total PSD: 4.94 Grms; and 50Gs shock, half sine pulse of 11msec duration.

Product modifications can include multiple turn capability and CAN Bus communication, as well as electrical angle, shaft interface, connector type, cable length, output slope, communication protocol, IP67 sealing, operating temperatures to 125º C, input voltage, and active rotational angles other than 360 degrees.
