Eaton Accuprox Series

Inductive Proximity Sensor. Measures Objects As Far As 25 Millimeters From Sensor Face, Outputs Available in Current (4-20 or 0-20 mA), and Voltage (0-10V).

Eaton’s AccuProx sensors are a high-performance analog inductive sensor.  The AccuProx family of analog sensors provides unmatched measurement range, linearity, and accuracy in an affordable and compact tubular package.

Unlike standard inductive sensors, which send an output based on target presence or absence, AccuProx analog sensors provide an electrical signal that varies in proportion to the position of the metal target within their sensing range. This makes AccuProx ideal for applications requiring precision sensing and measurement.

AccuProx analog sensors can measure objects as far as 25 millimeters from the sensor face. This extended range can be achieved without making compromises often found in competitive products, such as reducing output accuracy or using nonlinear outputs, which must be corrected at the PLC.

    Analog sensors are frequently used in applications that require a higher level of precision than a standard digital sensor -
    - . For example, applications such as part inspection require a sensor that can detect very small measurement variances—sometimes fractions of a millimeter.
    - AccuProx has been specifically designed with these applications in mind.
    - -
    With repeatability of 20 micrometers and linear outputs, AccuProx can handle even the most precise applications. -
