Kaman Precision Products/ Measuring, Middletown, CT, has introduced the KD-2446, a high-precision proximity sensor system that offers RoHS and CE compliance in a compact DIN package. With a 10-KHz analog output and threshold-adjustable 3.3-KHz switched output, the sensor is designed for high-speed automated manufacturing and process control applications. The sensor provides 0.008%FS resolution and 0.56%FS switch point hysteresis. Applications include displacement, vibration, sorting, and event capture. The sensor uses inductive eddy current technology that measures without touching the target, and works with both ferrous and non-ferrous targets. The system consists of two sub-assemblies: the sensor with integral cable, and the signal conditioning or electronics module. Input voltage is variable from 12 to 24 V DC, and gain is adjustable for up to 22 V output (with 24 Vdc input). The system comes standard with one of two production sensor configurations: the 9C or the 5CM. Both rugged sensors are rated for continuous operation up to 400 °F.
