The 330878-50-00 is a 3300 XL 50 mm Proximitor Sensor designed as a fundamental signal processing component of eddy current proximity transducer systems. This device accepts a noncontacting input from one 3300 XL 50 mm proximity probe and extension cable, converting the relative distance between the probe tip and target into a proportional voltage output. Engineered specifically for long-range displacement monitoring, the sensor is optimized for key industrial machinery measurements where standard proximity probes lack the required measurement range. It provides seamless system interchangeability, delivering an output scaling identical to older legacy systems to facilitate straightforward retrofitting and modernizing without altering monitor configurations.
