Sensor for a Fingerboard Latch Assembly

A sensor system for a fingerboard latch assembly that comprises a latch, the sensor system comprising a sensor assembly and a processor, wherein

• the sensor assembly comprises:
• at least one sensor arranged to sense the position of the latch;
• a sensor circuit connected to the at least one sensor and arranged to derive a signal representing the position of the latch;
• and
• a communication circuit arranged to communicate the signal representing the position of the latch, and
• the processor is arranged to determine at least one parameter of the motion of the latch from the signal representing the position of the latch, the at least one parameter including at least one of speed of the latch, acceleration of the latch, overshoot of the latch or vibration of the latch, the external processor further being arranged to analyze the determined parameter of the motion of the latch and on the basis thereof to make a prediction of failure of the latch.
