A sensor module configured to detect a vibration of a mechanical component includes a base connectable to the mechanical component, at least one spacer extending from the base, and a circuit board connected to the base by the spacer such that a mechanical vibration is transmitted from the component to the base to the spacer to the circuit board. The circuit board includes a circuit and wirelessly transmits signals indicative of a detected vibration. The spacer includes a body portion and a pin portion projecting from an end of the body portion. The pin portion extends into the at least one hole, and the body portion is blocked from passing though the at least one hole by contact with a region of a first side of the circuit board surrounding the at least one hole.

Spacer and sensor module for detecting a vibrational behavior of a mechanical component including the spacer

A sensor for sensing an angular position of a rotatable element with respect to a non-rotatable element, the sensor comprising an encoder fast in rotation with the rotatable element, and a sensor body fixed respective to the non-rotatable element. The sensor body includes at least one sensing element adapted to sense angular position or rotation speed and direction of the encoder, a signal processor support member, and a sensing data output connector comprising at least one electrical wire connected to the support member. The sensor comprises a tubular body (accommodating the connector), including a first half-shell integral with the sensor body and a second half-shell assembled with the first half-shell around the connector. A tubular body internal surface comprises at least one radial ridge adapted to block a translation of the output connector along a longitudinal axis of the tubular body by penetrating into a sheath of the connector.
