摘要:
An example angular position sensor assembly includes a sector member that rotates within a ring including a permanent magnet disposed centrally within the ring and a Hall-effect sensor adjacent the permanent magnet on an opposite side of the permanent magnet from the sector member.
摘要:
The present invention includes a rotary sensing system that includes a shaft, a magnet encircling the shaft, a pair of plates, each of which is positioned near distal ends of the magnet, and at least one sensing device. The magnet generates a magnetic field, the angle of which changes as the shaft rotates. The pair of plates directs the magnetic field generated by the magnet towards the at least one sensing device. The at least one sensing device is sensitive to the changes in the angle of the magnetic field, which are indicative of an angular position of the shaft.

A non-contacting sensor assembly including a connector assembly and a magnet assembly. The connector assembly includes a sensor coupled directly to the end of the terminals of the connector assembly. A sleeve is overmolded around and seals the sensor and the terminals. A capacitor is soldered in a recess in the terminals. The terminals include flexible regions, such as regions of reduced thickness, which reduce the effects of thermal expansion/contraction stresses on the solder. In one embodiment, the sensor assembly is a rotary position sensor assembly in which the magnet assembly is molded into a rotatable drive arm assembly located in a housing, the connector assembly is coupled to the housing, and the sensor extends into the housing and into adjacent relationship with the magnet assembly.
摘要:
An overmolded electronic device includes a pre-mold assembly having a positioning pin that extends upward through a mold material into contact with an inner cavity of a mold. The positioning pin is disposed within a containment area that is defined by sets of ribs configured in and conformed on the pre-mold assembly. The positioning pin thereby is sealed within the containment area that is in turn sealed from the remainder of the electronic device that prevents the intrusion of moisture or other contaminants into undesirable locations of the electronic device.
摘要:
An apparatus including an inner member mounted for rotation about an axis, an outer member mounted for concentric rotation about the inner member relative to the axis, the outer member having an inner surface adjacent the inner member and an outer surface, and a sensor mounted adjacent the outer surface of the outer member so as to measure the rotational speed of the inner member.
摘要:
An actuator and sensor assembly comprising respective sensor and actuator housings defining an interior chamber. Clips on the sensor housing engage the actuator housing for coupling the sensor and actuator housings together. The sensor housing includes a wall defining a pocket. A connector with a sensor couples to the sensor housing in a relationship wherein the sensor extends into the sensor housing pocket. A movable piston is located in the interior chamber and a tube thereon defines a receptacle for a magnet located adjacent the pocket. The piston is seated on a flexible diaphragm. An actuator shaft includes one end coupled to the piston and an opposite end coupled to a movable object. A plurality of pins in the actuator housing mount the assembly to a support bracket. The sensor senses changes in the magnetic field in response to changes in the position of the magnet relative to the sensor.
