Magnetic sensor assembly

A magnetic sensor, comprising:

• a magnet generating a magnetic field;
• a sensor housing including:
• a first side;
• a second side;
• a pocket including a first pocket portion and a second pocket portion, wherein the first pocket portion is formed in the first side, the first pocket portion being defined by an outer surface of the first side, and the second pocket portion of the pocket is formed in the second side, and the second pocket portion including an opening in the second side;
• and
• a magnet housing portion at least partially defined by the outer surface of the first side that defines the first pocket portion, the magnet housing portion including a magnet opening, and wherein the magnet is disposed in the magnet opening;
• a printed circuit board (“PCB”) assembly disposed in the pocket, the printed circuit board assembly including a first PCB portion and a second PCB portion, wherein the first portion of the printed circuit board assembly is a first printed circuit board and the second portion of the printed circuit board assembly is a second printed circuit board connected to the first printed circuit board, wherein the first printed circuit board is positioned in the first pocket portion, and wherein the second printed circuit board is positioned in the second pocket portion and oriented such that a longitudinal axis of the second printed circuit board is perpendicular to a longitudinal axis of the first printed circuit board;
• and
• a first sensor element and a second sensor element disposed on the second PCB portion and disposed in the second pocket portion, wherein the first sensor element and the second sensor element are configured to measure magnetic flux density of the magnetic field.

An assembly for a substrate station, comprising:

• a linear stator;
• a magnetic sensor positioned adjacent to the linear stator, wherein the magnetic sensor comprises:
• a sensor housing including a pocket and a magnet opening, the pocket comprising a first pocket portion and a second pocket portion;
• a permanent magnet disposed in the magnet opening;
• a printed circuit board assembly disposed in the pocket, the printed circuit board assembly including a first portion and a second portion, wherein the first portion of the printed circuit board assembly is a first printed circuit board and the second portion of the printed circuit board assembly is a second printed circuit board connected to the first printed circuit board, wherein the first printed circuit board is positioned in the first pocket portion, and wherein the second printed circuit board is positioned in the second pocket portion and oriented such that a longitudinal axis of the second printed circuit board is perpendicular to a longitudinal axis of the first printed circuit board;
• and
• a first sensor element and a second sensor element disposed on the second printed circuit board in the second pocket portion, wherein the first sensor element and second sensor element are configured to measure magnetic flux density, and the magnetic flux generated by the magnet is configured to pass through the first sensor element in a first direction and pass through the second sensor element in a second direction that is opposite to the first direction.
