HALL-EFFECT ROTARY POSITION SENSORS RTY SERIES

General Information

The RTY Series utilizes a magnetically biased, Hall-effect integrated circuit (IC) to detect rotary movement of an actuator shaft within a specified operating range. As the actuator shaft rotates, the magnet's position relative to the IC changes, resulting in a flux density variation that is converted into a linear output signal.

Mounting Information

Mount the sensor and/or lever using flat washers and screws as depicted in Figures 1 and 2. For applications in harsh environments, it is recommended to treat the screw threads with a suitable thread locking compound.

Table 1. Specifications

¹ Applies to RTY sensor without lever only.

² Removes the requirement for the customer to have to invert the logic associated with the application. This is a convenience for the customer, and in some cases, can simplify the customer's overall solution.

This diagram illustrates the output voltage characteristics relative to actuator position for both Standard and Inverted output configurations. Points A, B, and C represent specific output levels, with B denoting the zero reference.

Standard Output:

• A: Left output: 0.5 Vdc
• B: Zero reference
• C: Right output: 4.5 Vdc

Inverted Output:

• A: Left output: 4.5 Vdc
• B: Zero reference
• C: Right output: 0.5 Vdc

The diagram also indicates angular divisions (θ/2) relative to the center.

Table 4. Functional Characteristics

This section details the functional characteristics, including linearity and accuracy, across various sensing angles for both standard and inverted output configurations. The graphs illustrate the relationship between Actuator Position (degrees) and Output Voltage (Vdc).

Standard Input Graphs:

• For sensing angles such as 50° (±25°), 60° (±35°), 70° (±35°), 90° (±45°), 120° (±60°), 180° (±90°), and 270° (±135°), the output voltage typically increases linearly from approximately 0.5 Vdc at the minimum actuator position to 4.5 Vdc at the maximum actuator position. Point B signifies the zero reference.
• The graph for 360° (±180°) shows this linear relationship across the full rotational range.

Inverted Input Graphs:

• For the same sensing angles, the output voltage typically decreases linearly from approximately 4.5 Vdc at the minimum actuator position to 0.5 Vdc at the maximum actuator position. Point B signifies the zero reference.
• The graph for 360° (±180°) shows this inverted linear relationship across the full rotational range.

Notes on Specifications:

• Linearity Error: This is defined as the deviation of the measured value from the best fit line.
• Accuracy: Measured as a deviation from the index line, which has an ideal slope. Accuracy is valid at 25 °C ±5 °C and when the sensor output is correct at the 0° position for its ideal application value.
