Installation Instructions for the RTP Series Hall-effect Rotary Position Sensors 1.0 GENERAL INFORMATION The RTP Series Hall-effect Rotary Position Sensors provide non-contact sensing in harsh transportation and industrial applications at a competitive cost. These products use a magnetically biased, Hall-effect integrated circuit (IC) to sense rotary movement of the actuator over a set operating range. Rotation of the actuator changes the magnet's position relative to the IC. The resulting flux density change is converted to a linear output. 2.0 MOUNTING INFORMATION (see Figures 1 and 2) 2.1 Housed magnet actuator 1. 2. 3. 5. Locate the sensor and the magnet in the desired position. Ensure the air gap between the sensor and the magnet will not exceed that noted in Table 2. Clamp the sensor on the customer-provided mounting plate and place the magnet on the customer-provided mounting shaft. Ensure the orientation arrow on the magnet points toward the connector end of the sensor. Apply the supply voltage to the sensor and monitor the output voltage. When the output voltage is at the midpoint as shown in Table 4, tighten the set screws on the magnet. The sensor angle is 0. If needed for harsh applications, apply a suitable thread locking compound to all screw threads. 2.2 Bare magnet actuator 1. 2. 3. 5. Locate the sensor and the magnet in the desired position. Ensure the air gap between sensor and magnet will not exceed that noted in Table 2. Clamp the sensor on the customer-provided mounting plate and place the magnet on the desired actuator. Ensure the orientation hole on the magnet points towards the connector end of the sensor. Apply the supply voltage to the sensor and monitor the output voltage. When the output voltage is at the midpoint as shown in Table 4, mount the magnet. The sensor angle is 0. If needed for harsh applications, apply a suitable thread locking compound to all screw threads. Issue A Table 1.
