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. 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.

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.

3. 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°.

5. If needed for harsh applications, apply a suitable thread

locking compound to all screw threads.

2.2 Bare magnet actuator

1. 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.

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.

3. 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°.

5. If needed for harsh applications, apply a suitable thread

locking compound to all screw threads.
