SV03 Series Specifications and Test Methods

9

Rotational Life

The adjustment rotor should be continuously rotated within ±160° of effective electrical rotational angle, at the rate of 3 cycle for 1

second for 300 thousands cycles under the condition of 25±2°C of temperature without loading.

Then, the rotary position sensor should be kept in the dry box for 10±5 minutes.

8

Low Temp.

Exposure

The rotary position sensor should be stored in a chamber at a temperature of -40±3°C without loading for 1000±8 hours.

After removing from the chamber, the rotary position sensor should be kept in the dry box for 1 to 2 hours.

7

High Temp.

Exposure

The rotary position sensor should be stored in a chamber at a temperature of 125±2°C without loading for 1000±8 hours.

After removing from the chamber, the rotary position sensor should be kept in the dry box for 1 to 2 hours.

6

Humidity Load Life

Full rated continuous working voltage not exceeding 5Vdc should be applied intermittently between terminal #1 and terminal #3 of the

rotary position sensor, 1.5 hours on and 0.5 hours off, for 1000±8 hours in total in a chamber at a temperature of 85±3°C and relative

humidity of 85±5%. After removing from the chamber, the rotary position sensor should be kept in the dry box for 5±1/6 hours.

5

Shock

(1,500G) max. can be applied in each 3 times (total 18 times) in the 3 direction of x, y, and z with bidirectional.

Then, the rotary position sensor should be kept in the dry box for 1 to 2 hours.

4

Vibration

The rotary position sensor should be log-sweeped by the sine oscillatory wave of the maximum amplitude 1.5mm, Acceleration

minutes in the 3 direction of x, y, and z., 12 cycles should be applied during 12 hours in total.

Then, the rotary position sensor should be kept in the dry box for 1 to 2 hours.

3

Humidity

The rotary position sensor should be stored in a chamber at temperature of +85±3°C and relative humidity of 85±5% for 1000±8

hrs. After removing from the chamber, the rotary position sensor should be kept in the dry box for 24 +8/-0 hours.

2

Temperature Cycle

(Thermal Shock)

The rotary position sensor should be subjected to Table 2 temperature for 5 cycles.

Then, the rotary position sensor should be kept in the dry box for 24 +8/-0 hrs.

1

Linearity

Linearity should be specified a deviation with the below ideal straight line, between ±160° from the index point which is 50% of out

put voltage.

The ideal straight line has 100%/333.3° as taper and pass the above index point.

Measurement is performed using the following measurement circuit, and the rotor should be rotated to clockwise direction.

No.

Test Methods

Item

The tests and measurements should be conducted under the condition of 15 to 35°C of temperature 25 to 75% of relative humidity and 86 to 106 kpa of

atmospheric pressure unless otherwise specified. If questionable results occur that have been measured in accordance with the above mentioned conditions,

the tests and measurements should be conducted under the condition of 25±2°C of temperature, 45 to 55% of relative humidity and 86 to 106 kpa of

atmospheric pressure. When the potentiometer is tested after soldering on PCB, it should be tested after being kept in a room (15 to 35°C, 25 to 75%RH)

over 24 hours except "Resistance to soldering heat".
