3. Tracking
Tracking on dual slide potentiometer is measured by follow ing formula with 2 V to 5 V applied voltage, at
1000±200 Hz between terminal 1 and 3.
Tracking error (dB)=20 log (V

Mechanical Specifications
1. Sliding Force
In a room at 5 °C to 35 °C, apply a sliding force to the lever at a point of 5.0 mm from the mounting surface at a
rate of 30.0 mm/1 to 2 seconds. The sliding force shall be 0.4 N to 3.5 N.
2. Lever Wobble
When a moment of 25 mN·m is applied perpendicularly on the top of the lever, the wobble of lever tip shall be
within 3 L/10 mm max. for one side. Where: L=Length of lever
F
3. Lever Angle
The angle of lever from the mounting surface shall be 90 °±2 ° max.
4. Detent Slip-out Force
In a room at 5 °C to 35 °C, detent slip-out force shall be 0.2 N to 1.5 N greater than the sliding force of lever.
5. Operating Life
15000 cycles min.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
