WAL200
- Electrical Data: Nominal resistance options are 5 kOhm and 10 kOhm with a tolerance of ±20%. The independent linearity is ±1% of the measurement range, and the electrical angle is 280°. Maximum repeatability is 0.3°, and maximum hysteresis is 0.6°. The temperature coefficient of the voltage divider is 5 ppm/°C. Maximum recommended wiper current is 1 µA, with a maximum of 10 mA in case of malfunction. The power rating at 40°C is 0.3 W, and the minimum electrical life is 2 million movements.
- Mechanical Data: The mechanical range is 360° (continuous), with a minimum mechanical life of 2 million movements. Operating temperature ranges from -25°C to +75°C, and storage temperature ranges from -25°C to +100°C. The protection class is IP50.
- Insulating resistance is 10 GOhm at 500 VDC, 1 bar, for 2 seconds. Dielectric strength is 1 kV at VAC, 50Hz, for 1 minute at 1 bar. Vibration resistance is 10 g (Amax = 0.75mm, f = 30 to 2000 Hz), and shock resistance is 50 g (half sine pulse, 7 ms).
- Suitable for volumetric dosing systems and joysticks.
- Includes a hollow shaft, cost-effective design, and very good resolution better than 0.3°.
- Available with other nominal resistances, electrical angles between 30° and 340°, and customer-specific wires/connectors.
- Potentiometers should ideally be used as unloaded voltage dividers to avoid nonlinearities due to load and contact resistance.
- No accessories included.
