WAL305
WAL305
- Electrical Data: Nominal resistance options are 1, 5, or 10 kOhm with a tolerance of ±20%. The independent linearity is ±1% of the measurement range. The electrical angle is 340°, with a maximum repeatability of 0.3° and a maximum hysteresis of 0.6°. The temperature coefficient of the voltage divider is 5 ppm/K. Recommended wiper current is a maximum of 1 µA, with a maximum of 10 mA in case of malfunction. The maximum power rating at 40°C is 0.3 W, and the minimum electrical life is 4 million movements.
- Mechanical Data: The mechanical range is continuous at 360°, with a minimum mechanical life of 4 million movements. Operating temperature ranges from -25°C to +75°C, and storage temperature ranges from -40°C to +105°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 at Amax = 0.75mm, f = 30 to 2000 Hz. Shock resistance is 50 g with a half sine pulse of 7 ms.
- Suitable for convertible roofs and automatic tailgates of cars.
- Includes a hollow shaft, cost-effective design, 4 million movements, and very good resolution better than 0.3°.
- Available options include other nominal resistances, linearity of ±0.5%, electrical angles between 30° and 355°, and customer-specific cables or wires.
- Potentiometers should ideally be used as unloaded voltage dividers to avoid nonlinearities due to load and contact resistance.
- No accessories included.
