Input/ Output specifications: Hall PWM positioning feedback (3x and 4x in ordering example)
The Hall PWM positioning feedback is an option on LA23. This is especially suitable for wheelchairs or TECHLINE applications as the LINAK control
boxes are not capable of handling the signal.
The main advantages are:
• Hall potentiometer is close to being an absolute positioning system
• Hall potentiometer is a long lasting and wear-resistant positioning system
• PWM is more immune to noise than Hall Potentiometer feedback
• Enables compact products to have precise positioning (potentiometer increases the product potential).
