Analog Encoder with Push Buttons
Reliable, Contact Free Potentiometer Replacement
POSITAL has come up with a robust non-contact encoder to replace old-fashioned geared potentiometers (Analog Encoder with Push Buttons). Thanks to the contact-free recording of the angular position and revolution, the magnetic encoders from POSITAL are completely wear-free. Their magnetic functional principle not only enables a durable design and compact dimensions but also makes the encoders considerably less costly than optoelectronic models.
The encoders have a diameter of 36.5 mm and are available as solid and hollow shaft versions with industrial analog interfaces that provide current (4 – 20mA) and voltage (0 – 10V) output. The diagnostic yellow and green LED lights as well as the push buttons on the encoder make it very easy to install and scale.
Gear-and Battery-less Multi-Turn Technology
Because of the absolute multi-turn technology the magnetic encoders from POSITAL continue to record rotations even if no power is supplied and provide the values right after activation. They withstand shock and vibration conditions due to their gearless mechanics and they promise long lifetime through the battery free design since batteries are the most common cause of poor durability for such devices.
Scaling of Output using Push Buttons
The magnetic absolute encoders from POSITAL allow for electronic adjustment of the measuring range, enabling users to use the complete output range to record measurements. The units are configured by moving the encoders into the desired end positions, which are then stored in the encoder by means of a teach-in input using the Push Buttons. The measured values between these positions are scaled automatically.
Dead Band Functionality
The analog output features an upper and lower dead band range that if reached will detect if there is any wear and tear in the mechanical setup that the encoder is measuring. This avoids the controls from overreacting to invalid measurements.
