PosiHall - Magnetic Multiturn Encoders

True-absolute. Highly rugged.

posihall^® magnetic multiturn encoders are the robust alternative to optical encoders that often fall short in harsh conditions. posihall^® sensors measure angular positions over multiple revolutions with the help of a 'true-absolute' magnetic measurement principle. They are capable of maintaining failure-free, accurate funtionality in the event of high vibrations, powerful impacts, and temperatures between -40° C (-40° F) and +85° C (+185° F). Their robust housing complete with specially encapsulated electronics makes them resistant to extreme environmental conditions and therefore the ideal solution for heavy-duty applications.
posihall^® sensors are also available with redundant outputs for safety-related applications.

 Advantages at a glance

• True-absolute measurement principle
• Measurement range up to 31 x 360°(PH36) and 255 x 360° (PH58 and PH68)
• Shock, vibration and dirt resistance
• Integral shielding against magnetic fields
• Single-turn linearity of 0.3%
• Degree of protection up to IP69

posihall^® sensors offer contactless, wear-free measurement of rotation angles using multiple mechanically coupled multihall sensors. These work together to capture up to 255 revolutions for a true-absolute measurement. This means that a correct measurement can always be displayed regardless of external interference - for example, after a power failure.
