Posital: Upgraded rotary encoders

Posital’s updated analog programmable rotary encoders are designed for positioning tasks that use analog control systems. Outputs are either voltage (0-5 V, 0.5-4,5 V, 0-10 V or 0.5-9.5 V) or current (4-20mA).

Features include:

• Broader supply voltage range for mobile machine applications

• Increased accuracy, resolution and number of turns

• Further programmability function with our UBIFAST configuration tool

• Singleturn encoders with measuring range less than 360 degrees available

• Fractional singleturn measuring range as factory default Y thereby creating a higher resolution measurement if the range is less than 1 turn

Customizable programmable measurement characteristics

An important feature of the Posital analog encoders is that they are programmable with measurement characteristics that can be customized to meet specific application requirements, (This feature is also available with POSITAL’s digital encoders with SSI and incremental interfaces.) Programming can be carried out at the factory, in a distributor’s warehouse or at the customer’s job site, thanks to Posital’s easy-to-use UBIFAST programming tool. Programmable characteristics include direction of rotation (CW or CCW), zero set and the encoder output range. Measurement range programming allows the full range of electrical outputs (voltage or current) to be set to match a user-defined range of mechanical motion, resulting in significant improvements to control system accuracy. For single-turn models, the measurement range can be set to 90°, 180°, 270° or 360°. For multi-turn models, the range can be set anywhere between 1 and 65,536 complete rotations. Analog encoders are available with push-buttons on the housing that enable the user to easily specify the upper and lower limits of the mechanical motion, with the electrical output fully spanning this range.
