ROTARY INCREMENTAL ENCODERS

Eltra

Rotary incremental encoder series for solid, blind/through hollow shaft

Rotary encoders are electro-mechanical devices designed to control the position and the angular speed of mechanical axles in motion.
Rotary incremental encoders are so defined since they track the increase (variation) in respect to a position taken as a reference point and independently from the direction of the rotation. The incremental encoder senses rotation, speed and acceleration by counting the number of pulses sent by the output circuit, but the zero point must be reset at every new start.

 

Eltra has developed a broad catalog of incremental encoders here classified according to the type of mechanical mounting (solid vs blind/though hollow shaft) and the type of sensing technology (optical vs magnetic), with a wide range of resolution, flange and electronic outputs available to meet the specific application’s needs. 

Besides standard versions, Eltra offers to its Customers the possibility to customize and even develop custom-tailored devices in order to satisfy also the most peculiar requests and to provide 360° solutions. 

IDEA AND INNOVATION

Eltra ROTARY ABSOLUTE ENCODERS

Single- and multi-turn absolute encoder series

ROTARY ABSOLUTE ENCODERS

Eltra

Rotary absolute encoders provide a unique digital code for each distinct angle of the shaft, storing the value of the actual position and, therefore, preventing the loss of information in case of restart of the system or power-loss. 
Thanks to the advantages featured by this type of sensors, Eltra’s offer for absolute encoders in in constant growth, always in line with the latest innovations in technology.
Both singleturn and multiturn series are available among Eltra’s absolute enconders’ catalog, in order to extend the scope of application of transducers and to increase, at the same time, their flexibility and versatility, according to the Client’s requirements. 

The operating principle of single and multiturn encoders could be either optical, which guarantees a high resolution and is therefore recommended for applications that require more precision and accuracy, or magnetic, suitable for industries where elevated speed, IP protection sealing and excellent wear and temperature resistance are needed. The reliability and great performance that distinguish Eltra’s encoders remain a priority in the development of absolute encoders, with a variety of electronic and mechanic options available.
