The hollow shaft incremental encoders are used in production almost everywhere. However, for some cases, a special type of coupling is needed. Eltra Company produces a wide range of models with a hollow shaft, which provide not only reliable connection, but also measurement accuracy.

Features of eltra incremental hollow shaft encoder

The main task of an incremental optical encoder is to measure angular object displacement in space. Analysis of current location is based on data that is obtained by the interaction of infrared LED, wheels and receiver.

A feature of presented series is a special mechanical connection. Due to its design, such encoder can be mounted directly on another device shaft. This method will help to avoid using unnecessary parts during connecting. It allows hollow bore encoder safe and reliable interaction with the connected device shaft.

Additional structural reliability is achieved with the special locking couplings. They have different design variations that can be installed on the same model. There are several options for encoder`s coupling:

  • torque pin;
  • stator coupling;
  • blind hollow;
  • blind though hollow;
  • rear fixing;
  • front fixing;
  • adjustable flange;
  • with spring;
  • collar clamping.

Client can select the most suitable mounting direction, for example, radial or axial. Some models have different versions with rear and front mounting methods.

Types of incremental rotary eltra encoder with hollow shaft

The company has released many possible combinations of series and models. This allows clients to select the most suitable model for himself.

All created devices have small dimensions. Such compact size allows to their use in confined spaces. Very often, these sensors are used in all kinds of engines.

Device of presented series also known as eltra motor encoder are most often us in:

  1. AC servomotors.
  2. Gear motors.
  3. Motor feedback
  4. Elevators and stage machinery.

Like another optical sensors, devices in this category have excellent measurement accuracy. However, there is also need to set a reference point (so-called zero point), every time when turned on. When device is turn off, all information about current measurement will disappear.

Three channels are used here for data transmission. Signal comes in the form of square waves.

Eltra produces several types of incremental encoders with hollow shaft series:

  • with blind hollow shaft. It includes (EF 36 K, EM-ER 38 F / G, EH 53 A / B, EL-ER 53 A / B, EL-ER 58 F / G-63 F / G, EL-ER 72 A / B)
  • with through hollow shaft. EL-48 C/P, EL-49 C/P, EF-49 C/P, EH 50 FA/FP, EH-EL 88 P, EH 88 PE/PET, EL 120)
  • combined models with two variations. With blind or through hollow shaft. It includes (EL63 GB/FB/PB/PBF/PC/PCF; EH 80 C/K/P/PG; EF 80 C/P)

Company also created special kit rotary encoders series to which include EH 17-30M and EH 17-30.

In general, hollow-shaft incremental sensors are simple and precise device that can be easily placed right on the drive shaft.  A lot created models will allow client to choose the most suitable type of shaft and coupling.
