Recording position changes economically

Incremental rotary encoders are the most economic and simple way of measuring a position change (linear oder rotative) . Rotary encoders are particularly suited for low-cost applications since they can be used very flexibly in many applications.  In the product range of incremental rotary encoders SIKO offers flexibility not only of incremental interfaces but also of mechanical design.


Incremental rotary encoders with a variety of interfaces

The simple and cost-effective incremental rotary encoders (also known as rotary pulse encoders), offer an incremental interface with A, B, I as well as inverted signals. They are equipped optionally with HTL (push-pull) or TTL (RS422 – LD signals) . 

Optically or magnetically scanning incremental rotary encoders

Featuring two different scanning technologies, SIKO offers the ideal incremental rotary encoder for every application. Thus, highly precise optical scanning is available for applications that focus on accuracy and magnetic scanning for applications with very demanding ambient conditions.

The SIKO range of incremental rotary encoders is highly flexible regarding the choice of interfaces as well as mechanical complexity. Whether especially compact housing designs starting with Ø 28 mm diameter, rotary encoders with very high type of protection or also a wide temperature range of -40…+100°C – diversity knows nearly no limits. The incremental rotary encoders are available in hollow shaft design (up to 22mm) or solid shaft design.

Incremental rotary encoders may require referencing after startup since position changes are not recorded in the powerless state. If this is not desired, you can find a suitable alternative in the Absolute rotary encoders range of products.

Incremental encoders offer a vast diversity of applications

There is a large scope of applications for incremental rotary encoders. Thus, incremental rotary encoders feature a standard component in mechanical engineering nowadays. They are frequently being used for precise speed measurement and position monitoring in diverse applications including packaging plants, textile machines, printing machines, woodworking machines or asynchronous motors.
