SIKO AV58M Series

An absolute position, multi-turn, user programmable, encoder with shaft coupling.

The new SIKO AV58M adapts to your specification.
With this fundamental principle, SIKO GmbH has enhanced its product programme to include a robust, magnetic, absolute analogue encoder with teach-in function that will forge new paths within the international encoder market.

Using two buttons on the reverse and two external inputs, the AV58M can be set to your measuring range in just a few steps. Thus you program the full signal travel distance (0 … 10 V or 4 … 20 mA) to precisely the measuring range specified. Irrespective of whether you want to measure 2, 10, or 100 revolutions, the AV58M is the best choice you could make.

The AV58M encoder measuring range is 12 bit resolution (4096 increments).
The measuring technology is robust wear-free, battery-free, single and multi-turn.
Thanks to double ball bearings, this low-cost encoder is designed for high loading.
These features provide the AV58M with a large installation base in all manner of applications.

Two programmable models cover every measuring angle or length.

  • AV58M multi turn with 0~10Vdc output
  • AV58M multi turn with 4~20mA output
  • Just 2 models to cover hundreds of applications.

SIKO AH25S Series
SIKO deliver robustness and accuracy for Construction and Agricultural Machinery!
When it comes to construction machinery, whether in the field of agricultural technology or forklift trucks, design engineers are often stretched to their limits with existing rotary encoders and measurement systems, as things tend to get especially tight in each of these application scenarios. Finding just the right system, one which satisfies all technical requirements, is resilient, and which also offers just the right construction form, often proves to be an impossible balancing act.
This is seen time and time again in the field of mobile automation as there are many factors to be contended with. Regardless of jolts, vibrations, dirt or moisture, all measurement tasks would always have to be done very accurately and free of any and all disturbances. In order to meet all requirements, the measurement systems are often elaborately encapsulated so as to be able to withstand weather conditions. However, the difficulty here is that the size of the measurement systems often exceeds the available installation space.

The miniature single-turn AH25S absolute rotary encoder from SIKO is the cost-effective and flexible option.
It provides a unique balance between high resolution, excellent functionality, a sturdy housing design and a minimal construction form.
The cost-effective AH25S rotary encoder can be used in a number of ways. You can choose from several analog interfaces such as 4…20 mA, 0…10V or 0.5…4.5V, which is especially suited for agricultural equipment. The rotary encoder always makes use of the advantages of the wear-free magnetic measurement principle, thus resolving the entire 360° into 4096 measurement steps. A redundant version is also available upon request. This innovative technology, packaged in a sturdy die-cast case, can be made use of in applications with limited installation space thanks to the small case diameter measuring only 25 mm.
Special design measures ensure Protection Class IP65 over the course of a long product lifetime, which makes the rotary encoder particularly suitable for positioning tasks in mechanically demanding environments and with temperatures ranging from -40 to +85°.
Combined with resilient ball bearings, the AH25S is ideal for dependable measurement under confined spatial conditions. The 8 mm blind hollow shaft enables a simple installation of the rotary encoder. The rotary encoder itself can be manufactured with a radial cable outlet with an open cable end or a corresponding customer connector.

The rotary encoder AH25S is a magnetic miniature single-turn absolute encoder with an analogue output. This rotary encoder with its robust die cast housing was designed especially for use in mobile machines and has an absolute range of 360°. With its extremely compact size (ø25 mm) it is predestined for applications with very limited space.
