robust absolute single-turn rotary encoder
![](/fileadmin/_processed_/0/c/csm_27865_ANALOG_3836ce3403.jpg)
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.
- Miniature absolute analog encoder
- 12 bit (4096) resolution over 360°
- IP65 protection class
- -40 … 85° C operating temperature
- Voltage (0 … 10 V, 0.5 … 4.5 V), current (0 … 20 mA, 4 … 20 mA) outputs
- Easy mounting by hollow shaft ø8mm
