Siko AH3650M Absolute encoder
Sku: SIK-AH3650M
Compact rotary encoder with hollow shaft and analog interface
Product Information
The AH3650M rotary encoder is an absolute magnetic single- and multi-turn rotary encoder, which impresses with its extremely compact design. It is particularly robust and resistant to vibrations. Thanks to its high degree of protection up to IP67 and a temperature range of -40° C … +85° C, it is also suitable for demanding industrial applications. The particularly small design with a diameter of only 36 mm predestines the rotary encoder for use in applications with limited installation space. The analog current or voltage outputs can be taught to any measuring range thanks to the teach-in.
- absolute wear-free magnetic encoder
- Multiturn without gearbox and without battery
- current or voltage output interfaces
- extremely compact and very robust design
- IP67 protection class
- extensive temperature range -40 … 85° C
- optimal price-performance ratio
