AksIM线路板级磁编码器专门设计用于集成到空间有限、无法安装带T形外壳的传统AksIM读数头的应用。外壳（由客户提供）必须对磁编码器起到安全保护作用。

该线路板级磁编码器系统包含一个轴向磁化的圆环和一个读数头线路板。

磁编码器具有内置的高级自监

控功能，可持续检查几个内部参数。错误报告、报警以及其他状态信号可从所有数字接口获得，并且可通过板载LED指示灯进行观察。

三、应用领域

磁编码器系统适合工业和YL应用

典型应用包括：机械臂关节，其馈电电缆穿过磁环

或精密变速箱，其主传动轴上安装有磁环

此外，还提供针对 OEM 集成的定制读数头线路板设计服务

AksIM-2 is a non-contact high
performance off-axis absolute
rotary encoder designed for
integration into space-constrained
applications. A hollow ring, true
absolute functionality ａnd high
speed operation make this encoder
suitable for many applications.
The AksIM-2 encoder system consists
of an axially magnetised ring ａnd a
readhead.
The encoders come with SSI,
BiSS ａnd asynchronous serial
communication interfaces ａnd offer a
range of binary resolutions to 20 bits
per revolution.
The encoder operates from -30 °C
to +85 °C or -40 °C to +105 °C
with extended temperature range
option ａnd is resistant to shock and
vibrations.
The AksIM-2 encoder has a built-in
advanced self-monitoring function,
continually checking several internal
parameters. Error reporting, warnings
and other status signals are available
on all communication interfaces and
are visualised with the on-board LED.
The AksIM-2 encoder system is
suitable for use in industrial and
medical applications.
A typical application is a robotic arm
joint with a cable feed running through
the ring or a precision gearbox where
the ring is attached onto the main
transmission shaft.
Custom design service for OEM
integration is also available.
