位置和运动传感器specialist POSITAL has announced that its family of absolute IXARC rotary encoders has been expanded to include support for the popular IO-Link communications interface.
IO-Link是一种低成本，易于实现的通信系统，旨在简化位于工厂地板上的大规模田野或工业以太网网络与传感器或执行器设备之间的连接。在IO-Link Master Gateway设备的一侧是植物整个网络的接口，而另一侧具有与单个传感器设备的多点对点连接。最终设备的IO-Link接口相对简单，消除了在传感器/执行器级别支持复杂通信协议的需求。IO-Link支持各种数据类型，包括测量数据，设备配置指令和有关操作条件参数（例如温度）的信息。
IXARC encoders, based on POSITAL’s high-precision magnetic measurement technology, are very well suited to IO-Link implementations. They are compact, easy to install, and provide highly reliable performance, even under harsh industrial conditions. Two versions of IO-Link connected encoders will be offered: single-turn (360 ° range, 14 bit resolution) and multi-turn (up to 1 billion revolutions). Single-turn variants can be converted to operate in incremental mode by making use of a different pin-out arrangement in the connector.
多转向型号具有几个令人兴奋的新功能，包括16位分辨率，直接输出旋转速度直接向控制器输出旋转速度以及添加电子凸轮/预设/重置功能，从而利用通过连接器的引脚2传输的二进制数字信号。也有扩展的设备诊断。多转编码器中内置的温度和振动传感器可以监视这些条件参数。多转弯模型上的旋转计数器由设备轴的旋转从能量收获（通过Wiegand效应）提供动力，从而确保旋转计数始终是最新的，即使在无法使用电源的动力时发生运动时也是如此。这消除了对备用电池的需求，并有助于降低维护成本。
与其他上质IXARC编码器一样，IO连接的传感器将提供各种住房材料，环境保护水平（高达IP69K），轴类型/直径和安装法兰。这意味着客户可以以迅速而有竞争力的成本配置具有正确的机械和性能特性的传感器。Postital使客户轻松找到右IO-Link编码器用于其特定应用程序。产品查找器工具www.posital.com使客户能够指定其项目所需的产品功能，并在最合适的产品中快速零
POSITAL IXARC encoders with IO-Link interfaces will be introduced at the SPS trade show in Nuremberg, Germany (November 26 to 28) and at the IREX exhibition in Tokyo (December 18 to 21). They will be available in sample quantities at the end of 2019.
