What are position sensors?

Position sensors essentially are composed of three different products: the sensors themselves, position transmitters that can be used virtually anywhere and displacement encoders. All these products check and monitor automated motion sequences and are therefore indispensable in industrial application processes.

Festo position sensors

Complex or programmable solutions are also available as position sensors, and can only be used for the drives for which they have been optimised. This also applies to the Festo position sensor SRBS, which is used to detect a rotary movement of the shaft on the rotary drives DRVS and DSM. Features of the SRBS are:

  • The sensor can be quickly mounted without having to manually search for switching points
  • No need for a connecting cable, as the sensor contains 2 switching points
  • 2 switching outputs with 24 V
  • Sensing range > 270°
  • Sturdy, non-contacting and encapsulated position sensor with long service life

Also in our product portfolio is the position sensor SMH for our grippers HGD / HGPP / HGR and HGW. The sensor must be connected to an evaluation unit and is based on the magnetic Hall measuring principle. Depending on the gripper position, an analogue electrical signal is generated in the position sensor. The conversion to 2 digital output signals (corresponding to 2 gripper jaw positions) is performed using signal converters SVE4.

Festo 位置变送器

位置变送器一般用于在特定检测范围内对活塞运动进行模拟反馈,应用范围包括超声波焊接、压装、拧螺栓、夹紧、合格/不合格检测等。位置变送器可在检测范围内检测活塞磁铁的磁场,并以较高的位置重复精度进行评估。通过标准化 0 ~ 10V、4 ~ 20-mA 模拟信号或通过 IO-Link 提供信息。此外,这类设备还提供编程选项,可直接在变松器中对信号信息进行预评估。

Festo 为您提供四种位置变送器,所有变送器均基于磁性霍尔测量原理,但在规格上有所不同,因此检测范围也有所不同。小型位置变送器 SDAS-MHSSMAT-8M 是紧凑型气缸和抓手的理想解决方案。SDAS-MHS 还提供直接在设备上编程设置两个切换点的功能。这样无需在小型执行器上安装第二个气缸开关。SDAT-MHS 是通用解决方案,检测范围可达 160mm,0 ~ 10V、4 ~ 20mA、IO-Link、配备一个可编程式切换输出端。Festo 位置变送器提供精确结果,可与气动元件和应用出色结合,可靠性亦十分出众。

Festo 位移编码器

位移编码器用于测量物体与所选参考点之间的距离,也用于定位任务。Festo 产品组合包罗万象,可满足各种要求。

我们提供基于磁致伸缩测量原理的位移编码器 MME-MTS-TLF,它支持全感应式绝对测量。此产品是一款支持用户使用较高移动速度的导电塑料电位器。MME-MTS-TLF 主要应用于气伺服定位技术和软停止。

另外一款是位移编码器 MLO-POT-LWG – 一款具有高分辨率的绝对测量型拉杆式电位器。此产品配备插拔式接口,适用于 100 ~ 750 mm 行程。特点是使用寿命长。

Festo 位移编码器 MLO-POT-TLF 不但支持高移动速度,而且具有较长的使用寿命。这是一款具有高分辨率的绝对测量型导电塑料电位器,配备插拔式接口,可用于 225 ~ 2000 mm 行程范围。
