The attachment location depends on the Spann-Box® type. In most cases, the limit switch is attached on the side. The contact is triggered by a cam switch attached to the slide profile. In the case of some models (types K-L and SR -L), the contact is achieved directly via the tension core by means of an opening in the housing.
Limit switches attached on the side are not suitable for the Spann-Boy®, for example. In this case, a limit switch mounted on top is used instead. The contact is actuated when the pressure pin on the tension core is reached.
If you decide on a Spann-Box® or Spann-Boy® design, please contact us. We will happily provide detailed advice on a range of custom options.
