SH4 Safety Light Curtains A/P Models


Datasensing announces the addition of new models to SH4 Series, making it the most complete series of safety light curtains on the market.
In addition to finger, hand and body protection models based on emitter and receiver operating principle, also body protection models based on one active and one passive units will be available.

The new models SH4 AP cover Base, Standard Muting and Advanced functionalities, and correspond to the traditional 2, 3 and 4 beam light curtains, with 500, 800, 900 and 1200 mm heights.

The main advantage of SH4 AP models is that only one side of the pair needs to be connected to the power supply. This results in less expense in material and installation time. It is ideal for applications that require body protection and operating distances of up to 8 meters.

In addition to introducing new models, also SH4 Body Advanced will be improved by integrating an LED aimer for each beam. This will make it easier to align them over long distances and in applications that require the use of mirrors.
