Added to Your Cart:
The safety light curtain can be flexibly integrated into systems thanks to the well-conceived mounting technology and the compact housing. Alignment of the emitter and the receiver is simplified by the visible red light and the signal strength display. The user-friendly wTeach2 software makes settings and diagnosis via the IO-Link interface extremely easy. Settings can be subsequently saved to a microSD card and quickly duplicated on other products. Extensive muting functions guarantee an ideal solution for every application in order to safely transport objects into and out of the danger zone.
