Overview

The W12-3 family features a complete range of photoelectric sensors that are enclosed in a metal housing. There are a large number of variations that are available, including proximity, retro-reflective, through-beam, special laser and clear material versions. These sensors offer many advantages over conventional optical sensors due to their reliable object detection and monitoring capabilities. Whether in packaging, pharmaceutical, or the food and beverage industries – the W12 family provides a solution for any application.
