Carlo Gavazzi announced the PH18 Series photoelectric sensors in a M18-rectangular housing. The housing has flat sides, and it can be mounted as a rectangular sensor via its two mounting holes. The new housing is rated IP67, IP69K and has an ECOLAB certification. Sensing ranges are fully adjustable via a potentiometer. Sensing modes include diffuse (1 m sensing range), retro-reflective (6.5 m sensing range), polarized retro-reflective (5 m sensing range) and through-beam (20 m sensing range).
