EZ-SCREEN (formerly known as EZ-GUARD) is a self-contained (no separate control box needed) safety light screen system.  Designed for both short and long range access/perimeter guarding, this two piece safety unit has an available sensing distance up to 70 m or 230 ft 

MICRO-SCREEN is suitable for most industrial applications, and takes up very little space. The tiny rectangular emitters and receivers measure only 32 x 25 mm (1/4"x 1"), and can be integrated perfectly into your products without being obtrusive.
