ABB JOKAB SAFETY Introduces New Focus II Light Curtains and Light Grids
December 02 2013
ABB JOKAB SAFETY has introduced Focus II Light Curtains and Light Grids, an updated version of the Focus product line designed to offer the complete range of features in one low cost package. A single Focus II Light Curtain or Light Grid model can be used for all applications, eliminating the need to order or stock multiple versions for varying machine safety requirements, says the company. Light curtains and grids protect personnel from potentially hazardous machinery, robots or automated systems by creating a protection field with infrared beams, which, if interrupted, trigger a safety mechanism that immediately stops the machinery. Light curtains are typically used for inner area protection closer to machinery, with multiple beams placed between 14mm and 30mm apart. Light grids are for protecting areas further away from machinery, consisting of two to four beams placed between 200mm and 500mm apart.
Both Focus II Light Curtains and Light Grids meet the highest level of safety and have received all necessary national and international approvals. Focus II Light Curtains and Light Grids consist of two optical units, a transmitter and a receiver, which are continuously scanned, quickly detecting any objects that break the optical barrier. If any light beam is interrupted, the dangerous machine movement is stopped by the outputs from the light curtain.
