ABB JOKAB SAFETY 佳可宝 Focus II - Safety Light Curtains and Light Grids 光幕

"Focus is a new version of our previous Light Grid\/Light Curtain Focus. Features such as muting and override are standard in all Focus Light Curtains and Light Grids. For Light Curtains, blanking and break functions are also standard. The optical sensors on Focus also have variable channel frequencies. The Focus units are Light Curtains\/ Grids with safety functions intended for applications where it is of great importance to protect persons from a dangerous machine, robot or other automated systems where it is possible to access to a dangerous area.","Focus creates a protection field with infrared beams. If any beam is interrupted the safety mechanism is triggered then the dangerous machine is stopped. Focus fulfills the requirements for non-contact safety equipment type 4 (Focus series) according to the international regulation standard EN 61496-1. Units are available with safety heights between 150 and 2400 mm. All electronic control and monitoring functions are included in the Light Curtain profiles. External connection is made via a M12 connection at the end of the profile. Synchronization between transmitter and receiver is achieved optically. No electrical connection between the units is required. Control and monitoring of the beam transmission is carried out by two micro-processors which also give information on the status and alignment of the Light Curtain via several LEDs."
