Elevator light grid AL2109-P-1820-3403/40b/49/143

• Low-profile, high resolution light grid for monitoring locking edges on elevators and accesses
• Thru-beam light grid with integrated controller
• In accord with EN81-70 and EN12015/16
• Dense monitoring field with up to 135 beams ensures that small objects are detected
• Object detection up to distance of zero
• Automatic beam crossing
• Insensitive to reflection and ambient light

The AL2109 elevator light grid is used to protect elevator doors or for passenger monitoring and access control. Its special features include its dynamic beam crossover with up to 135 active sensors, object detection down to nearly zero millimeters and an ambient light limit greater than 100,000 Lux. The evaluation electronics and the power supply are completely integrated into the emitter and receiver no external equipment is necessary for operation. The system offers flexible mounting options and meets the newest standards in accordance with EN 81-70 and EN 12016. Product Description
