BLASI – Light barrier ELS 300 Reciever ELS 300 – NPN/LO

The BLASI – Light barrier ELS 300 Receiver ELS 300 – NPN/LO pairs with matching transmitter to create multiple invisible infrared curtains within revolving door drums, instantly signaling FlipFlow controllers to halt wing rotation upon detecting pedestrians, carts, or obstacles during high-traffic operation. Certified to EN 13849-1 Category 2 / Performance Level C, the NPN open-collector output activates <20ms upon beam interruption while LO (Light-ON) configuration maintains safety signal during normal unobstructed rotation phases across two-wing security, three-wing standard, and four-wing high-capacity configurations.

Operating on 10-30VDC auxiliary supplies common in BLASI control circuits, the receiver consumes <10mA while providing 50mA drive capability for redundant safety relays and PLC inputs. Integrated controller eliminates external amplifiers while M8 4-pin connector delivers plug-and-play integration matching FlipFlow safety wiring standards. Compact 12mm diameter housing snaps into factory-drilled drum profiles with ±5° paraxial detection maintaining coverage despite minor misalignment from years of mechanical wear.

Multi-color status LEDs of BLASI – Light barrier, confirm power, output state, and contamination alerts visible through drum wall cutouts while 100,000 lux ambient light immunity prevents false tripping from mall lighting and sunlight penetration. Rugged IP65 plastic enclosure withstands cleaning chemicals, vibration from adjacent drives, and -20°C to +60°C temperature swings typical in Dubai commercial entrances. Field technicians value networkable Y-splitter capability for multi-beam configurations, integrated polarity protection, and exact compatibility with all FlipFlow firmware revisions ensuring uninterrupted safety compliance worldwide.
