Product Details

The BLASI IR-Receiver ISR-LLA-B3 provides advanced infrared beam reception for Pantron through-beam light barrier systems protecting personnel around TA-6/TA-7 industrial doorways. Featuring slim anodized aluminum housing (12x12x60mm) matching IT-LLA transmitters, this LLA series receiver incorporates high-sensitivity pre-amplifier and daylight compensation circuitry to detect 880nm modulated IR beams, creating invisible protection zones interrupted by pedestrians, forklifts, or pallets during closure operations across wide equipment access points.

The B3 bayonet connector with gold-plated shielded contacts connects securely to TKHM-Z high-flex cables for signal transmission to ISM-2000/4000/8000 DIN-rail multiplexers, supporting multiple frequency channels to eliminate crosstalk across parallel beams safeguarding expansive door openings common in Dubai manufacturing facilities. Wide 25-30° reception angle maintains detection stability over extended distances while automatic gain control compensates for dust accumulation, lens contamination, and misalignment.

IP67 sealing of the IR-Receiver enables complete submersion during washdown procedures while -25°C to +70°C operation handles regional climate extremes. Protective front filter prevents lens damage while string-line alignment holes ensure precise transmitter positioning during commissioning. Exceptional 80,000 lux light immunity rejects sunlight, fluorescent lighting, and factory LED interference critical for reliable 8ms emergency stop response times.
