The ABB 2TLA822202R1000 is a Focus II FII-4-30-900 Type 4 safety light curtain — a transmitter-receiver pair with 30 mm resolution and a 900 mm detection zone, covering a 0.2 to 14 m operating range. The 30 mm resolution catches fingers and hands, making it suitable for press brakes, robotic cells, and assembly stations where point-of-operation guarding is required.
The 30 mm resolution defines the smallest object the curtain detects — a 30 mm diameter finger or tool entering the field triggers the safety output. The 900 mm detection zone is the protected height, so the curtain covers a 900 mm vertical span. The 0.2 to 14 m range means the transmitter and receiver can be spaced from 200 mm up to 14 m apart, covering both short-reach guarding and longer perimeter applications. Type 4 SIL 3 / PL e capability allows direct connection into safety-rated control circuits without additional fault-exclusion logic.
