KJT-A3R Manually Adjustable Fiber Amplifier
- Product Model：A3R-N A3R-P
- Light source：Red, 4-Element Light Emitting Diode
- Respond time：Action, reset: 200µs each
- Power supply voltage：12 to 24 VDC ±10 %, ripple (P-P) 10 % or less
◆ High-performance fibre optic sensors suitable for detecting small objects and small chromatic aberration, adapting to the installation in
narrow space and bad environment.
◆ Fibre optic detector head is small, suitable for installation in narrow space, and the fibre optic head can work reliably in bad environments
such as large electromagnetic interference, large temperature difference, large humidity, and the need for explosion-proof occasions.
◆Simple operation and adjustable sensitivity.
