				Detection output | 
			
				 
					NPN open-circuit collector transistor 
					  | 
		
| 
				output setting | 
			
				FG-40 has a unique "two-way output" (one of which can be set as input or output) | 
		
| 
				Operation output | 
			
				ON at detection or non-detection, can be set by keystrokes | 
		
| 
				Self diagnosis | 
			
				Output ON during unstable detection lasts for 40 ms, and output is cut off automatically when short circuit is output, and protection signal lasts until short circuit is removed.  | 
		
| 
				Reaction time | 
			
				Switching frequency: 10KHz, reaction time 50uS (up to 24us) | 
		
| 
				Detection distance | 
			
				Red light source: diffuse reflection detection distance: 400 mm (diameter 1 mm core) counter-fire detection distance: 1800 mm (diameter 1 mm core) Green light source: diffuse reflection detection distance: 400 mm (diameter 1 mm core) counter-fire detection distance: 1800 mm (diameter 1 mm core)  |

				Delay function | 
			
				0~9999ms optional | 
		
| 
				Transmitting power | 
			
				200% ,100%,50%,25%,12% the five of transmit power can be set by keys | 
		
| 
				Special Output 1 | 
			
				Rising edge pulse output and falling edge pulse output (pulse width is achieved by setting delay time) | 
		
| 
				Special Output 2 | 
			
				Interval output, counter output, two-point output, reverse output | 
		
| 
				Special input | 
			
				External control line (white), realize function: on-off threshold self-learning control |
