|
PNP/NPN Configurable |
Adjust and configure the output format, which can quickly adapt to changes in on-site deployment, but the wiring method needs to be repeatedly checked and tested for correct operation. |
||||||||
|
CH-A/CH-B Configurable |
Quickly switch between the optical synchronization encoding channels of two adjacent sensor sets, enabling rapid deployment of optically synchronized adjacent installations. Note that the transmitter and receiver of the same sensor set must use the same channel. |
||||||||
|
LONG/SHORT Configurable |
The receive sensitivity can be adjusted through configuration. For short-range applications, sensitivity attenuation can be quickly achieved to reduce the probability of interference. |
