H1941

The H1941 is designed as opto-hybrid ICs specially for transmission or reflection-mode photoelectric relays using infrared LEDs and PIN silicon photocells. H1941 is a light-emitting hybrid IC. Since the conbination of it is synchronized transmission-mode operation at a distance as long as 5 meters is possible. When used as reflection-mode photoelectric relay, it is capable to detect the distance to the object.

H1941 has four features. The first one is operatable distance is 0 to 5 meters. The second one is not influenced by background light due to synchronized operation. The third one is sensitivity is adjustable precisely. The fourth one is operation requires minimum external components. That are all the main features.

Some absolute maximum ratings of H1941 have been concluded into several points as follow. The first one is about its source voltage which would be 13V. The second one is about its power consumption which would be 220mW. The third one is about its operating temperature range which would e from -10°C to +55°C. The fourth one is about its storage temperature range which would be from -20°C to +65°C.

And also some characteristics about H1941. The first one is about its current consumption which would be typ 55mA. The second one is about its driver terminal voltage which would be typ 1.7V. The third one is about its emission time which would be min 40us and typ 50us and max 60us. The fourth one is about its emission interval which would be min 370us and typ 430us and max 490us. The fifth one is about its sync. output resistance which would be typ 20K. That are all the main specifications above. And so on.
