On the tech details page, I found some interesting components highlighted. The first one was a domestic switch needle labeled as KG-300K, which features a needle head diameter of 3.0mm and is designed for normally open switches. Following that, there was mention of a 100V, 250mA surface-mount high-speed switching diode. Next up was a photocoupler, which plays a crucial role in isolating signals between circuits.
To give you a better visual, there’s an image carousel showing these components with detailed descriptions beneath each slide. The first slide has an image (though the link is currently broken), describing the KG-300K switch needle. The second slide talks about the switching diode, while the third slide highlights the photocoupler. Below the main slides, there are thumbnail images for navigation, but again, the links seem inactive at the moment.
Moving on to the application side, there’s a discussion about the wiring diagram for a photoelectric switch sensor using a three-wire DC setup. This particular sensor operates within a voltage range of 10-30V DC. It features a normally open contact (NO) with a voltage drop of less than or equal to 1.8V. Additionally, it offers short-circuit protection and complete polarity protection. When connecting sensors in series—whether they’re part of a three-wire or four-wire DC series—the total voltage drop increases, and so does the cumulative delay time for each sensor.
For a clearer understanding, there are two images provided. One shows the wiring diagram for the three-wire DC photoelectric switch sensor (image link: http://i.bosscdn.com/blog/20/13/12/24175616726183.jpg). Another image (link: http://i.bosscdn.com/blog/20/13/12/24175617983355.jpg) provides a circuit schematic for the same setup.
In practical applications, always ensure proper connections and voltage checks to avoid any potential issues. These components are widely used in automation systems and industrial controls where precise sensing and signal isolation are critical.
