Micro sized inductive sensors are a series of sensors developed and manufactured for electronics, machine tools, robot manufacturing, and other small devices. Its dimensions range from Φ 3 mm, Φ 4 mm to Φ 12 mm, and the series is complete; And it can provide split structure micro sensors, with a minimum probe size that can be reduced to Φ 3 mm and a length of up to 12mm. Multiple standard probes can also be provided for different applications to choose from. The entire series can provide DC 24VDC power supply, PNP or NPN output. The response frequency reaches 2500Hz, with short-circuit protection, reverse polarity protection, and surge protection functions.
