Panasonic PM-U25 Photoelectric Sensor :
The Panasonic PM-U25 is a versatile and high-performance photoelectric sensor designed for precise object detection in a range of industrial environments. With a sensing range of up to 2.5 meters, it ensures reliable and accurate detection even over longer distances. The sensor utilizes through-beam technology, providing a stable and consistent output for high-precision applications.
This sensor features a NPN output, with a response time of less than 1 ms, allowing for fast and efficient detection. It operates within a voltage range of 10-30 VDC, supporting light and dark operation. The IP67-rated housing offers protection against dust and water, making it ideal for harsh and demanding industrial environments. Additionally, the M8 4-pin connector ensures a secure and easy installation process.
