Product Description And Features
The LF18 square inductive proximity sensor is a popular choice in the market, known for its reliability and enhanced features compared to the market model SN04. One of the significant upgrades is the fully upgraded internal circuit board, which contributes to a longer service life. Additionally, the LFD18 series, an extension of the LF18, comes with dual indicator lights. These lights clearly display the Power-on status and sensing status, making it easier to monitor and manage during daily operations. This makes the sensor not only more durable but also more user-friendly.
This sensor provides a 5mm sensing distance and supports multiple output modes, including NPN, PNP, 2-wire DC, to accommodate various control system needs. It comes with a 2-meter cable and is rated IP67, ensuring stable operation even in harsh industrial environments, withstanding temperatures ranging from -25°C to 70°C.
