Feature：
🔌【Independent Capacitive Proximity Switch】 The switch is designed as an independent type, with a NPN normally open mode capacitive proximity switch. This makes it easy to install and use with 3D printers.
🔌【Long Wiring Length】 With 470mm wiring length, the proximity switch can detect objects up to 5mm away with stable and reliable performance.
🔌【Sturdy and Durable】 The switch housing is made of nickel-plated brass and the external sensing is made of ABS material, making it strong and durable.
🔌【Versatile Object Detection】The sensor proximity switch can detect various materials, including metals, non-metals such as plastic, glass, wood, and liquids such as water and oil. This makes it useful for different applications in 3D printing.
🔌【Applicable Models】This capacitive sensor proximity switch is specifically designed for use with 3D printers, particularly ET4 series and ET4/4 Pro models. It provides precise auto-leveling for your 3D prints.
