φ6.5 Miniature Magnetic Proximity Sensor - NPN/PNP NO/NC (Smooth Barrel)
✨Features
Product Introduction
The phi 6.5mm Miniature Magnetic Sensor Series is a robust position detection solution designed for embedded industrial applications. Featuring a Smooth Barrel (Non-threaded) design with a standard 6.5mm diameter, it is easily installed into pre-drilled holes in machine bases, grippers, or pneumatic cylinder housings.
Unlike standard inductive sensors, this device detects magnetic fields, allowing it to sense targets through non-ferrous walls (such as aluminum or plastic) with a sensing range of 10mm. With comprehensive protection against short-circuits and reverse polarity, and a high switching frequency of 1000 Hz, it provides reliable, high-speed feedback for automated assembly lines and robotic systems.

FAQ
Q：How do I mount this 6.5mm smooth sensor?
A：A: Since it has no threads, this sensor is designed for "drop-in" mounting. You typically drill a 6.5mm hole (or slightly larger, e.g., 6.6mm) in your machine bracket. Secure the sensor using a set screw (grub screw) from the side, a split-clamp bracket, or industrial adhesive. This allows for a flush, low-profile fit.
Q：Will this sensor detect steel or aluminum parts?
A：No. This is a Magnetic Hall Sensor. It only detects magnetic fields. You must attach a magnet (like the standard phi 5x3mm NdFeB magnet) to the object you want to detect. It will not trigger on plain metal.
Q：I need to replace a sensor that sends a signal when the magnet is NOT present. Which model should I choose?
A：You likely need a Normally Closed (NC) model.
