Need a reliable sensor for automation or machinery?
This is the XS8S173NAL2C, an inductive proximity switch.
In simple terms, it detects metal objects without touching them.
This specific model is an NPN type (a common output configuration) and operates on 12-24VDC power, which is standard in many industrial controls.
Its sensing range is 5mm, meaning it can detect a metal object when it comes within 5mm of the front face.
The sensor body is a compact 17mm by 17mm square, so it fits in tight spaces.
It's part of a family of sensors (like the XS8S173NBL2C, PNP versions XS8S173PAL2C/PBL2C), so make sure this NPN version is right for your circuit.
These are often used as flow switches or part of safety and detection systems in factories, packaging machines, you name it.
They're workhorses – durable and designed for repetitive, accurate detection.
If you're replacing a sensor or building a project and need non-contact metal sensing, this is a solid, professional-grade component.
Just double-check your required voltage, output type (NPN), and detection range.
