Looking for a reliable sensor for your automation project? This Heschen square proximity sensor (model PL-08N3) is a solid choice. It's an inductive type, so it detects magnetic metals (like steel) from up to 8mm away. For non-magnetic metals (like aluminum), the range will be a bit shorter. It works with a 10-30VDC power supply and can handle up to 200mA of current. The output type is NPN, which is super common, and it gives you both a Normally Open (NO) and a Normally Closed (NC) signal on its 4 wires – pretty versatile for wiring into different control systems. It's a non-shielded (non-flush) type, so you need a little space around it when mounting. The body is small, just 17mm x 17mm x 35mm, made of ABS plastic, and it can handle temps from -25°C to +60°C. It's CE certified too. Great for use on CNC machines, conveyor systems, or anywhere you need to detect the position of a metal part automatically.
