This PDF file is the EI brand's M12 inductive sensor product manual, which introduces the features and characteristics of the product, including appearance, size, sensing distance, power supply, output type, protection functions, etc.
The EI series inductive proximity sensors are offered in stainless‑steel cylindrical housings with diameters of M12, M18 and M30. They are available in short or long versions and provide sensing distances from 2 mm to 15 mm. Power supply ranges from 10 VDC to 40 VDC, and the devices output either NPN or PNP transistor signals with make‑or‑break switching. Protection includes short‑circuit, reverse polarity and an IP67 rating.
Installation hints advise separating the sensor power cables from other power lines such as motor, contactor or solenoid cables to avoid interference from inductive voltage spikes. Cables should not be pulled or flexed repeatedly, and proper strain relief should be used. The document also lists ordering keys, dimensions, and wiring diagrams for each variant.
