Product Description

LM18 Analog Inductive Proximity Sensor

Cylindrical M18 Sensor for Non-Contact Metallic Object Detection

The LM18 series is a cylindrical, analog inductive proximity sensor designed to detect metallic objects without physical contact. It is commonly used in industrial automation for position sensing, speed monitoring, and metal part detection. The "LM" designation indicates it is an inductive sensor [citation:2].

NonContact Sensing Detects metal objects without physical contact, ensuring long service life [citation:7]
Analog Output - Provides a variable signal (voltage or current) proportional to the target's distance [citation:6]
The sensor is housed in a metal M18 x 1 threaded cylinder [citation:3][citation:4]
It is available in shielded (flush) and nonshielded (nonflush) mounting options [citation:3][citation:4]
This device is sensitive to ferrous metals (iron, steel) and has reduced range for non-ferrous metals like aluminum or copper [citation:6]

Troubleshooting

No output signal:

  • Check power supply voltage matches the sensor specification (e.g., 10-30V DC) [citation:4]
  • Verify correct wiring (NPN/PNP) and load connection
  • Ensure the target is within the specified sensing distance [citation:3]

Inconsistent detection:

  • Confirm target is a ferrous metal; reduce distance for aluminum/copper [citation:6]
  • Check mounting: non-shielded sensors need more clearance from surrounding metal [citation:3]
  • Inspect sensing face for debris or damage
