Output Responsive to metal Options: proximity. NPN Connection: 4 mm Housing Body: +2.3V to +27V Package / Case 5 µA max. Interface: Shielded Indicator: Since 1973 Normally Closed (NC) or Normally Open (NO) Cable leads. 2-Wire Metal Cylinder, threaded, M18 None None Description: M18M2 series 2-wire True-Off™ LPS(Inductive Proximity Sensor)operates at the industry’s lowest off-state leakage current or residual current (3 µA) level and lowest power supply voltage levels (+2.3V to +27V), making it ideal for low current portable/battery operated applications. The low minimum operating voltage of +2.5V also makes this sensor directly compatible with most types of computers for portable robotics, motor controls, and automation. Utilizing CMOS IC sensor technology, this sensor provides excellent results, even with difficult-to-detect objects, e.g. small or thin parts, or bright metals. Features: PATENTED USA 9,140,579  Ultra-low off-state leakage current: 3 µA typ. Outperform competitors’ 456 µA. As the name implies, It is a True-Off™ when off. To see the video demonstration, please search “M18M2” at YouTube.  Ultra-low on-state holding current: 20 µA min.  Low power supply voltage: +2.3V to +27V MERCURY www.MercuryUnited.com U.S.A.: TEL (1)-909-466-0427, e-mail: sales-us@MercuryUnited.com Mercury Page 1 of 4 Oct. 30, 2019 Ver.3.0 Micro Power Inductive Proximity Sensor M18M2 Series MERCURY 2-Wire True-Off™ Industry’s Lowest 3 µA (typ.)

Note 1 Correction Factors -A percentage of the rated operating distance (Al) that represents the operating distance for targets constructed from materials other than Aluminum. Deviations maybe due to variations in the oscillator frequency, alloy compositions, purity & target geometry. Note 2 Normally Closed (“NC”): The output is OFF when the target is detected by the sensor. Note 3 Sensing Distance: A distance at which the target approaching the sensing face, along the reference axis, causes the output signal to change.
