LM18 Inductive Proximity Sensor
VIOX’s LM18 Inductive Proximity Sensors: Compact, high-precision sensors for metal object detection without contact. Available with sensing distances of 5mm and 8mm in flush and non-flush types, they operate within 10-30VDC and 90-250VAC ranges. Featuring NPN, PNP, and two-wire outputs, these durable metal-cased sensors offer IP67 protection, 200Hz/25Hz response frequency, and operate in -25℃ to +75℃ environments. Ideal for manufacturing, automotive, conveyor systems, packaging machinery, and agriculture.
