LMX06-NS05 Inductive Proximity Sensor

The LMX06-NS05 is a cylindrical inductive proximity sensor designed for non-contact detection of metallic objects. With a sensing distance of 5mm, it is suitable for position sensing, counting, and speed monitoring in industrial machinery. The sensor features an NPN normally open output, operating on a 10-30V DC supply.

Technical Specifications

Housing diameter is 6.5mm (M6 thread) with a length of 45mm, making it ideal for compact mounting. The sensing face is made of PBT material, and the housing is nickel-plated brass for corrosion resistance. Output current capacity is 200mA, with short-circuit and reverse polarity protection. Switching frequency is up to 2000 Hz, allowing high-speed detection.

Environmental Ratings

The sensor is rated IP67, meaning it is dust-tight and protected against temporary immersion in water. Operating temperature range spans -25°C to +70°C, suitable for both indoor and outdoor industrial environments. The cable is 2 meters long, PVC insulated, with 3 wires (brown, blue, black).

Installation and Adjustment

Mounting is achieved via M6 nuts and lock washers. The sensing distance is factory set and not adjustable, ensuring consistent performance. The sensor has a built-in LED indicator for output status, simplifying commissioning and troubleshooting. Non-flush mounting requires a minimum clearance of 6mm from surrounding metal.

Compatible Targets

Standard sensing distance of 5mm applies to mild steel (Fe360). Reduction factors apply for other metals: aluminum (0.4), brass (0.5), stainless steel (0.7). For non-ferrous metals, the sensing distance may decrease; refer to derating curves in the datasheet.

Typical Applications

The LMX06-NS05 is commonly used in conveyor systems for object counting, cam position detection on rotating machinery, end-of-stroke sensing on pneumatic cylinders, and speed monitoring via ferrous gear teeth. Its small size fits tight spaces.

Electrical Connection

Wiring follows standard NPN configuration: brown to +24V DC, blue to 0V, black to load (PLC input or relay). The load must be connected between black and +24V. The sensor's low leakage current (0.5mA maximum) ensures compatibility with most PLCs.

Conclusion

The LMX06-NS05 inductive proximity sensor provides reliable metal detection with a 5mm range in a compact M6 package. Its IP67 rating and wide temperature range make it a versatile choice for factory automation.
