Autonics PRE12-4DN inductive proximity sensor is a cost-effective detection solution developed for industrial applications. Featuring stainless steel housing with abrasion-resistant surface treatment, this cylindrical device (12mm diameter × 40mm length) combines compact dimensions with robust construction, making it suitable for space-constrained installations in machinery and equipment.
Operating on high-frequency oscillation principle, the sensor achieves non-contact detection of ferrous metal targets with 4mm sensing distance. Its built-in temperature compensation circuitry ensures stable performance across wide temperature range (-25℃ to +85℃), accommodating applications in refrigeration systems and outdoor equipment. The NPN normally-open configuration with 3-wire connection supports mainstream control systems, delivering 200mA output capacity for standard industrial loads.
Engineered with electromagnetic interference resistance, the optimized circuit design minimizes signal interference in densely installed equipment clusters. The IP67-rated enclosure provides effective protection against dust ingress and temporary water immersion, maintaining reliability in environments with oil mist or occasional splashes. Dual-color LED indicator offers instant operational status feedback through red/green illumination, simplifying commissioning and maintenance procedures.
This model excels in position detection for automated production lines, robotic arm motion verification, and conveyor belt material monitoring. Proven applications include packaging machinery, injection molding equipment, and CNC machine tools. Available with fixed cable or connector-type wiring options, the oil-resistant PVC cable jacket extends service life in lubricant-rich environments. For optimal performance, professional mounting brackets are recommended to ensure precise alignment, while regular cleaning of the sensing surface helps maintain detection sensitivity.
