Product Introduction
The PRT12-4DO is an inductive proximity sensor with 2-wire DC design, operating voltage range of 10-30VDC and sensing distance of 4mm. Featuring M12 mounting size, it detects standard 12×12×1mm iron targets with 500Hz response frequency, capable of directly driving loads below 200mA. The built-in voltage fluctuation protection and reverse connection protection ensure stable performance in industrial automation applications.24
Key Features
This sensor adopts specialized IC design with enhanced anti-interference capability, offering 1.5-2 times longer detection distance than conventional models. The reinforced cable connection provides 9 times better bending durability with residual voltage below 3.5V and leakage current under 0.6mA. The visual operation indicator simplifies status monitoring, making it ideal for replacing mechanical switches. IP67 protection rating ensures reliable performance in harsh environments with oil, dust or moisture.617
Technical Specifications
With M12 sensing face diameter, the PRT12-4DO delivers 4mm standard detection range and 500Hz response frequency. Operating temperature ranges from -25℃ to 70℃ (-30℃ to 80℃ for storage) at 35-95%RH humidity. The brass nickel-plated housing provides excellent mechanical strength and corrosion resistance. Differential travel is 10% of sensing distance, with red LED for operation indication. Standard flexible cable ensures durability in continuous operation.1422
Applications
Widely used in machine tools, metallurgical equipment, chemical machinery, textile machines and printing systems for industrial automation. Performs precise position detection, stroke control, counting functions and equipment protection in automated systems. Particularly suitable for non-contact detection applications to prevent mechanical wear and enhance system reliability.1127
