PM8-01N-M8 Full Metal Proximity Sensor Product Description
Product Overview:
The PM8-01N-M8 is an industrial-grade proximity sensor featuring an all-metal construction, designed for metal object detection based on electromagnetic induction principle. With M8 threaded housing and 3-wire NPN output configuration, this sensor integrates high-sensitivity detection components to deliver reliable non-contact metal detection in demanding industrial environments. The precision-machined 304 stainless steel housing combined with epoxy resin sealing technology ensures exceptional mechanical durability and environmental resistance.
Technical Features:
• Full-metal encapsulation: Monolithic stainless steel housing provides 200% higher impact resistance than plastic counterparts, effectively withstanding mechanical shocks and vibrations
• Embedded installation: Compact design (8mm diameter, 40mm length) supports flush mounting for space-constrained industrial equipment
• Intelligent detection system: Built-in temperature compensation circuit maintains consistent sensing distance within -25℃ to +70℃ operating range
• Enhanced EMI resistance: Optimized electromagnetic shielding withstands 30V/m interference, ensuring stable operation near inverters and motors
• Industrial protection: IP67-rated enclosure prevents dust ingress and liquid penetration
Application Scenarios:
Ideal for industrial automation systems requiring metal component positioning, including CNC machine tools, packaging equipment, and robotic arms. Capable of detecting both ferrous (steel, iron) and non-ferrous (copper, aluminum) metals. Typical applications include conveyor belt monitoring, safety door position sensing, and robotic arm motion control.
Operational Advantages:
Through optimized coil winding and signal processing algorithms, the sensor achieves 800Hz response frequency while maintaining 1.5mm standard detection distance, suitable for high-speed object detection. Dual-color LED status indicator with 360° visibility facilitates on-site debugging. Standard PUR cable jacket withstands 800,000 bending cycles, compatible with 0.2-1.5mm² conductors.
