New Original Keyence EH-305 Proximity Sensor<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The EH-305 is a compact, high-performance separate amplifier proximity sensor manufactured by Keyence, belonging to the EH series inductive proximity sensor lineup. This model adopts a split structure, separating the sensor head and signal amplifier unit to adapt to narrow installation spaces, high-temperature working environments and limited wiring layouts. It detects metal objects without physical contact based on electromagnetic induction principle, featuring stable detection for iron, aluminum, copper and other conductive metals. As a new original industrial-grade sensor, it supports long-distance signal transmission, strong anti-interference capability against inverter, motor and electromagnetic equipment interference, and is widely applied in automated assembly lines, CNC machine tools, packaging machinery, robotic positioning, conveyor counting and metal workpiece presence detection scenarios.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Non-contact metal detection: Identify ferrous and non-ferrous metal targets without mechanical wear on sensor head and workpieces.<\/li>\n
  2. Long-distance signal transmission: The cable between sensor probe and amplifier can extend up to 10 meters without signal attenuation.<\/li>\n
  3. Dual output switching mode: Built-in NPN and PNP switching output, compatible with mainstream PLC, relay and industrial controller input terminals.<\/li>\n
  4. Adjustable detection sensitivity: Rotatable sensitivity knob on amplifier module to fine-tune detection range for different metal materials.<\/li>\n
  5. Fault self-diagnosis function: Integrated LED indicator lights for power supply status, detection trigger signal and wiring error alarm.<\/li>\n
  6. Reverse connection protection: Built-in circuit protection to prevent damage caused by positive and negative power wiring reversal.<\/li>\n
  7. Overload and short-circuit protection: Automatic circuit cut-off when output terminal short-circuit or overload current occurs.<\/li>\n
  8. Wide voltage range operation: Supports universal DC power supply to match different industrial control power modules.<\/li>\n
  9. High-speed response output: Ultra-short response time to capture fast-moving small metal parts on high-speed production lines.<\/li>\n
  10. Multi-environment adaptability: Waterproof and dustproof sealed probe design for workshop, warehouse and semi-outdoor industrial environments.<\/li>\n<\/ol>\n<\/div>\n

    Key Technical Features<\/h3>\n<\/div>\n
    \n
      \n
    1. Split modular design: Miniature cylindrical sensor probe occupies tiny installation space; separate amplifier can be mounted on control cabinet for easy adjustment and maintenance.<\/li>\n
    2. Material compensation technology: Internal circuit automatically compensates detection distance deviation caused by different metal target conductivity.<\/li>\n
    3. Noise suppression circuit: Built-in filter circuit eliminates interference from frequency converters, servo motors and high-power electrical equipment nearby.<\/li>\n
    4. High mechanical stability: Stainless steel sensor probe housing resists collision, scratch and chemical fluid splashing.<\/li>\n
    5. Low power consumption design: Standby power consumption lower than 20 mA to reduce overall equipment energy consumption.<\/li>\n
    6. Visual status feedback: Three-color LED indicators clearly display power on, detection triggered and abnormal wiring status at a glance.<\/li>\n
    7. Vibration resistance structure: Internal components fixed with shock-absorbing adhesive, stable operation under equipment vibration up to 10 to 500 Hz.<\/li>\n<\/ol>\n<\/div>\n
