Garantta miniature inductive proximity sensor is a compact square-type metal detection sensor. Adopting an inductive electromagnetic principle, it realizes non-contact sensing for all ferrous and non-ferrous metals. With ultra-small size, slim structure, and high integration design, it is perfectly suitable for installation in narrow and limited spaces. Built-in multiple circuit protection, strong anti-interference ability, stable & long-lasting performance for industrial automated environments.
Key Features
- Ultra miniature & compact square housing, easy installation in tight spaces
- Non-contact metal detection, no wear and long service life
- High sensing stability and strong anti-electromagnetic interference
- IP67 waterproof, dustproof and oil-proof for harsh workshop conditions
- Reverse polarity, short circuit and surge protection
- Fast response speed, high detection accuracy
- Wide working voltage, compatible with mainstream industrial PLC
Product Advantages
- Small size with stable sensing performance, solving installation limitations of mini automation equipment
- Fully sealed structure, adaptable to dust, moisture and oil mist working environment
- Low power consumption and high shock resistance, suitable for long-term continuous operation
- Multiple output types optional: NPN / PNP, NO / NC
Application
- This Miniature Inductive Proximity Sensor is widely used in small and precision automation equipment:
- Precision machinery and 3C automated production lines
- Electronic equipment assembly
- Robotic arm and small conveying equipment
- Packaging, printing, and textile machinery
- Tool positioning, parts counting, and stroke limit detection
Notes For Use
- Only sense metal objects; plastic, wood, glass, and non-metal materials cannot be detected.
- Install away from high-power motors, inverters, and high-voltage cables to avoid signal interference.
- Do not exceed the rated sensing distance; keep reasonable gap between the sensor and the detected metal.
- When multiple sensors are installed side by side, maintain a safe spacing to prevent mutual interference.
- Avoid long-term soaking, strong corrosion, and severe mechanical impact.
- Keep the sensing surface clean, remove iron filings and oil stains regularly to ensure sensitivity.
