ISUB250-F77K12
F77 0.25M Square Miniature Ultrasonic Proximity Switch
Miniature Design, 250mm Sensing Range, IP67 Waterproof, Transparent Object Detection, High Switching Frequency, Small Blind Zone, NPN/PNP Output, Background Suppression, PCB Detection, Liquid Level Monitoring
The F77 Ultrasonic Proximity Switch is a high-performance, miniature sensor designed for the rigorous demands of modern industrial automation. Engineered with a compact square housing, this sensor delivers exceptional reliability in detecting clear, liquid, or solid targets where standard optical sensors fail. With a sensing range of up to 250mm and an ultra-small 20mm blind zone, the F77 is the ideal solution for restricted spaces in packaging, electronics assembly, and material handling systems.
Why Choose Ultrasonic Technology?
Unlike photoelectric sensors that struggle with color variations or transparency, our ultrasonic proximity sensors utilize sound waves for detection. This ensures:
Color Independence: Reliably detects black, white, or shiny objects.
Transparency Detection: Perfect for clear glass bottles, plastic films, and liquid levels.
Dust Immunity: Resistant to industrial dust and dirt that often fouls optical lenses.
Key Features & Advantages
Miniature Footprint: The ultra-compact design fits effortlessly into tight machine geometries, replacing larger, bulkier sensors.
Precise Background Suppression: Excellent acoustic focus minimizes false triggers from background machinery or guide rails.
Simple "Teach-In" Setup: Features an intuitive learning mode (A1 point) for rapid commissioning without complex programming software.
Industrial Ruggedness: Built with a durable plastic composite housing and rated IP67, ensuring full protection against water ingress and dust in washdown environments.
High-Speed Response: Optimized switching frequency for fast-moving conveyor lines and rapid object counting.
Common Applications
The F77 ultrasonic proximity switch is versatile across multiple sectors:
Packaging Industry: Detecting transparent bottles, counting clear films, and monitoring roll diameters.
Electronics (PCB): Precise detection of printed circuit boards on mini-conveyors (dark/shiny surfaces).
Liquid Level Control: Non-contact level monitoring in small tanks or vials.
Robotics: End-of-arm tooling (EOAT) for grip verification and obstacle avoidance.
