Product Description

The SICK UFN3-70P415 (Part No. 6049679) is a high-performance ultrasonic fork sensor designed specifically for the challenging requirements of the labeling and packaging industries. Unlike standard optical sensors, the UFN3 utilizes ultrasonic technology to detect transitions between labels and carrier materials, making it remarkably effective at identifying transparent, metallic, and high-gloss labels on various substrates.

The sensor features a compact, rugged aluminum housing with a 3mm fork width and 69mm fork depth, ensuring it fits easily into tight machine spaces while providing high mechanical stability. It operates on a 10V to 30V DC supply and offers a fast response time of 250 µs, allowing for high-speed production without sacrificing accuracy. Users can easily configure the device using the onboard plus/minus teach-in buttons for sensitivity and switching functions, or via an external cable for dynamic teach-in. With an IP65 enclosure rating and a wide operating temperature range of +5°C to +55°C, the UFN3-70P415 provides reliable, maintenance-free operation in demanding industrial environments.

 

Key Performance Features

  • Ultrasonic Detection: Reliable detection of transparent, opaque, or printed labels regardless of color or surface finish.
  • High Switching Frequency: 1.5 kHz switching frequency for precise positioning at high web speeds.
  • Fast Response Time: 250 µs response time ensures high repeat accuracy.
  • Flexible Setup: Simple 2-point teach-in process via manual buttons or remote cable.
  • Durable Construction: Rugged IP65-rated aluminum housing resistant to vibration and industrial wear.
  • Adjustable Logic: Selectable light/dark switching to suit specific application logic.
  • Key Lock Function: Ability to lock the buttons to prevent accidental or unauthorized setting changes.

 

Ideal Applications

  • Labeling Machines: Detecting transparent “clear-on-clear” labels on bottles and packaging.
  • Packaging Industry: Monitoring label presence and web breaks on high-speed production lines.
  • Printing Industry: Controlling the feed and alignment of foil and paper materials.
  • Logistics & Sorting: High-precision edge detection for various material types on conveyor systems.
  • Splice Detection: Identifying web splices and joints in continuous material rolls.
