Overview
The Tri-Tronics UCF-AT1 fiber optic sensor is a self-contained photoelectric control designed for reliable object detection in industrial environments. This on/off delay timer sensor uses infrared LED technology and fiber optic light guides to deliver sensing capability to difficult-to-reach positions where traditional sensors cannot mount directly.
Key Features
- Fiber Optic Configuration: Decoupled sensing head and control module for flexible installation in tight spaces
- Adjustable Timer: Delay range 0.1 to 15 seconds for on or off output switching
- Fast Response: 7 millisecond response speed ensures precise object detection
- Extended Sensing Range: Up to 12 feet opposed range with optional lens (2 feet without lens)
- Compact Design: Lightweight unit (0.60 lbs) suitable for OEM and retrofit applications
Technical Specifications
- Sensing Type: Fiber Optic, Infrared LED
- Response Speed: 7 milliseconds
- Opposed Range (with lens): 12 feet
- Opposed Range (without lens): 2 feet
- Proximity Range (with lens): 4 inches
- Proximity Range (without lens): 2.5 inches
- Timer Adjustment: 0.1 to 15 seconds
- Output Type: On/Off relay or triac (model dependent)
- Weight: 0.60 pounds
- Mounting: DIN rail or bracket mounting compatible
Typical Applications
The Tri-Tronics UCF-AT1 is ideal for:
- Bottling and filling line control with optical sensing to confined areas
- Packaging equipment synchronization using fiber-optic light guides
- Assembly automation where sensor heads must mount away from the control logic
- Material handling and conveyors requiring precise timing and detection
- OEM equipment retrofit where space or environmental constraints limit sensor placement
