DSE-26B Digital Line Guide Sensor Overview

The Fife DSE-26B digital line guide sensor delivers accurate detection for both low-contrast printed lines and transparent film edges, even in demanding production environments. With advanced RGB LED illumination and robust IP67 construction, the DSE-26B provides reliable guiding performance for years of operation.

The DSE-26B builds on the trusted SE-26B platform by introducing next-generation RGB optics, stronger IP67-rated protection, and expanded integration options. For customers maintaining existing installations, the SE-26B remains fully supported and available. For those planning new projects or system upgrades, the DSE-26B provides added performance and flexibility.

Engineered for Consistent Line & Edge Tracking

The DSE-26B combines advanced optical sensing with durable construction to ensure accurate guiding across a range of materials and production speeds. Some key engineering features include:

High-resolution sensing for faint or narrow printed lines
Transparent film edge detection with minimal background contrast requirements
Electrostatic immunity for consistent readings in challenging environments
Adjustable mounting bracket for precise alignment and positioning

Key Benefits

Low-contrast champion — reads faint lines reliably on varied substrates.
Transparent film ready — detects film edges even when background contrast is poor.
Production-tough — IP67 protection; insensitive to electrostatic discharge.
Long service life — LED illumination designed for ~100,000 hours.
Lightweight & compact — ~100 g sensor with straightforward bracket mounting.

Common Applications

Printed line following (registration, width control)
Edge/centerline guiding on film, foil, paper, laminates
High-speed packaging and converting

System Compatibility

The DSE-26B integrates easily with existing Fife controls and components, making it a versatile choice for both new and retrofit projects:

Controllers/Interfaces: integrates with Fife controls via 0–20 mA or RS-485 communications
Recommended Pairing: Fife SmartDrive Actuator for closed-loop actuation + D-MAXE Web Guiding Controller for seamless operation
Optional setup and visualization through the DP-20 Plus Operator Interface
