Overview
The Balluff BGL-220A-002-S49 is a self-contained photoelectric fork sensor designed for precise slot and opening detection in machinery and conveyor systems. Unlike traditional through-beam setups requiring separate transmitter and receiver units with fiber optics, the BGL-220A-002-S49 integrates both optical elements in a single U-shaped housing, reducing wiring complexity and setup time. With a 220mm fork opening, this sensor handles applications where parts, sheets, or labels need reliable sensing at high speeds.
Key Features
- Through-beam operation — Detects objects passing through the fork opening with 0.6mm sensing resolution
- Divergent red LED emitter — 640nm wavelength, visible and reliable in production environments
- PNP output logic — NO/NC selectable operation via 270° potentiometer
- Light/dark switching selectable — Adapt to light-on or dark-on operation modes
- IP67 sealed — Withstands washdown and harsh factory conditions
- Fast response time — 0.33 ms switching speed, 1.5 kHz repeat frequency
