Product description
SICK PLG3-210F431 (1028548) – Automation Light Grid, 210 mm Detection Height
The SICK PLG3-210F431 is a compact retro-reflective automation light grid from the PLG series, designed for reliable object detection and presence monitoring in standard industrial automation environments. With 8 parallel beams, 210 mm detection height, and plug-and-play installation, it delivers straightforward integration into a wide range of machine and conveyor applications.
Key Features of the SICK PLG3-210F431 Light Grid
- Retro-reflective sensor principle — single-unit installation with integrated backside reflector
- 8 beams with 30 mm beam separation across 210 mm detection height
- Minimum detectable object (MDO): 35 mm
- PNP switching output — dark switching (output active when at least one beam is interrupted)
- Configurable output mode and job LED behaviour via DIP switches — no software required
- Plug-and-play M12 connector for fast installation
- Compatible with standard mounting profiles (ITEM, Bosch, round profiles) using slot nuts
- Short-circuit protected output, reverse polarity protection, interference pulse suppression
- Compact aluminum housing with PMMA front screen
- LED indicators: power (green) and beam status (yellow) + configurable job LED (green)
Industrial Applications
- Conveyor systems: Detects the presence or absence of objects passing through the detection zone
- Packaging lines: Monitors product flow and identifies gaps or missing items on the line
- Assembly stations: Verifies part presence before initiating assembly or machining operations
- Sorting and feeding systems: Detects objects at entry or exit points of sorting equipment
- Machine access monitoring: Detects intrusion of tools or parts into machine zones (non-safety application)
