Diffuse sensor HT46CI/2N-M12 Leuze Vietnam
Leuze HT46CI-2N-M12 – High-Performance Diffuse Sensor with Background Suppression
Leuze, a trusted leader in industrial sensor technology, presents the HT46CI-2N-M12 — a powerful diffuse (proximity) sensor with background suppression that delivers reliable detection even in challenging environments and supports long-range applications up to 3 meters.
Key Features
-
Diffuse detection with background suppression
The sensor reliably detects objects while suppressing the background — ideal when the background is complex, reflective, or variable. -
Extended detection range
-
White (90% reflectivity): 0.005 to 3 m
-
Gray (18%): 0.02 to 2 m
-
Black (6%): 0.05 to 1.5 m
-
-
Infrared LED light source
Uses a pulsed IR LED (~860 nm) to ensure stable performance. -
Fast switching & response
