Description
Overview
The IFM cr0020 is a robust capacitive proximity sensor designed for non-contact detection of solids and liquids in mobile and industrial applications. With an IP69K enclosure and a PNP NO output, this sensor ensures reliable performance even in extreme environments involving mud, oil, or high-pressure washdowns.
Technical Features:
Capacitive sensing range: Adjustable from 1 to 15 mm
Wide voltage range (10–30 V DC) for flexible integration
IO-Link compatibility for advanced diagnostics and parameterization
Integrated LED for signal status feedback
Performance Advantages:
Accurate and consistent object detection regardless of material type
Resistant to moisture, corrosion, and high-pressure cleaning
Extended service life with minimal recalibration needs
Application Use Cases:
Heavy trucks and vehicle maintenance – sensor for fluid level detection and presence sensing
Construction machinery – detect hydraulic fluid, material levels in tanks
Food-grade and pharmaceutical equipment – washdown-compatible sensor for sanitary environments
Manufacturing automation systems – proximity sensing for conveyor and filling stations
Comparison to Alternatives:
Unlike conventional inductive sensors, the cr0020 detects both metallic and non-metallic materials
Offers superior ingress protection (IP69K vs. IP67 in standard models)
Lower total cost of ownership due to longer maintenance intervals
