INQUIRE NOW
Products Name: AB 56RF-TR-4040 Inductive Proximity Sensor
PRODUCT DESCRIPTION
The Allen-Bradley 56RF-TR-4040 is a rugged, high-sensitivity inductive proximity sensor engineered for non-contact detection of metallic objects in industrial automation. This sensor belongs to the Bulletin 871P family and is designed to provide reliable and accurate sensing even in challenging environments such as high vibration, moisture, and temperature fluctuations. Its compact cylindrical form factor allows for flexible installation in space-constrained areas.

IP69K Protection: Suitable for harsh environments, including high-pressure and high-temperature washdowns.
Reliable Output: Stable PNP NO output ensures consistent performance in control systems.
LED Status Indicator: Simplifies troubleshooting and operational monitoring.
Installation Clearance: Ensure proper clearance around the sensor to avoid interference from adjacent metal objects.
Mounting Orientation: Shielded type reduces sensitivity to surrounding metal, but correct orientation is still important for consistent performance.
Environmental Limits: Avoid use beyond the specified temperature and humidity ranges to prevent performance degradation.
Power Supply Stability: Use a stable, noise-free DC power source to avoid false triggering.
Cable Protection: Protect the sensor cable from sharp edges, abrasion, and excessive bending to maintain signal integrity.
Target Material: Sensing performance may vary depending on the type of metal (e.g., steel vs. aluminum). Always calibrate accordingly.
Material Handling: Used in conveyor systems for detecting metal parts, pallets, or containers.
Automotive Industry: Applied in assembly lines for detecting vehicle components, jigs, and fixtures.
Packaging Systems: Monitors metal caps, foils, and containers in high-speed packaging equipment.
Machine Tooling: Detects tool presence, positioning, and part alignment in CNC and milling machines.
Elevator and Lift Systems: Used for door and position sensing in vertical transport systems.
Food and Beverage: Suitable for washdown environments and detection of metal components in processing lines.
