The VC5E400 is a Hall-effect vane sensor from Honeywell Sensing and Productivity Solutions. This sensor detects the presence or absence of a ferrous object (vane) passing through a gap in the sensor. It's a robust and reliable solution for position and speed sensing in a variety of industrial and automotive applications.

Applications

• Speed sensing in motors and gearboxes
• Position sensing in valves and actuators
• Flow rate sensing in pumps and meters
• Tachometers
• Robotics and automation equipment

Features

• Digital output
• Unipolar Hall-effect sensing
• High sensitivity
• Wide operating temperature range
• Robust design
• Integrated pull-up resistor (in some versions)

Benefits

• Provides a clean and reliable digital signal indicating the presence or absence of a vane.
• Offers simple and cost-effective sensing solution compared to other technologies.
• Detects small changes in the magnetic field, enabling precise position and speed measurements.
• Operates reliably in harsh environments.

Technical Specifications

The VC5E400 typically operates with a supply voltage of 4.5V to 24V. The output is a digital signal (high or low) depending on the presence or absence of the vane. The switching frequency is typically in the kHz range. The operating temperature range usually extends from -40°C to +150°C. The sensor has a built-in hysteresis to prevent chattering. The housing is designed for easy mounting. Refer to the Honeywell datasheet for the exact specifications, including the supply voltage range, output voltage levels, switching frequency, sensitivity, and temperature characteristics. Details regarding the optimum vane dimensions and air gap are critical for proper operation and are found in the datasheet.

Hall-effect vane sensors like the VC5E400 are non-contact sensors, which means they do not wear out over time, offering long-term reliability and durability.
