Highly sensitive magnetic field sensor

Product catalog summary

Field of Application and Technical Specifications

Production Technology: The A-Test LT sensor is used for detecting and tracking magnetism during production, identifying magnetized parts from a distance, and monitoring magnetization processes for duration, intensity, and outcome.
Automation and Metrology: It measures magnetic noise and stray flux, identifies interference sources in the low-frequency range, and monitors demagnetization processes and mechanical movements.
Quality and Safety: The sensor provides contactless detection of parts with residual magnetism, independent monitoring of magnetic sources, and passive registration of vehicles and ferromagnetic materials.

Technical Specifications

Dimensions: 137 x 63 x 31 mm
Power Supply: 24VDC with M12 sensor plug (5 pins)
Measuring Range: DC magnetic field (below Earth's magnetic field) and AC magnetic field (entire low-frequency range)
Sensitivity: Adjustable via potentiometer, with a minimum of ~1.155 mT/V and maximum of ~0.016 mT/V
Resolution: Maximum resolution of ~10 mV (0.16 µT)
Analog Output: Bipolar output with reference voltage for various detection devices, 0...12V at 1kOhm, reference voltage at 6V
Output Type: Configurable NPN 24VDC threshold for detection devices
Settings: Three potentiometers for sensitivity, threshold, and offset, with a solder bridge for 24VDC NPN output configuration

Typical Uses in Automated Production
