Panasonic HG-C laser sensor - 10 µm resolution

Panasonic, a world leader in Industrial Automation Products, is pleased to announce the NEW HG-C Series Laser Distance Sensor.
With a compact size of just W20 x H44 x D25 mm this sensor provides high-end performance in a small, lightweight package. Three measurement ranges (100mm±35, 50mm±15, and 30mm±5) are available with a measurement resolution ranging from 10 μm to 70 μm depending on the model selected. The built-in display assist in setup and operation, and I/O options include a 0-5V analog output alongside either one NPN or PNP transistor output as well as an external input.
As compact as a photoelectric sensor, the CMOS laser sensor allows to display actual measured distance as accurately as a displacement sensor.
  • Accurate > Linearity: +/-0.1% F.S.
  • Compact & light weight > W20mm x H44mm x D25mm
  • Precise level detection > Repeatability: 10μm
