DR46 Compensated

Features

A one-channel compensated thin-film thermopile in a TO-8 package. The active area and compensating element area are 4mm x 0.6mm each. Offers high output with very good signal-to-noise ratio. Internal aperture minimizes channel-to-channel crosstalk increasing sensitivity.

Applications

Non-contact temperature measurement, fire detection / suppression.

Benefit

High output, low noise compensated rectangular shaped active area in a TO-8 package.

Options

  • See Standard Windows and Filters (PDF) for list of optical filter options.
  • See Thermopile Configuration Table for more options.
