Metal-glass headers for IR, XRF and other types of detectors.
The basic material of TO-66 type header is usually Kovar or nickel and gold coated steel. Ferrotec-RMT manufactures thermoelectric assemblies for TO-66 headers with 6 or 9 pins. The header pins can be standard (cylindrical shape) or with flattened ends or nail shape to simplify wire bonding.
Below are examples of solutions with thermoelectric coolers installed on TO-66 headers. The full list of possible solutions is larger. The TO-66 header is suitable for any thermoelectric cooler with hot side dimensions up to 8x8 mm2.
