Product Overview

The 66F085 is a 8-pin DIP Subminiature Bimetal Disc Thermostat with gold-plated fan (close on rise) (SPST) positive snap action contacts and PPS (polyphenylene sulfide) UL94V-O rated base. It is ideal for surface and air sensing on PC boards. It provides accurate and reliable sensing and switching in a single device. It features fast, positive response with excellent repeatability. It has a switch capability of up to 1A and achieves low-level switching down for 100000 cycles. The temperature is pre-set at the factory and is non-adjustable in the field. The 6600 thermostat is temperature tested in a computer controlled automated test equipment air-oven. Due to the ideal conditions under which it is tested, independent customer testing may be necessary to ensure that the correct calibration is utilized in the application.
