Product Overview
The Airpax 6600 series is a RoHS compliant, positive snap action, single pole / single throw, sub-miniature bimetallic thermostat. It offers accurate and reliable sensing and switching in a single device, dimensionally conforming to the 8-pin DIP international product package standard. Ideal for printed circuit boards, its compact size conserves space and is compatible with auto-insertion equipment. The device is sealed for wave soldering and board washing, providing fast, positive response with excellent repeatability. It supports switch capabilities up to 1A for 48 VDC or 120 VAC, and low-level switching down to 0.020A at 5 VDC for 100,000 cycles. Temperature is factory pre-set and non-adjustable. Applications include computers, peripherals, aircraft, automotive, and test equipment, for functions like indicator lights, alarms, or system shutdowns. Independent customer testing may be necessary to ensure correct calibration in specific applications.
