Sampling now: TO-220 thermostats for robust surface and air sensing

Written by: Charcroft Electronics Ltd | Published:

Accurate and reliable sensing and switching are combined in a single TO-220/Y-220 package with Airpax™ sub-miniature bi-metal disc thermostats. Designed for surface and air sensing on PC boards and heat-sinks, the 67F/L series offer long-term reliability up to 100,000 life-cycles. Request a sample now from Charcroft Electronics.

The Airpax™ 6700 series of positive snap-action, single-pole / single-throw, sub-miniature bimetallic thermostats provides accurate and reliable sensing and switching in a single device.

Housed in a standard TO220/Y220 package, the 6700 series thermostats are compatible with high-speed automatic placement and soldering onto PC boards. This eliminates the manual placement and termination required by most power-supply thermostats.

The 6700 series provides fast, positive response with excellent repeatability. The switch capability of up to 0.5A for 48 VDC achieves low-level switching down to 0.001A to 0.020A at 5 VDC for 100,000 cycles. The temperature is pre-set at the factory and is non-adjustable in the field.

Thermal conductivity through the terminals and the mounting bracket makes these thermostats suitable for surface-mount and ambient air sensing. The standard device offers a nickel-plated copper mounting bracket whilst a laminated plastic mounting bracket can be used for increased dielectric strength and VDE approval.

The Airpax™ 6700 series are typically used for thermal management on power supplies, particularly on high-density PC boards in aircraft, automotive, medical devices and test equipment. Applications for the 6700 series include turning on an indicator light, sounding an audible alarm, switching on a control circuit to send a message to a display screen or switching a circuit to shut-down a system.
