Sensata Airpax 6700 Series Thermal Switch, NC, 80°C, TO-220

The Sensata Airpax 6700 Series Thermal Switch is a normally closed (NC) thermal switch with an 80°C switching temperature, designed for accurate thermal sensing and switching in demanding thermal management applications.

Overview

The Airpax 6700 Series is a high-performance, positive snap-action bimetallic thermostat. Its sub-miniature, single-pole single-throw design provides a fast, positive response with excellent repeatability, supporting consistent operation across its lifecycle.

Electrical Performance

• Load rating: up to 0.5A at 48VDC
• Low-level switching: 0.001A–0.020A at 5VDC
• Cycle life: up to 100,000 cycles

The switch handles both power and signal circuits, offering versatile switching capability across these loads.

Design and Construction

The switch is housed in a TO-220 / Y-220 international electronic package and is suited to surface and air sensing on crowded printed circuit boards (PCBs) and heat sinks. Thermal conductivity is managed through its terminals and mounting bracket. It features gold-plated contacts for enhanced reliability and longevity, supporting up to 100,000 life cycles at maximum gold contact amperage.

Two mounting bracket options are available: a standard nickel-plated copper bracket, or a high-pressure laminated plastic 'P' bracket which carries VDE approval for added safety compliance in relevant applications.

Applications

The primary function is thermal protection and management. Typical uses include activating indicator lights, sounding audible alarms, switching control circuits to send messages to displays, or initiating a system shutdown.
