Sensata Airpax 67F070 Thermal Switch, Normally Open, 70°C

The Sensata Airpax 67F070 Thermal Switch is a normally open thermostat with a factory pre-set 70°C switching temperature, designed for precise temperature sensing and switching in electronic applications.

Overview

The Airpax 67F070 is a subminiature bimetal disc thermostat engineered for precision and reliability. It functions as a fan close on rise switch and features a positive snap action with a single pole/single throw design. This arrangement provides accurate sensing and switching within a compact device, with fast response times and excellent repeatability for consistent performance.

Key Features

• Switching temperature factory pre-set to 70°C, with a reset temperature of 50°C
• Non-adjustable in the field for stable and dependable operation
• Gold-plated contacts for reliable switching and longevity
• Operating temperature range of -40 to 130°C
• Contact rating of 1A at 120V AC or 1A at 48V DC
• Up to 20,000 life cycles at maximum standard amperage, and up to 100,000 life cycles at maximum gold contact amperage
• Member of the Airpax 6700 series
• Dimensions: 2.2 (width) x 0.2 (depth) x 3.3 (height)
• Weight: 2 g

Mounting and Thermal Conductivity

Thermal conductivity is primarily achieved through the terminals and the included nickel-plated copper mounting bracket, making the unit ideal for both surface mount and ambient air sensing applications. A laminated plastic mounting bracket is also available as an alternative, offering enhanced dielectric strength and VDE approval.

Applications

The thermostat is suited to crowded printed circuit (PC) boards and to surface and air sensing on PC boards and heat sinks. Typical applications include:

• Activating an indicator light to signal a temperature event
• Sounding an audible alarm for overtemperature warnings
• Switching a control circuit to send a message to a display screen
• Safely shutting down a system or subsystem to prevent damage from overheating

The Sensata Airpax 67F070 Thermal Switch, weighing 2 g, is a compact solution for electronic protection and control tasks requiring a 70°C normally open switching point.
