Amphenol Advanced Sensors A266T Type A266T NTC Thermistor

Introduction

The Amphenol Advanced Sensors A266T is an NTC thermistor designed for dependable temperature measurement across a range of demanding applications. Its stainless steel housing and insulated lead construction make it well suited to environments where a compact, durable temperature-sensing component is needed.

Part Description

The Type A266T is an interchangeable NTC chip thermistor from Amphenol Thermometrics. NTC, or negative temperature coefficient, thermistors decrease in electrical resistance as temperature rises, enabling responsive temperature monitoring and control.

This component is housed in stainless steel for mechanical durability and environmental resistance. It includes TFE-insulated, silver-plated copper leads, supporting reliable electrical connections in equipment exposed to temperature variation. The A266T operates over a temperature range of -40°C to +105°C.
