KTY81/220,112

The KTY81/220,112 is a semiconductor temperature sensor belonging to the KTY81 series, a family of silicon-based linear temperature sensors widely used in industrial measurement and control applications. This component is designed to provide accurate, reliable temperature monitoring across a broad range of operating conditions, making it suitable for demanding environments where precise thermal data is critical. Temperature sensors from the KTY81 family are known for their linear output characteristics, which simplify signal conditioning and integration into measurement systems. The sensor functions by exploiting the temperature-dependent properties of silicon, delivering a measurable output that correlates directly to ambient or process temperature. This makes the KTY81 series particularly attractive for applications requiring straightforward analog signal processing without complex calibration or correction algorithms. The KTY81/220,112 designation indicates this particular variant within the KTY81 family, with the specific numerical suffix reflecting particular performance or packaging characteristics relevant to its intended application. These sensors are commonly used in industrial control systems, HVAC equipment, automotive thermal management, medical instrumentation, and consumer appliance temperature monitoring. The linear output and stable performance characteristics make them especially valuable in closed-loop temperature control systems where feedback accuracy directly impacts system efficiency and product quality. One key advantage of specifying the KTY81 series is the combination of simplicity and reliability. Unlike thermocouples, these silicon sensors require no reference junction compensation. Compared to resistive temperature detectors (RTDs), they typically offer faster response times and simpler interface requirements. The integrated semiconductor construction also provides excellent stability over time, reducing drift concerns in long-term applications. Engineers select this specific part number when system requirements call for the particular performance envelope, package configuration, or electrical characteristics associated with the 220,112 variant. The KTY81 family is particularly popular in European industrial applications and OEM equipment, where standardization on this sensor type simplifies procurement, spare parts management, and technician training across product lines. The robust construction of silicon temperature sensors makes them suitable for industrial environments with varying humidity, vibration, and electromagnetic interference. Their relatively compact form factor allows integration into space-constrained applications while maintaining measurement accuracy and long-term reliability. For engineers evaluating temperature sensing solutions, the KTY81 series represents a mature, well-proven technology offering excellent value for applications requiring dependable thermal monitoring without unnecessary complexity or cost overhead.
