📝Description

This TRS-W thermal reed sensor offers precise temperature sensing capabilities with an accuracy of within 2-3°C. These sensors are designed to cater to a diverse array of applications where temperature control and monitoring are critical.

One of the key features of thermal reed sensors is their low level load switching capability, determined by the reed switch employed, which can handle up to 10W of electrical load. This capacity ensures reliable operation in applications requiring electrical switching based on temperature thresholds.

Designed as direct replacements for traditional bimetallic strips, thermal reed sensors are specifically available in a Normally Closed (NC), Form B type contact configuration. This means that the switch remains closed under normal conditions but opens when the preset temperature threshold is reached. This functionality is essential in applications where precise temperature control and safety are paramount, ensuring prompt response to temperature changes to prevent equipment damage or ensure operational safety.

The construction of thermal reed sensors incorporates robust materials that ensure durability and reliability in various environmental conditions. This durability is crucial for maintaining consistent performance over extended periods, making thermal reed sensors suitable for demanding industrial and commercial environments.

Applications for thermal reed sensors span industries such as power supplies, mobile electronics, medical equipment, and automotive applications, among others. Their ability to provide accurate temperature monitoring and responsive switching enhances operational efficiency and equipment longevity.
