About Us

ATC Semitec offer an extensive range of innovative thermal products which are used across a wide range of products and market sectors. Using a combination of our technical expertise and comprehensive product ranges from our world leading manufacturers, we work with you to find the optimal solution to your temperature sensor and thermal safety requirements.

Our ranges include – Semitec’s NTC thermistors and thermistor sensors provide high accuracy temperature sensing and control for electronic and programmable thermostats. Platinum RTD sensor elements from Heraeus provide accurate and reliable temperature control for industrial and automotive applications, offering  a constant linearity and precision at very high temperatures. PEPI thermal cut-outs and Asahi thermostats offer cost-effective temperature control or over temperature protection whereas Matsuo’s long-life precision thermostats bridge the gap between electronic temperature controllers and simple mechanical thermostats. Bimetallic thermal protectors and thermostats from SEKI are ideal for high temperature control in home and industrial appliances. Reliable circuit protection is provided by NEC Sefuse thermal fuses, TKS PTC Thermistors and Semifuse PTC fuses. Constant current is supplied via Semitec CRD current limiting diodes and current surges controlled by SCK inrush current limiters. And within the HVAC market, Campini adjustable thermostats provide accurate room temperature control and TKS humidity sensors can help provide a comfortable environment.
