Disc Thermal Cut-Outs
ATC Semitec stock a range of snap-action 1/2″ disc-style thermostats from ASAHI which provide very reliable, thermal protection for domestic appliances and electronic circuits.
The typical application of a thermal cut-out is to keep a safe temperature below a particular threshold during abnormal operating conditions. Also known as a thermal limiter or thermal switch, they normally open at high temperatures during a fault condition and then reset when the product temperature falls to a safe, predefined level.

RTD Temperature Sensor Assemblies
YAGEO Nexensos not only supply a wide range of platinum RTD elements but also temperature sensor assemblies in various formats. Of all the numerous sensor designs, two of the most interesting are as follows;
EC3032 temperature sensors are high integrity, encapsulated RTD sensors primarily designed for use in e-vehicle e-motor applications. Their small size and IP68 insulation rating makes them ideal for use in the e-motor stator windings and they are also impervious to varnish ingress and other fluids such as oil or grease. Using a Pt1000B element as standard, the 410mm PTFE long leads make this a very versatile sensor that can be used from -50°C to +200°C.
Our PCB RTD temperature sensors are basically chip RTD elements pre-soldered onto printed circuit boards (PCBs) originally designed for use in domestic calorimeters. The PCB has a meandering, zigzag circuit path to help minimise heat loss from the RTD to improve temperature measurement accuracy. These RTD PCB sensors are sometimes preferred to NTC versions, as their inherent long-term stability is extremely important when accurately measuring and apportioning consumer energy consumption in district heating systems.
Thin Film Platinum RTD Sensor Elements
YAGEO Nexensos’ wired Pt-RTD sensor elements are designed for either PCB mounting or for use in temperature sensor assemblies. Our wide range of sensors, available from UK stock, ensures that there is a suitable product for your application.
Our M-series RTD sensor elements are the best choice for general applications, being suitable for use from -70°C to +500°C. Pt100, Pt500 and Pt1000 options are available on chips as small as 2mm x 2mm square with even smaller formats now offered.
PEPI Thermal Protectors
PEPI thermal protectors from ATC Semitec offer superior and reliable over-temperature protection from 5°C to 200°C with current ratings up to 15A/250VAC. Their neat design small package sizes help to protect circuits in the tightest of spaces.
PEPI bi-metal protectors can be supplied as automatic-reset limiters, self-hold cut-outs or even one-shot fuses offering different levels of safety depending on what the application or approval standard requires. PEPI C and V thermostats are auto-resetting whereas the low-profile PEPI JS offers self-hold, non-resetting protection for both 240VAC and 120VAC.
PEPI J-2 and PEPI H bimetal fuses offer the ultimate in reliable thermal protection, with some ceramic versions offering over-temperature protection up to 280°C.
