PEPI Thermal Cut-Outs
PEPI (Portage Electric Products Inc) thermal cutouts provide over-temperature control and thermal protection from 5°C to 200°C. PEPI protectors can be calibrated down to a ±5K tolerance and with a wide temperature differential, they offer a compact solution to solve over-temperature problems. The latest PEPI FCP and PEPI ST01 thermal protectors offer combined thermal/current overload protection and can readily switch up to 8A/250VAC or 12A/24VDC.
One of PEPI’s neatest designs is an integral “self-hold” thermal and current sensitive cut-out, the model JS. The PEPI JS protector latches open after tripping and is then reset remotely, thus offering the same benefit as fitting a manual-reset cut-out but without the disadvantage of having to access it.

NTC Thermistors
By definition – NTC thermistors are highly sensitive thermal resistors that respond very quickly to rapid changes in temperature- the word thermistor itself is a contraction of “thermal” and “resistor”.
NTC thermistors are so-called because of the resistance of an NTC decreases with an increasing temperature and their R-T (Resistance – Temperature) is very accurately defined. The R-T accuracy combined with the fast rate of change (compared to RTDs and thermocouples) makes them ideal to incorporate in electronics control circuitry
Precision NTC Thermistors
Our range of high precision NTC thermistors enable engineers to accurately control operating temperatures which is critical in many product applications within the automotive, home automation and medical device industries.
Precision thermistors are highly accurate with 0.5% resistance tolerances (or better) offering long term stability and control; their RT curve interchangeability eliminates the need for individual circuit calibration. Available with ±0.2°C (0-70°C) accuracy or better, they can operate up to 150°C and so are also suitable for use in automotive applications. With a wide range of R25 resistance values, B values and format types, please call us about specific requirements.
Fast Response Temp Probes
Some temperature control applications, such as domestic showers and instant water heaters, require a very fast thermal response of 1 second or less. This is to maximise the thermal efficiency of the device and avoid potential scalding of the user.
In response to this, ATC Semitec stock a number of very fast-response temperature probes where the NTC thermistor is situated in the very tip of the sensor. This reduces the thermal path to the thermistor and thus minimises the thermal response time. Response times can be further accelerated by using our thin wall tip or exposed NTC sensor.
Our standard sensor assembly packages include: screw threaded bosses, bayonet fittings and push-fit/clip-in designs – all of which are available with flying leads and/or industry standard connector options.
