1/2" Disc Thermostats

For an ultra-reliable, waterproof temperature sensor with IP67 or IP68 integrity, then look no further than our range of TPE-encapsulated sensors.  These over-moulded NTC Thermistor probes use the same TPE moulding material as the integral lead-wire’s insulation.  By using double-insulated or single-insulated TPE cable, a true waterproof seal is created by the fusion of the two insulating materials making the sensors suitable for direct immersion in the media being measured.  This makes them ideal for refrigeration, air-conditioning, underfloor heating and heat pumps, solar and other green energy solutions.

Our IP67 and IP68 waterproof sensors can be fitted with any NTC Thermistor from our AP-2, AT-2, ATCD, NT-4 or SP series ranges.  From this very wide range of R25 and B values, we can match or fine-tune the sensor specification to meet your application requirements.  Also Pt100, Pt500 or Pt1000 RTD elements are now available in IP67 or IP68 versions. ATC Semitec now stock the YAGEO NEXENSOS EC3032 an IP68 rated RTD temperature sensor

Cable lengths can be supplied from 100 mm up to 10 metres long so that you have a single uninterrupted sensor cable helping to ensure product integrity.  Metal tips or stainless-steel housings can be added to help increase their physical robustness where an abrasive sensing environment could be encountered.  For even harsher environments, shielded cable options and armoured cabling is also available.

ATC Semitec’s range of glass NTC thermistors includes NT-4 radial glass beads, ATCD series DO-35 diode style NTCs and FT thin film thermistors, suitable for accurate high temperature control up to 350°C.

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.
