  • ATC Semitec IP68 Waterproof Platinum Sensors

    For applications where a high IP rating is required, our ATC Semitec IP68 Pt100 (or Pt500/Pt1000) sensors ensure that water ingress will not be a problem.

    Moulded in TPE, the sensing portion is 5mm dia. x 20mm long and is available in single or double-insulated formats. The double-insulated versions offer a dielectric strength up to 3.75kV.

    • Suitable for continuous use from -50/+110°C, they can also be used to 125°C for periods of up to 3000 hours.
    • Utilising one of our platinum RTD elements, we supply Pt100, Pt500 or Pt1000 class B sensors with an accuracy of ±0.15K.
    • 4 wire Class A platinum sensors are available offering an even higher degree of accuracy.
  • ATC Semitec SKTY Sensors & Linear PTC Elements

    ATC Semitec’s SKTY series linear PTC sensing elements from ATC Semitec offer neat replacements for the once common KTY sensors. The SKTY sensor elements are mounted on a small 3mm x 6mm p.c.b. and are available with R25 values of 1kohm and 2kohm with ±1% tolerances.

     

    • Operating temperature range -50°C/+150°C
    • Fast response
    • Steeper linear slopes of higher accuracy ±1% at 25°C
    • Excellent long-term stability
    • Linear Output
    • SMD mounted on p.c.b.

     

    SKTYs can also be supplied as IP68 rated moulded sensors (see above) with single or double-insulated leads. Other custom probe formats are also available as required.

  • PTCs as Resettable Current Fuses

    Ceramic PTC thermistors are often used as re-settable current fuses as they offer several benefits over conventional fuses. Over-voltage or over-current conditions cause the PTC thermistor to “switch” from a low resistance to a high resistance state, effectively limiting (switching off) the through current. The PTC acts as a current fuse and protects the electronic circuit, electrical appliance or series load.

    Often simpler to incorporate in a circuit than a current fuse, PTC fuses also don’t need replacing and thus help to minimise service calls when nuisance tripping is caused by various transient surges.
