SKTY Sensors & Linear PTC Elements

ATC Semitec’s SKTY series linear PTC sensing elements offer replacements for the once common KTY temperature 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.

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


  • Operating temperature range: -50°C to +150°C
  • Steeper linear slope improves accuracy
  • R25 tolerance ±1% at 25°C
  • Excellent long-term stability
  • Linear Output


  • Air conditioning systems
  • Industrial electronics
  • Automotive electronics
