SKTY Sensors – Linear PTC Elements

The SKTY series linear PTC sensing elements offer direct 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 – they are sometimes known as PTC1000 and PTC2000 sensors.

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