ATC Semitec now stocks motor protection PTCs to complement its range of re-settable thermal cut-outs.

The new SPMP PTCs are available with trip temperatures from 60 to 190°C and comply with the DIN 44081 industry standard.

The small PTC bead is protected with epoxy resin and a shrink sleeve.

The sensing head is just 4mm max.

diameter and gives a thermal response of less than 5s. The standard version has 200mm long 26AWG PTFE leads; with longer leads, triplet versions (to DIN 44082) and various mounting options available.

Although designed for electric motor protection, the sensors offer a neat solution to many electrical and electronic circuits that require a simple step-function response to an over-temperature condition.
