Applications
Limit temperature sensor
Features
Sensor with epoxy resin coating
Tinned leads
Metal tag for easy mounting
Characteristics for sensing temperatures
T
sense
= 90 to 120
°C
conform with DIN 44081
Metal tag permits good thermal coupling and
thus short response time
Marking type D1052: Type, manufacturer's
logo, T

and date code
YYWW
Marking type D901: Three digits stamped on
to identify T
sense
RoHS-compatible
Delivery mode
Type D1052: Cardboard strips with hot-melt
adhesive tape in cardboard box (800 pcs.)
Type D901: Cardboard strips with manila
paper strips in cardboard box (500 pcs.)
