Product Description
Miniature inductive proximity
sensor available as 4 and
5 x 5 mm types. Output con-
figuration for NPN/PNP with
both NO and NC types as
standard. Housing materials
are stainless steel for 4 and
aluminium for the 5 x 5 mm
type. Cabled models utilise 2
meters of PUR cable and
plug versions features a
bright ring LED.
