SIS SS EN 50 037-1989 Low-voltage switchgear and controlgear for industrial use — Inductive proximity switches — Form C, for alternating current, 2 terminals
This standard specifies only inductive proximity switches for alternating current, in rectangular form, with square cross-section, with two terminals, for rated voltages between 24 V and 240 V (r.m.s.).
These proximity switches are not embeddable in metal.
Two types are included:
With front sensing face: C41?1
Not embeddable in metal: C41?2
