Note: For positive logic Remote On/Off add suffix “P” or negative logic remote On/Off suffix “N”

For Remote Sense add suffix “S” & for right angled mounting pins suffix “R”.

If Sense or Right Angled pins not required just leave blank. i.e. PMQ7250-1P would be standard unit with

positive logic Remote On/Off and no Sense terminal and straight mounting pins. PMQ7250-1PSR would be unit

with positive logic Remote On/Off, Sense & Right Angled Pins.
