Option N40 - Increased resistance to industrial cleaning
The 1FT7 motors are available with the option N40 for increased resistance to industrial
cleaning.
You will find the 1FT7 motors that are available with option N40 in Section "Limited validity."
Option N40 improves the resistance of motors to the effects of industrial cleaning agents in
wet areas of a production environment.
Option N40 also applies to the shaft extension of the servomotors.
Additional characteristics of the motor with option N40 as compared with option N16
● Stainless steel shaft
● Sleeve made of stainless steel at the shaft sealing ring
● Lubricating grease in the shaft sealing ring that is compatible with food
● Screws on the outer surface have been surface treated
● Nickel-plated power connector
● Nickel-plated signal connector
● In conjunction with encoder "C," you automatically receive the round connector M17.
● Multi-layer paint finish PS Premium (certified by ECOLAB)
Application environments of the motor
Motors with option N40 are suitable for areas where there are increased demands placed on
the protection properties of the painting system – as well as other exposed motor
components.
The paint system "PS Premium" has been tested with a broad spectrum of industrial
cleaning products with pH values ranging from 1.5 – 13.
The PS Premium paint system is resistant to:
● Acids (e.g. phosphoric acid),
● Alkalis (e.g. active chlorine),
● Disinfectants (e.g. hydrogen peroxide and peracetic acid),
● Salt water,
● Acidic and alkali cleaning agents with the pH value range 1.5. to 13.
Note
The resistance of the paint system "PS Premium" was verified in a material resistance test
by ECOLAB Deutschland GmbH. See Product notification
