Types that can be ordered (

The inductive proximity switches used are equipped with reverse
polarity protection and are short-circuit-proof.
Make sure that you handle the proximity switches properly:
• Do not pull on the cable.
• Do not allow the sensor to dangle from the cable.
• Do not overtighten the mounting screw or mounting clip.
• Please adhere to a permitted bend radius of the cable (
☞
catalog).
• Avoid contact of the proximity switches with hard objects and
with chemicals, in particular nitric acid, chromic acid and
sulphuric acid.
The inductive proximity switches are electronic components,
which can react sensitively to high-frequency interference or
electromagnetic fields.
• Check to make sure that the cable is fastened and installed
correctly. Provide for sufficient clearance to sources of high-
frequency interference and their supply cables.
• Parallel switching of several sensor outputs of the same type
(npn, pnp) is permissible, but does not increase the permissible
load current.
• Note that the leakage current of the individual sensors (approx.
2 mA) is cumulative.
Pressurize connection A with compressed air.
Plug in the proximity switch 1 into the bracket of the contact plate
until the distance between them is 1.5 mm and fix it with an
attachment screw.
Do the same for connection B and proximity switch 2.
