Proximity Sensors Capacitive
Thermoplastic Polyester Housing
™
Types CA, M12, DC, Teach-in
Capacitive proximity switches with a sensing distance
of either 4 mm flush mounted in metal or 8 mm nonflush mounted.
The switching points can
be altered by means of the
teach-in function. 3-wire DC
output with selectable make
(NO) or break (NC) switching
and NPN Alarm. Grey polyester housing with 2 m PVC
cable or M12 plug.

Adjustment Guide
The environments in which
capacitive sensors are
in stall ed can often be
un
stable as regards to tem-
perature, humi dity ,
object distance and industrial (noise)
inter ference. Because of
this, Carlo Ga vazzi offers
as standard features in all
TRIP LESHIELD™ capacitive sensors a user-friendly
sensitivity adjustment instead
of a fixed sensing range.
Likewise, these sensors
provide an extend ed sensing range to accommodate

The PNP- or NPN-load will be automatically
detected.
The functions described in the Teach-in
guide can be set up by means of the teach-in
wire.
It is possible to teach-in several sensors at
the same time by connecting the WH-wires
in parallel to the common ”BU -” supply.

Important: If the alarm output (WH-wire) is
unused, it has to be connected to +supply
