Differentiation of the C&P20 head variants
The C&P20/A/M and the C&P20 P head differ in many details. They are easily identified by the following
features:
1. The C&P20 P can be identified by the fan. This fan is not present on the C&P20/A/M heads.
2. The component sensor is flatter and wider on the C&P20 P than on the C&P20/A/M.
CAUTION
Do not confuse the different C&P20 head variants.
► Parts from the C&P20/A/M head can not usually be used for the C&P20 P head (and vice
versa)!

C&P12 Placement Head - Special Features
When retrofitting the vacuum pump option, the Venturi vacuum generator for the C&P6/12 head is re-
placed with the retrofit kit vacuum pump C+P6/12 [00119796-xx].
The holding circuit is therefore operated permanently via the vacuum pump.
The placement circuit continues to generate its vacuum with compressed air according to the Venturi
principle.
When the placement head is in waiting position, the star is between two star positions (half-cycle). In this
intermediate position, the holding and pickup cycles are interconnected via the cross-section, leading to
an increased vacuum consumption.
The "vacuum consumption" of the placement machine depends only on the number of placement heads
and the size of the nozzles.
The more C&P12 heads are connected to the vacuum pump, the lower the vacuum level will be at the
nozzles.
When the placement operation begins, the vacuum increases with each component picked up. An aver-
age vacuum value will soon form, based on the number of nozzles closed at the same time (with picked
up components) and number of nozzles open (components placed).
