A7VO Series 63

| Axial piston variable pump

Connector for solenoids

Connector for solenoids

DEUTSCH DT04-2P-EP04

Molded connector, 2-pin, without bidirectional suppressor
diode
There is the following type of protection with mounted
mating connector:

▶ IP67 (DIN/EN 60529) and

▶ IP69K (DIN 40050-9)

▼ Circuit symbol

▼ Mating connector DEUTSCH DT06-2S-EP04

Consisting of

DT designation

1 housing

DT06-2S-EP04

1 wedge

W2S

2 sockets

0462-201-16141

The mating connector is not included in the scope of
delivery.
This can be supplied by Bosch Rexroth on request (material
number R902601804).

Note

If necessary, you can change the connector orientation by
turning the solenoid housing.
The procedure can be taken from the instruction manual.
