Electrical

Technical data for the grips switch EC2000

• Switching capacity

– minimal current resistive load 100mA at 12VDC or 24VDC

– maximal current resistive load 5A at 12VDC or 24VDC

• Microswitch lifetime

– resistive load at 12VDC 100 to 500mA 5 millions cycles

5A 300000 cycles

– resistive load at 24VDC 100 to 500mA 3 millions cycles

5A 150000 cycles

– inductive load L/R=5ms at 12VDC or 24VDC 1,25A 200000 cycles

• Maximal contact resistance m Ω 20

• Switching on/off with low loads

– minimum voltage V 12

– minimum current strength mA 100

• E-contact type high current

Grip protection IP65

Switching guidelines for DC voltages to ensure the service life of the electrical switch, we

recommend the use of free-wheeling diodes that are switched

parallel to the inductivity.

• Power supply for the locking solenoids V 12 V (9 to 15) and 24 V (20 to 27) / DC

• Max. power consumption of each solenoid W 13,5 at 12 VDC or 24VDC

Mechanical

Back pressure at port T bar up to 3

Pilot oil flow (P to 1 - 2 - 3 - 4) l/mn up to 13

Pressure fluid
