See Section 9.1.3 for additional limit switch data.
ND9000/K_
CLOSED
Connection diagram shows limitswitch when actuator is in intermediate position. Switch A (upper) is acti-
vated at the open limit of the travel and switch K (lower) at the closed limit.
Electrical characteristics:
OMRON D2VW-5 (K05):
5A - 30 V DC, 0.4 A - 125 V DC
3 A - 250 V AC
OMRON D2VW-01, gold-plated contacts (K06):
100 mA - 30 V DC / 125 V AC
Ambient temperature -40°...+80 °C / -40°...+176 °F
ND9000/I0_
CLOSED
Factory adjustment:
Active faces of proximity switches are covered when the actuator is in intermediate position. Active face A
(upper switch) becomes free at open limit of travel and face K (lower switch) at closed limit. The function can
be inverted on site by re-adjusting the cam discs.
Sensing distance 2...4 mm, depending on type of switch
Supply voltage 8 V DC (Ri 1 kΩ)
Current consumption
active face free, > 3 mA
active face covered, < 1 mA
