Multiple Limit Switch
VB
A New Monoblock Multiple Limit Switch
Incorporating a Head Box with a Tough Head
and Ensuring High Sealing Performance and
a Mechanical Durability of 5,000,000
Operations
• Used for the sequential control of a variety of engineering ma-
chines and belt conveyor lines.
• Built-in oil filter shuts out oil and water.
• Approved by EN, IEC, and CCC (Chinese standard). (Ground
terminal models only.)
• Ground terminal models bear the CE mark.

Note: 1.
Other than the above models, minute load models switching 0.1 A are available. When ordering a minute load model, add the suffix A to
the model number (i.e., VB-2211A for example).
2.
SC connectors can be connected to VB models.
3.
Models with ground terminals are also available. When ordering a ground terminal model, add the suffix E to the model number (i.e., VB-
2211E for example).
4.
Since the actuator is incorporated into the monoblock switch, the actuator cannot be replaced.
