mental resistance and may come loose from vibration. Do not use pliers or
other tools to tighten the connectors, because the tools may damage the
connectors.
3. Always cap unused connectors with an XS2Z-12 Waterproof Cover or
XS2Z-15 Dust Cover, shown in the following diagram.
XS2Z-12 Waterproof Cover
The connector will meet IP67
standards if a Waterproof Cover is
attached. Tighten the connector by
hand to a torque of 0.39 to 0.49 N ⋅ m.
Maintaining Environmental Resistance
• The IP67 environmental resistance level will be lost if the surfaces where
the contact block and cover meet are subjected to excessive force. Pro-
tect the contact block and cover from excessive force or shock.
• The IP67 standard is not completely waterproof. Do not submerge the
system components.
• The body of the components is plastic resin. Do not place objects on the
components or allow the components to be stepped on.
Note There are two kinds of wiring for OMRON 2-wire Proximity Switches (pre-
wired with connector). One kind has IEC pin allocation (M1GJ type) and the
other has OMRON pin allocation (M1J type). Refer to the following table to
determine the appropriate Waterproof Terminal to use with each kind of
switch.

The B7AC Interface Unit acts as an interface between I/O Connector-type
B7AC Link Terminal Units and the DeviceNet Master Unit. Up to 3 B7AC Link
Terminal Units (3 Units × 10 inputs/Unit) can be connected to the B7AC Inter-
face Unit.
The B7AC Interface Unit uses shielded connectors to connect to both the
DeviceNet Master Unit and B7AC Link Terminal Units, so the cable connec-
tions can be made easily without tools and the connections meet the high
IP66 environmental resistance standards.
This section explains the B7AC Interface Unit's node address and baud rate
settings. These settings are made using the following pins on DIP switch 1.

XS2Z-15 Dust Cover
Press the Dust Cover onto the
connector firmly. The Dust Cover
will protect the connector from dust,
but does not meet IP67 standards.
