GuardShield Micro 400 Safety Light Curtains
The M12 connector (male)/M12 8-pin connector (female) [shielded
cable], extension connection cable or to use between light curtain
cascades are shown in
Figure 15
.

Dimensions [mm (in.)]
Power supply, inputs, safety outputs, and status outputs are connected to
the terminal block of the MSR41, MSR42 controller, or a MSR45E (see
Figure 16
and
Figure 17 on page 14
).
The interfacing of the light curtain with the machine control has to be
control reliable. For example, a correct interface with a safety PLC or
safety relays with positive guided relay contacts.

IMPORTANT
The safety devices and the interconnection to the machinery
have to comply with the basic safety requirements as
mentioned in the current regulations and standards.
Direct interface of a safety light curtain to a machine control
that does not meet the necessary safety integrity level, can
result in injury to personnel. For instance, use of general-
purpose PLCs or relays can cause injury to personnel.
