• The maximum number of connections per Unit is as follows:
NX-SIH400: 4
• You can branch the connections to up to four Single-beam Safety Sensors for each test out-
put.

• The E3ZS/E3FS Single-beam Safety Sensor can be used in a Type 2 or lower or PLc or low-
er application. It cannot be used in a Type 3 or higher, or PLd or higher application.
• If you use more than one Single-beam Safety Sensor, it may not always be possible to detect
shorts between wires. Therefore, to satisfy safety category 2, the cables must be protected
from external damage for connections to single beam safety sensors. Use ducts or separate
cables for each system to protect the cables from external damage when you connect the
Single-beam Safety Sensors. You can also use special XS2F Cables for protection.
• The test period for a Single-beam Safety Sensor is 1,200 ms.
Use this value for reference to determine the standard compliance of your system.
