105M12 Industrial Ethernet Switch
The 105M12 is an unmanaged industrial Ethernet switch providing five Fast Ethernet copper ports in an
IP65/IP67 rated enclosure for protection against temporary immersion in water. The switch provides
Category-5 compliant 10/100BaseTX connections with IP65/67 rated M12 D-code connectors for high
performance network design, and hub/repeater upgrades. The switch is capable of auto negotiating 10/100
Mb and half/full duplex communications.
108M12 Industrial Ethernet Switch
The 108M12 is an unmanaged industrial Ethernet switch providing eight Fast Ethernet copper ports in an
IP65/IP67 rated enclosure for protection against temporary immersion in water. The switch provides eight
Category-5 compliant 10/100BaseTX connections with IP65/67 rated M12 D-code connectors for high
performance network design, and hub/repeater upgrades. The switch is capable of auto negotiating 10/100
Mb and half/full duplex communications.

INGRESS PROTECTION IP67
The classification of degrees of protection provided by the enclosures is defined by IEC 60529. Each rating is
defined by specific tests.
The IP number is comprised of two numbers, the first referring to the protection against solid objects and the
second against fluids. The higher the number, the better the device is protected against contact with moving
parts and the harmful entry of various forms of moisture.
1st IP
Protection against ingress of solids
2nd IP
Protection against ingress of liquids
0
No protection
0
No protection
1
Protected against solid objects over 50mm e.g. hands,
large tools.
1
Protected against vertically falling drops of water.
2
Protected against solid objects over 12mm e.g. hands,
large tools.
2
Protected against direct sprays of water up to 15° from
vertical.
3
Protected against solid objects over 2.5mm e.g. wire,
small tools.
3
Protected against direct sprays of water up to 60° from
vertical.
4
Protected against solid objects over 1.0mm e.g. wires.
4
Protected against water sprayed from any direction.
Limited ingress permitted.
5
Limited protection against dust ingress (no harmful
deposit)
5
Protected against low pressure water jets from any
direction. Limited ingress permitted.
6
Totally protected against dust ingress.
6
Protected against high pressure water jets from any
direction. Limited ingress permitted.
7
Protected against temporary immersion between 15cm
to 1m.
8
Protected against long periods of immersion under
pressure.
The 105M12 and 108M12 Industrial Ethernet Switches are fully protected against dust and will remain sealed
when immersed in water to a depth of 1 meter for 1 hour when all the ports are properly mated or sealed.
These IP67 caps seal off the unused ports protecting them from dirt, water, oil or any other
contaminants which might be present in the close proximity of the switch.

APPLYING POWER
The M12 A coded power connector is keyed, where the mating connection from the power supply can
be made only when the male and female ends are lined up properly.
When the power is first connected all LED’s will flash ON Momentarily.
Verify the Power LED stays ON (GREEN).
Note: Either V1or V2can be connected to power for minimal operation. For redundant power
operation, V1and V2 must be connected to separate DC Voltage sources. The power cord should be
limited to less than 10 meters in order to ensure optimum performance.
Recommended 24V DC Power Supplies, similar to:
100VAC/240VAC:
N-Tron NTPS-24-1.3, DC 24V/1.3A

N-TRON 105M12 AND 108M12 GROUNDING TECHNIQUES
Drain wire with lug connecting switch chassis to known grounding point.
CONNECTING THE UNIT
For 10Base-T ports, plug a Category 3 (or greater) twisted pair cable into the M12 connector. For
100Base-T ports, plug a Category 5 (or greater) twisted pair cable into the M12 connector. Connect the
other end to the far end station. Verify that the LNK LED’s are ON once the connection has been
completed. To connect any other port to another Switch or Repeater, use a standard Cat5 straight
through or crossover cable.
Warning: Creating a port to port connection on the same switch (i.e. loop) is an illegal operation and
will create a broadcast storm which will crash the network!
TROUBLESHOOTING
1. Make sure the (Power LED) is ON.
2. Verify that Link LED’s are ON or BLINKING for connected ports.
3. Verify cabling used between stations.
4. Verify that cabling is Category 5 (or greater) for 100Mbit Operation.
