1. INTRODUCTION
This specification contains the regulation to assemble the M12 Rail connectors.
All units noted in this specification are by default in millimeters, grams, Newton and Newton Meter.
2. CAUTION
Do not connect or disconnect the connector under electrical load.
The use of lubricants or oils during mounting unless specified are prohibited.
Any kind of pollution (dust, humidity, etc…) during the assembly process can degrade contact and connector
performance. This applies in particular to the seal and the crimping of the contacts.
Failure to follow all instructions in Application Specification including using only approved TE tooling (if
applicable) can result in improper installation and/or crimping which is dangerous and may cause or
contribute to electrical fires.
3. GENERAL INSTRUCTIONS (HANDLING AND SAFETY)
Personal Protective Equipment (PPE) is mandatory and must be worn when carrying out
hazardous tasks.
Ensure your safety and the safety of others.
Environment
TE Connectivity and its subsidiaries, affiliates, and operating units (collectively, the “Company”)
are committed to protecting the environment. Always act responsibly and follow local guidelines
and recycling policies to help protect the environment.

4. SYNOPTIC OF THE M12 RAIL CONNECTOR
This synoptic aim to show the possible configurations of connection between M12 male and female connectors.
M12 male connectors can mate with M12 female connectors with respective codes. For example, M12 male
D4 code connector can mate with M12 female D4 code connector. The mated connectors meet an ingress
protection rating of IP67.

9.8. Insert the contacts into contact positioner
For D4 code, If 2 pair (4 wire) cable used, twist the wires together White & Blue and Orange & Yellow. If
other cable used {4 pair (8 wire) cable}, keep only White orange, Orange, White green and Green wires and
twist the wires together White orange & Orange and White green & Green and remaining wires cut it down.
*Similar for A8 code, but no need to cut any wires. The twisting of wire pairs should be White Blue & Blue,
White Brown & Brown, White Orange & Orange and White Green & Green. Once contacts crimped with
wires, twist the wire pairs as mentioned before inserting into contact positioner.
*For A5 code, keep only White orange, Orange, White green, Green and Brown and remaining wires cut it
down. Twist the wires together White orange & Orange and White green & Green. Connect Brown wire
directly to center contact.
Insert the contacts into contact positioner and place the contacts into provision given in contact positioner. For
center contact, insert into center hole and pull the contact from front side of the hole of contact positioner.
