The M12 L-coded connector is the power version of the M12 family. It carries up to 16 A at 63 V through 4 power contacts plus a functional earth – enough to feed an IO-Link hub or a bank of sensors from one cable instead of running separate power to each device.
We stock L-coded connectors in male and female, field-wireable and overmoulded, straight and angled, plus panel-mount versions for power supply ports.
Key specifications
| Parameter | Value |
|---|---|
| Poles | 4 + FE (functional earth) |
| Voltage / current | 63 V / 16 A |
| IP rating (mated) | IP67 |
| Standard | IEC 61076-2-111 |
Why not just use an A-coded M12 for power? Because A-coded tops out around 4 A. Once you need to distribute power to a cluster of devices, L-coded is the interface that does it without a junction box full of terminals.
Typical topology
A common layout runs one L-coded feed to an IO-Link hub or field distributor, then A-coded drops to the individual sensors. That keeps the power cable count down to one per zone instead of one per device.
Frequently asked questions
What’s the difference between L-coded and K-coded?
Both are M12 power codes. L-coded is 63 V / 16 A and the more common choice. K-coded is 63 V / 12 A and used mainly in specific Asian automation ecosystems.
Can I feed it from a 24 V supply?
Yes, 24 V DC at up to 16 A is a standard L-coded application.
Do you supply the mating receptacle?
Yes, male cable connectors and female panel-mount receptacles are both stocked.
