FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why did PI (PROFIBUS & PROFINET International) standardize on M12 L-coded connectors instead of 7/8″ mini-change connectors?
M12 L-coded (IEC 61076-2-111) delivers 16 A at 63 V DC across four 2.5 mm² power pins plus a leading Functional Earth (FE) pin in a footprint 40 % smaller than a 5-pin 7/8″ connector, allowing compact IP67 PROFINET and EtherCAT I/O modules to daisy-chain two independent 16 A 24 V DC power rails (U_S logic and U_A actuator power).
What is the difference between M12 L-coded and M12 K-coded power connectors?
M12 L-coded has 4 power pins + 1 Functional Earth (FE) rated for 63 V DC / 16 A (low-voltage DC fieldbus power). M12 K-coded has 4 power pins + 1 leading Protective Earth (PE) with higher creepage and clearance distances rated for 630 V AC / 16 A (6 kV impulse), designed for 3-phase 400/480 V AC motors and frequency inverters.
When should I choose 2.5 mm² (14 AWG) over 1.5 mm² (16 AWG) for M12 L-coded daisy chains?
At 16 A DC, 1.5 mm² cable drops 0.43 V per metre (loop), whereas 2.5 mm² drops only 0.26 V per metre. Use 2.5 mm² whenever total daisy-chain trunk length exceeds 8–10 m to keep 24 V DC actuator voltage above the 20.4 V minimum threshold.
Are L-coded and K-coded plugs mechanically prevented from mating with standard M12 A-coded or D-coded sockets?
Yes. IEC 61076-2-111 defines distinct L-shaped and K-shaped polarization keyways that cannot mate with A, B, D, X, Y, S, or T-coded M12 connectors, eliminating any risk of applying 24 V/16 A or 630 V AC to signal ports.
