Tensility’s M12 connector and wire line is designed for high-power delivery in demanding industrial and automation environments. With S, T, and L coding options, these connectors support ratings up to 12.0 A and 630 V, providing reliable high-current connections in harsh conditions.
(See diagram below for coding pin layouts.)

The line includes multiple mounting styles—molding, flange, assembly, and panel mount options—for flexible integration across designs. Paired with UL 21767-rated wire, this solution supports 600 V power transmission in 3C, 4C, or 5C formats and 16–32 AWG sizes. The wire’s TPU jacket provides UV, oil, and abrasion resistance and withstands -40~105 °C, ensuring durability in outdoor and industrial use. Together, the M12 connectors and wire offer a complete, robust solution for power-critical systems across industrial automation, energy, and transportation.

What’s the difference between S, T, and L coding in M12 connectors?
S-coding supports high-voltage power (up to 630 V AC), T-coding supports 63 V DC for data/power hybrid systems, and L-coding is optimized for high-current industrial power delivery.
Can these connectors handle both AC and DC power?
Yes. S-coding supports up to 630 V AC, while T- and L-coding configurations handle up to 63 V DC for power-specific applications.
What’s the benefit of UL 21767-rated wire?
It ensures 600 V high-voltage performance, VW-1 flame rating, and oil/UV resistance—critical for safe use in harsh industrial settings.
What’s the advantage of the TPU jacket on the wire?
TPU offers superior flexibility and toughness, with resistance to abrasion, oil, and UV damage, and operates reliably from -40 to 105 °C.
Are these connectors IP67-rated?
Yes, when fully mated, the connectors are IP67 dustproof and waterproof.
How many insertion cycles can these connectors handle?
Tested for 500+ cycles, ensuring long-term reliability in demanding applications like automation or heavy machinery.
