Frequently Asked Questions
What are the panel cutout dimensions and maximum panel thickness for this M12 rear mount socket?
This M12 rear panel mount receptacle requires a D-shaped anti-rotation cutout with a flat width of 13.5mm (+0.1/-0mm). The circular hole diameter is Ø15.3mm (+0.1/-0mm) for the PG9 thread version and Ø16.1mm (+0.1/-0mm) for the M16x1.5 thread version, accommodating a maximum enclosure panel thickness of 5.0mm.
How do the PCB solder pin lengths and contact diameters vary across different M12 codings?
For signal and low-voltage codings (A, B, D, and T Code), the PCB solder tail length (L1) is 6.0mm, whereas high-power codings (K, L, M, and S Code) feature a 5.0mm pin length. Contact pin diameters scale with current ratings: Ø0.6mm for 12/17-pin (1.5A), Ø0.8mm for 8-pin (2A), Ø1.0mm for 4/5/6-pin (4A–8A), and Ø1.5mm for power-coded 4/5-pin (12A–16A) versions.
What materials and sealing methods ensure IP67 protection in this M12 PCB receptacle?
The connector utilizes a nickel-plated copper alloy shell, a black polyamide (PA) insulator, and gold-plated copper alloy contacts for corrosion resistance. Ingress protection to IP67 (when properly mated) is achieved through a black silicone panel O-ring combined with internal black epoxy potting around the PCB solder pins, operating reliably from -40°C to +80°C.
Which IEC standards govern the electrical ratings of the signal and power M12 coding options?
The A, B, and D coded sockets comply with IEC 61076-2-101, supporting 30V DC to 250V DC and 1.5A to 4A for sensors and Industrial Ethernet. The K, L, M, S, and T power-coded sockets are engineered to IEC 61076-2-111, handling 63V DC to 630V DC and continuous currents from 8A up to 16A for industrial power distribution and motor drives.

Engineering Specifications & PCB Integration
Designed for rear panel mounting (locknut fastened from the front exterior or rear bulkhead interface), this M12 receptacle requires a D-shaped anti-rotation panel cutout with a flat edge dimension of 13.5mm (+0.1/-0mm) and a hole diameter of Ø15.3mm (+0.1/-0mm) for PG9 threads or Ø16.1mm (+0.1/-0mm) for M16x1.5 threads. The maximum supported panel thickness is 5.0mm. Depending on the selected coding, the PCB solder tail length (L1) measures 6.0mm for A/B/D/T-coding and 5.0mm for K/L/M/S-coding, with contact pin diameters ranging from Ø0.6mm to Ø1.5mm to match corresponding current capacities.
