Description
The Siemens 6ES7392-1AJ00-0AA0 is the 20-pole screw-terminal front connector for 20-pin S7-300 signal modules, such as the 16-channel SM 321 and SM 322 and the SM 331 analog input module. Siemens's data sheet gives conductor cross-sections of 0.25 to 1.5 mm² (AWG 24 to 16), a stripped length of 6 mm and a tightening torque of 0.4 to 0.7 N·m. Its 40-pole twin, the 6ES7392-1AM00-0AA0, fits 40-pin modules and takes thinner wires (0.14 to 0.75 mm²). Siemens's data sheet marks it as a spare part.
Application: Front connector for S7-300 signal modules
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7392-1AJ00-0AA0 used for?
It is the wiring side of an S7-300 I/O module: the field cables land on it, and it plugs onto the module's front.
Key features
- 20-pole front connector for S7-300 signal modules
- Screw terminals
- Conductors 0.25 to 1.5 mm² (AWG 24 to 16)
- One wire per terminal, or two up to 1.5 mm² in total in a shared ferrule
- Discontinued by Siemens on 1 October 2025; spare part only

Product Questions
Is the 6ES7392-1AJ00-0AA0 discontinued?
Yes. Its manufacturer lifecycle status is Discontinued.
Can another Siemens SIMATIC S7-300 part replace it?
Potential replacements must be checked against the required ratings, dimensions and connections. Sharing a family name does not establish interchangeability.
Do you ship worldwide?
Yes. TimControls ships worldwide. Parts usually ship within 3 to 7 working days of order confirmation, and the exact lead time and shipping options are stated on your quote. Include your delivery country and postal code when you ask for a quote.
