At a Glance

Brand	Siemens
Model	6ES7392-1AM00-0AA0
Product Type	Front connector
Core Function	Detachable field wiring
Application	S7-300 cabinet I/O connections

40-pole format

Connect the field conductors for compatible 32-channel signal modules and CPU 31xC onboard I/O.

Controlled screw termination

Use a conical 3–3.5 mm screwdriver and a tightening torque of 0.4–0.7 N·m.

Compact wire preparation

Prepare 6 mm stripped ends and select conductors within the 0.14–0.75 mm² terminal range.

Product Overview

6ES7392-1AM00-0AA0 connects sensors and actuators to compatible SIMATIC S7-300 hardware through a removable 40-pole screw-terminal assembly.

Its termination geometry suits closely spaced field conductors, while the detachable connection provides a defined interface between the field harness and the module.

Ordering focus: For 32-channel S7-300 signal modules and CPU 31xC installations requiring a 40-pole screw connector.

Key Functions

Connect dense I/O wiring

Forty poles provide the field connection format used by compatible 32-channel signal modules and compact CPU I/O.

Secure prepared conductors

Screw terminals accept solid or flexible 0.14–0.75 mm² wires, including correctly sized ferruled conductors.

Keep terminations consistent

A 6 mm stripping length and 0.4–0.7 N·m torque give technicians defined wire preparation and tightening targets.

Frequently Asked Questions

Can I use 6ES7392-1AM00-0AA0 on a CPU 31xC?

Yes, the 40-pole screw version is assigned to CPU 31xC onboard I/O and compatible 32-channel S7-300 signal modules.

Does 6ES7392-1AM00-0AA0 support Controlled screw termination for mobile equipment?

No, the terminal range for this article ends at 0.75 mm², so use conductors within 0.14–0.75 mm².

How much insulation should I remove for 6ES7392-1AM00-0AA0?

Strip 6 mm so the conductor end matches the specified terminal preparation length.

Can I combine two small wires in 6ES7392-1AM00-0AA0?

Two conductors may share one ferrule when their combined cross-section does not exceed 0.75 mm².

What torque should my technician use on 6ES7392-1AM00-0AA0?

Tighten the terminal screws to 0.4–0.7 N·m with a conical 3–3.5 mm screwdriver.

Which ferrule collar length is suitable for 6ES7392-1AM00-0AA0?

Use DIN 46228 Form E insulated ferrules up to 6 mm long or Form A uninsulated ferrules 5–7 mm long.

How should I store spare 6ES7392-1AM00-0AA0 connectors?

Keep the connectors within the specified storage and transport temperature range of −40 to +70 °C.

Compatibility & Ordering Notes

Before ordering 6ES7392-1AM00-0AA0: Match the 40-pole format to the S7-300 module socket and its terminal assignment, then size the field wiring for the 0.75 mm² upper limit of this connector.

Compatibility Checklist for 6ES7392-1AM00-0AA0

• Select the 40-pole screw version required by the module.
• Prepare 6 mm stripped conductor ends.
• Keep a shared ferrule within 0.75 mm² total cross-section.
• Use the specified screwdriver and 0.4–0.7 N·m torque.
