Description
Wiring up a high-density I/O module for a SIMATIC S7-300 rack? The Siemens 6ES7392-1AM00-0AA0 is a 40-pin front connector designed to establish secure, point-to-point electrical connections between field sensors/actuators and the internal circuitry of your PLC signal modules. Utilizing a screw-termination mechanism, this connector eliminates the need for external terminal blocks, allowing field wires to hook directly into the module faceplate.
We maintain a substantial inventory of brand new, factory-sealed components ready to support your next control panel build or maintenance turnaround.

Field Deployment Notes: Terminal Grouping and Coding Elements
Are you using crimped wire ferrules? In field deployments featuring S7-300 high-density modules, choosing between bare stranded wire and insulated ferrules impacts your packing space inside the connector housing. If you use plastic-collared ferrules on all 40 channels, the wire bundle becomes incredibly bulky. You will find it difficult to snap the plastic wiring door shut without pinching the insulation.
Well, technically the connector handles up to 1.5 mm² wires, but only if you omit the ferrules or use thin-walled uninsulated sleeves. For heavily packed enclosures, dropping down to a 0.5 or 0.75 mm² wire size makes routing significantly more manageable.
Important Hardware Detail: When inserting the connector into the signal module for the first time, look closely at the mechanical “coding keys” included with the unit. The first time you press the connector into its final operating depth, these plastic pins lock into a unique pattern matching that specific module type (e.g., a DI module vs an AO module). If someone later tries to plug this wired connector into a different module during a frantic midnight troubleshooting session, the coding keys physically block insertion—preventing high-voltage digital outputs from accidentally blowing up low-voltage analog inputs.
Global Trade and Shipping Logistics Guide
Moving bulk automation accessories requires correct customs declaration profiles to avoid processing holds at international sorting hubs.
1. Export Control & Trade Tariff Details
The Siemens 6ES7392-1AM00-0AA0 is classified purely as a mechanical electrical accessory, exempt from complex dual-use data or encryption export restrictions.
- HS Code: 85366990 (Plugs and sockets for a voltage not exceeding 1,000 V)
- ECCN: EAR99 (No export license required for most destinations)
2. Incoterms and Consolidation Strategies
We typically supply these accessories under EXW (Ex Works) or CIP (Carriage and Insurance Paid To) terms. Because these units are light but crucial for completing installation projects, we frequently consolidate them with their corresponding S7-300 signal modules into a single air-freight shipment to drastically reduce your destination customs clearance overhead.
3. Material Verification and Packaging
To guarantee pins arrive perfectly aligned without bending during shipping, connectors are kept inside their original Siemens thin-walled boxes, which are then packed inside heavy-duty, outer shipping cartons lined with dense anti-crush bubble wrap.
Frequently Asked Questions
- Does this connector include the plastic front door cover?
No. The 6ES7392-1AM00-0AA0 is the internal 40-pin terminal block assembly itself. The pivoting plastic front cover that conceals the wiring is shipped as part of the SIMATIC S7-300 signal module, not with the front connector accessory.
- Can I use this 40-pin connector on a 20-pin signal module?
No. Siemens S7-300 modules use either a 20-pin or a 40-pin interface depending on their channel density. A 40-pin connector will not physically align or fit into the front faceplate slot of a 20-pin module (such as the 6ES7321-1BH02-0AA0).
- Is there a spring-loaded version of this connector available?
Yes. If your plant facility standardizes on vibration-resistant spring terminals rather than screw connections, you should specify part number 6ES7392-1BM00-0AA0 instead.
