M12 S-coded versus T-coded power

Is the documented four-position M12 power interface S-coded or T-coded?

Computer-generated illustration, not a photograph. — P266 · ConnectorM12 S-coded 4-position power connector

How they differ

M12 S-coded 4-position power connector Confirm S coding and the four-position insert from exact documentation before using this record as an identification candidate.
M12 T-coded 4-position DC power connector Identify the T-coded keying and four-position insert from the exact component documentation before assigning a power role.

Then askIs the documented four-position M12 power interface S-coded or T-coded?

M12 S-coded 3-position versus 4-position powerWhich exact S-coded position count does the documented M12 power interface require? Connector identity and manufacturer ratings are only reference layers; exact circuit, wiring, installation and equipment requirements still need qualified documentation.USB-C vs USB Power DeliveryConnector shape and negotiated power are different layers. A USB-C port does not by itself establish a particular USB Power Delivery capability.IEC 60320 C1 versus C2Is the part the C1 cord connector or C2 appliance inlet? Use the exact component identity; this comparison is not wiring or installation guidance.IEC 60320 C15 versus C15A connectorsIs the cord connector C15 or the distinct C15A very-hot-condition form? Similar naming is not permission to substitute or modify a mains cord.IEC 60320 C16 versus C16A inletsIs the appliance inlet C16 or the distinct C16A very-hot-condition form? Similar naming is not an installation or substitution verdict.IEC 60320 C19 versus C21 connectorsIs the cord connector C19 or C21? Both occur in the higher-current IEC 60320 family, but exact configuration and equipment requirements remain separate.
