Product details

8 mm non-flush sensing, NPN, cable — what it means on the line

The Siemens 3RG4023-0GB30 is an inductive proximity switch with an 8 mm sensing range in non-flush mounting — the target must approach from the face, not the side, because the field extends forward without side shielding. Output is NPN (sinking), normally open, with a direct cable connection — no quick-disconnect, so the cable length and routing are fixed at install. Rated for DC supply, this sensor fits standard 24 VDC control circuits in conveyor, packaging, or material-handling stations where a metal target presence is detected.

EOL hot — sourcing reality for this order code

Sourced through independent distribution and broker channels — quoted to order against your BOM quantity.

M18 barrel form factor — standard for inductive proximity sensors. The non-flush sensing face requires a free zone around the barrel. Cable exit is axial; the sensor body is sealed to IP67 when the mounting nut is torqued against the panel O-ring.

Frequently asked questions

What is the replacement for 3RG4023-0GB30?

The closest functional peer in the same Siemens inductive proximity family would be a non-flush M18 sensor with the same 8 mm range and NPN output, but with a different connector style or cable length — confirm the mounting and wiring before substituting.

How can I order the Siemens 3RG4023-0GB30?

This part is in EOL hot status and is sourced to order against your RFQ.
