Product details

The Siemens 3RG7134-3AA00 is a SIMATIC PXO250 M18 diffuse sensor with background suppression, built for detecting objects against a defined backdrop. It switches PNP dark-on at 200 mA over a 10-120 mm sensing range, powered by 10-36 V DC. The M12 4-pole connector and IP67 rating make it a straightforward swap on a machine that already has a compatible cable.

The 10-120 mm sensing range is the adjustable background-suppression window — the sensor ignores objects beyond that set point, which is critical on conveyors or pick-and-place stations where a shiny background could false-trigger a standard diffuse sensor. The PNP dark-on output means the load is switched when the sensor sees its target (dark condition), so confirm your PLC input card expects a sourcing signal. IP67 holds up to washdown, but check the cable gland seal if the M12 connector is not pre-wired — moisture ingress at the connector is the most common field failure on these.

Frequently asked questions

What is the closest functional alternative to this sensor?

There is no official successor order code. A current-production M18 diffuse sensor with background suppression, PNP dark-on output, and an M12 connector would be the closest functional match — verify the sensing range and mounting dimensions before substituting.

What are the key specifications of the 3RG7134-3AA00?

It is a SIMATIC PXO250 M18 diffuse sensor with background suppression, rated 10-36 V DC, 10-120 mm sensing range, PNP dark-on output at 200 mA, with an M12 4-pole connector and IP67 ingress protection.
