The Siemens 3RG7210-6MC18 is a SIMATIC PXO610 K80 diffuse sensor, built for energetic detection in industrial automation. It runs on universal control voltage UC 20-320V, switches via a 2-meter relay with C-contact antivalent output, and includes an adjustable timer covering 0.1 to 10 seconds. The housing measures 83x61x25 mm, terminates in a 5-pole PG11 gland, and carries an IP67 rating.
What the Ratings Mean for Fit
The UC 20-320V supply covers both AC and DC control circuits common in European panel builds — no separate power supply module needed for the sensor. The relay output gives a dry contact, so it can switch a PLC input or a contactor coil directly without an interposing relay. The C-contact antivalent (changeover) provides both normally-open and normally-closed signals from one sensor, useful for fail-safe logic where the NC side reports sensor health. The timer (0.1-10 s) delays the output, which can suppress false triggers from passing objects or vibration. The PG11 gland accepts cable diameters around 6-10 mm; plan for a 5-wire connection (supply, common, NO, NC, and shield if used).
