Lanbao PR30-TM20 AC 2-Wire M30 Through-Beam Sensor

Lanbao PR30-TM20 AC 2-Wire M30 Through-Beam Sensor

Lanbao PR30-TM20-AC 2 Wires is an M30 cylindrical through-beam photoelectric sensor set for AC industrial automation systems. It uses separate emitter and receiver units to detect opaque objects that interrupt the optical path, making it suitable for longer sensing distances and stable beam-interruption detection.

This series is specified for 20m non-adjustable sensing distance, 20-250V AC supply, NO or NC receiver logic depending on part number, and 2-wire AC wiring. Available variants include fixed 2m PVC cable models and E2 M12 4-pin connector models, with infrared 880nm LED light source, IP67 protection, and a PBT housing reference in the official specification table.

Integration Notes & Hardware Guidance

• Power selection: This is an AC 2-wire photoelectric sensor series, so confirm that the input module, relay circuit, or controller accepts 20-250V AC sensor wiring.
• Beam alignment: Through-beam sensing requires correct emitter-to-receiver alignment; verify mounting distance, optical axis, and mechanical rigidity before commissioning.
• Logic selection: Choose the normally-open or normally-closed receiver version according to the required machine input logic.
• Load matching: Check receiver load current and residual voltage requirements before connecting the sensor to a PLC input, relay, counter, or indicator circuit.
• Connection selection: Choose fixed cable versions for direct wiring or E2 M12 connector versions when detachable wiring and easier sensor replacement are preferred.

FAQ

What detection mode does the PR30-TM20-AC Series use?

It uses through-beam detection, with an emitter and receiver mounted opposite each other. Objects are detected when they interrupt the beam path.

What sensing distance does this AC version support?

The official rated sensing distance reference is 20m non-adjustable.

Is this an NPN or PNP sensor?

No. This listing is for the AC 2-wire version. If your system requires NPN or PNP output, use the DC PR30-TM20 series instead.

How do I choose between cable and E2 versions?

Cable versions use a fixed 2m PVC cable, while E2 versions use an M12 4-pin connector for detachable wiring and easier sensor replacement.

Does this sensor require a reflector?

No. It is a through-beam series using an emitter and receiver pair rather than a reflector.
