• Simplified Installation – Comes with mounting bracket, bolts, and 2 m pre-wired cable for quick setup.

• Low-Light Resilience – Designed to perform under varying ambient illumination.

• Maintenance‑Friendly – No sensitivity adjustment needed (fixed), reducing configuration time.

Typical Applications

• Conveyor Systems – Detects products in transit for counting or sorting.

• Packaging Lines – Confirms presence or passage of items.

• Automated Assembly – Ensures part presence, orientation, or flow.

• Security Barriers – Acts as a beam-break sensor for access control.

• Material Handling – Tracks pallets, cartons, or workpieces in manufacturing.

How to Use

1. Mounting

   • Install the emitter and receiver facing each other across the detection zone using the included bracket and fasteners.

2. Wiring

   • Connect both units to the 12–24 V DC supply (observe polarity).

   • Wire the NPN output from the receiver to your controller or PLC input.

3. Operation

   • Upon powering the system, verify that the receiver receives the emitter's beam.

   • The NPN output switches on (and indicates via LED) when the beam is broken by an opaque object entering the sensing path.

4. Testing & Verification

   • Validate functionality by passing a test object through the beam; ensure rapid response and correct output signaling.

5. Maintenance

   • Clear any dust or obstruction from sensor face as needed.

   • Periodically verify alignment and tightness of hardware.

Summary

The Autonics BM3M‑TDT1 is an efficient, value-driven photoelectric solution for industrial detection across a 3‑meter range. Its sleek design, fast response, and reliable performance make it an excellent choice for everyday automation tasks. Whether you're integrating it into conveyors, packaging machinery, or safety systems, this sensor delivers consistency with minimal setup effort.
