Compact Through-Beam Sensor

The Autonics BJ10M-TDT-C is a through-beam photoelectric sensor designed for industrial detection tasks. It operates on a 12-24VDC power supply with a 10m sensing range. The unit uses a red LED light source at 660nm to detect opaque objects of at least 12mm diameter. Its compact housing suits tight mounting spaces.

Switchable Output Logic

A built-in selector switch lets installers choose between Light ON and Dark ON operation modes without rewiring. The control output uses an NPN open collector configuration compatible with standard PLC inputs. Maximum response time is 1ms for reliable high-speed counting or positioning. The sensor includes a 3-year parts and 1-year labor warranty from the manufacturer.

Ideal For Simple Presence Detection

This sensor suits automation engineers needing a basic through-beam pair for conveyor monitoring or access control. Buyers who require PNP output logic should select a different model. Applications demanding longer range, background suppression, or analog output will need alternative sensing technologies. The single-unit pack assumes the receiver or emitter counterpart is sourced separately.

Questions about this item

Does the 10m through-beam sensor need periodic lens cleaning to maintain its 12-24VDC operation?

Yes, keep the emitter and receiver lenses free of dust or oil; a soft dry cloth is enough and no internal parts require scheduled replacement.

What limits continuous detection at the full 10m range when the red 660nm LED runs all day?

The 1ms maximum response time is the first constraint; faster line speeds may need a sensor with a shorter response.

How much heat does the PNP open-collector output generate during 24VDC all-day use?

Power draw stays within the 12-24VDC ±10% supply with 10% max ripple, so self-heating is minimal and no extra cooling is needed.
