The FTREFL03 reflex photocells from Domotime are a reliable solution for infrared reflex detection, ideal for automation systems such as gates, barriers, and doors. With 740 nm IR technology and a range of up to 17 m, they ensure safety and stability in various environments.
🔹 FTREFL03 – Precise and safe reflex detection
The FTREFL03 model is a reflex photocell with integrated transmitter and receiver, using a reflector to return the signal. Compatible with most control units, it features a compact design (100 × 40 × 35 mm) for discreet installations.Main technical specifications
- Power supply: 9–24 V AC / 12–24 V DC
- Consumption: <35 mA (at 12 V DC) – <19 mA (at 24 V DC)
- Wavelength: 740 nm (infrared)
- Maximum range: ≤ 17 m
- Relay contact: 0.3 A – 120 V AC / 0.8 A – 30 V DC
- Operating temperature: –25 °C to +70 °C
- Dimensions: 100 × 40 × 35 mm
⚙️ Simple and intuitive installation
The installation of the FTREFL03 is quick and safe, based on the reflex principle:- Position the sensor and reflector facing each other, aligned and perpendicular to the ground.
- Connect the power supply to the + and – terminals (9–24 V AC / 12–24 V DC).
- Set the jumper for NO or NC relay output (OUT for COM, the other for NO/NC).
- When the beam is stable, the green LED lights up; if interrupted, the red LED turns on.
- Avoid highly reflective surfaces nearby (>90%) to prevent false signals.
🔧 Technical tip: In fog or heavy rain, the range may be reduced; clean the lenses regularly to maintain efficiency.
⚠️ Important warnings
- Carefully read the manual before first use.
- Ensure the power is disconnected during installation (no integrated fuse).
- Use the product only within the intended operating range to avoid risks.
- Protect from fog, smoke, and heavy rain that reduce the range.
- Avoid unstable installations to prevent misalignment due to vibrations.
🔍 Quick troubleshooting
| Problem | Possible cause | Solution |
|---|---|---|
| Green LED not on | Misalignment or dirty reflector | Check alignment and clean the reflector |
| No relay response | Incorrect wiring or missing power | Check connections and power supply |
| Reduced range | Adverse weather conditions or nearby reflective surfaces | Clean the lenses and remove interference |
| Unstable signal | Vibrations or misalignment | Reinforce fixing and realign |
