1. Photoelectric Beam Detector NRTS Series

2. 2 １． Outline Dual beam detector NRTS series is a part of Red Barrier series. * 30m 60m 90m (Outdoor) range *6 0m 120m 180m (Indoor) range

3. 3 ２． Functions & Features (1) Two Beams (2) High Grade Spherical Fresnel Lens ① Sharp focused beam ray (a) Allows 100 times sensitivity (b) Minimizes unnecessary beam reflection. (c) Minimizes receiving unnecessary external light. ② Cut the unnecessary external lights ③ Integrated optical scope (a) Matches beam and scope direction (b) Shows the clear sharp target

4. 4 (3) 100 times sensitivity allowance (4) Easy optical alignment (5) IP rate : IP55 (6) Adjustable Beam Interruption Time (7) AGC (Auto Gain Control) (8) Unique Knockout Structure (9) Mount bracket (10) Heater (Option)

5. 5 (1) Twin Beams offers stable Operation When the bugs, falling leaves or other flying objects block the one beam, other one beam still can keep unit correctly without making false alarms.

6. 6 (2) High Grade Spherical Fresnel Lens TransmitterReceiver Lens

7. 7 ① The sharp focused beam ray at long distance achieves (a)100 times sensitivity allowance. This high grade lens focuses the beam ray on the receiver without the big beam power loss. * Refer to (3) for further detail.

9. 9 (b) Minimize unnecessary beam reflection NRTS Lens

10. 10 Normal Lens

11. 11 (c) Minimizes receiving unnecessary external light.

12. 12 ② Cut the unnecessary external lights

13. 13 ③ Integrated optical scope Scope TransmitterReceiver (a) Matches beam and scope direction The beam and scope direction is same and fixed as the scope is integrated on the lens.

14. 14 (a) Matches beam and scope direction The beam and scope direction is same and fixed as the scope is integrated on the lens. Scope direction Beam direction Easy to align Difficult to find the target

15. 15 (b) Shows the clear sharp target The well designed scope offer the very clear target image. Therefore it is very easy to align the optics. Clear imageUnfocused image

16. 16 (3) 100 times sensitivity allowance Stable operation is maintained even if 99% of beam power is lost by rain, snow, fog, dust or other objects.

18. 18 (a) Scope for Rough Alignment (4) Easy Optical Alignment

19. 19 (b) LED Level Indicator for Fine Alignment LED

20. 20 (c) Tester Level for Fine Alignment 3.0500

21. 21 (5) IP55 (Ingress Protection Rate) IP 5 5 : Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact

22. 22 IP5 5 : Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects. *Test duration: at least 3 minutes *Water volume: 12.5 liters per minute *Pressure: 30 kN/m² at distance of 3m

23. 23 (6) Adjustable Beam Interruption Time It is 50 mSec to 700 mSec. It is selectable according to the application.

24. 24 (7) AGC (Auto Gain Control) Control the Alarm Level according to the receiving Beam Power. If the receiving Beam power reduced very much in a short time, it could make Alarm even if Beam power is not blocked 100%. It means the unit always keeps the suitable alarm level automatically. This clever NRTM is always watching the receiving beam power and changes the alarm level to keep stable operation.

25. 25 (8) Unique Knockout Structure It is not necessary to cut the cover for making the knockout hole. The base has the enough height to make the knockout hole for wiring. It keeps IP55 for any application.

26. 26 (9) Pole mount bracket This is used for the pole installation. Without this mount bracket, the chassis bends and it makes the installation difficult.

28. 28 (10) Heater (option) NRTM works down to – 25 °C. But for the stable operation under the cold temperature below – 10 °C, this heater is very useful as the it warm up the inside of unit. 2 pieces are one set.
