SICK Brand new Photoelectric switch Gtb6-n1211 Photoelectric Sensor

product description

Photoelectric switch is used in crop position detection, liquid level control, product counting, width discrimination, speed detection, fixed-length shear, hole identification, signal delay, automatic door sensing, color code detection, punch and shear machine and safety protection and many other fields. In addition, the use of infrared concealment, but also in banks, warehouses, stores, offices and other occasions as anti-theft warning.

specification

1. Limit values when operated in short-circuit protected network: max. 8 A.

2. May not exceed or fall below Uv tolerances.

3. Without load.

4. At Uv > 24 V, IA max. = 50 mA.

5. Signal transit time with resistive load.

6. With light/dark ratio 1:1.

7. A = VS connections reverse-polarity protected.

8. B = inputs and output reverse-polarity protected.

9. D = outputs overcurrent and short-circuit protected.

1. Quality shell

Green shell, safe non-toxic fine workmanship, long service life.

2. LED indicator light

Red LED indicator light is intuitive, economical and easy to operate.

3. Adjustable screw twist

+" adjustable far, "-" adjustable near
L: adjustable normally open, D: adjustable normally closed.

4. High-quality cables

Thick wire, easy to bend, pull resistance, better conductivity.

Note: background: conservation of photoelectric sensor test results only related to the detection distance, and has nothing to do with the surface color and reflective rate, can be applied to detect bright color background dark on the surface of the target body, due to the color of target detection and reflective rate is different, choose regular diffuse type sensor on many occasions not reliable detection.
