Overview

The role and function of OPTEX photoelectric sensors are to align the transmitter with the target and emit a beam of light. The emitted beam generally comes from semiconductor light sources, light emitting diodes (LEDs), laser diodes, and infrared emitting diodes. The beam is emitted continuously or the pulse width is changed. The receiver consists of photodiodes, phototransistors, and photovoltaic cells. In front of the receiver, there are optical components such as lenses and apertures. Behind it is the detection circuit, which can filter out effective signals and apply them.

The function and function of OPTEX photoelectric sensor

The 11BGS background suppression sensor can be used to detect any object, unaffected by object color or background color.

The cable is tightly connected to the internal circuit board and can withstand a tensile force of 70N (7KG).

Quick and easy disassembly, convenient maintenance. Simply remove the body from the base for replacement.

The shooting type V3T/V4T-7000 has a detection distance of up to 70m.

Terminal connection (V4 series AC type).

In addition to the function of converting light signals into electrical signals through photodiodes, phototransistors also have the function of amplifying electrical signals. The appearance of a photosensitive transistor is not much different from that of a general transistor. Generally, a photosensitive transistor only has two poles - the emitter and collector - and the base is not led out. The tube shell is also opened with a window for light to enter. To increase the illumination, the base area is made large, the emission area is small, and the incident light is mainly absorbed by the base area. During operation, the collector junction is reverse biased and the emitter junction is forward biased. The current flowing through the transistor in the absence of light is the dark current Iceo=(1+β) Icbo (very small), which is smaller than the penetration current of a typical transistor; When illuminated, a large number of electron hole pairs are excited, causing an increase in the current Ib generated at the base. The current flowing through the transistor at this moment is called photocurrent, and the emitter current Ie=(1+β) Ib. It can be seen that phototransistors have higher sensitivity than photodiodes.

The DM-18T series is an RGB three color light source color code sensor.

Both plastic and metal casings comply with RoHS standards. The electrical design aims for ecological energy conservation, with a product current consumption of only 18mA (diffuse reflection type).

The difference in hysteresis phenomenon between black and white objects is 10% (diffuse reflection type). When the object is white, the detection distance of C2DM-11 is 110mm, and when the object is black, the detection distance is 90mm.

The sensitivity adjustment potentiometer has a tight waterproof function and a protection level of IP67. It has functions such as waterproofing, oil resistance, chemical resistance, and high temperature resistance.

The sensing area of the product is relatively large, so the calibration of the reflective sensor is relatively simple during installation. For example, a detection distance of 10m allows for a 70cm area for calibration. High power LED lights can achieve long-distance visibility.

In addition to using nickel plated brass material, the outer shell of metal products is also wrapped with a layer of 20um thick nickel plating on the inner and outer surfaces, which makes the metal shell more tough and effectively prevents rusting.
