Pepperl+Fuchs Photoelectric Switch A Good Helper in Industrial Control okplazas.com Hot Brand in 2021

The P+F Pepperl+Fuchs photoelectric switch uses the shielding or reflection of the light beam by the detected object, and the gate circuit of the synchronous loop is used to detect the presence or absence of the object. For example, the working principle of the diffuse reflection photoelectric switch with background shielding function is realized by adjusting the optical angle of the transmitting sheet and the receiving sheet. The detection distance of the switch is adjusted to the surface of the object being detected, and the signal sent from behind the object is blocked. The high-resolution characteristics of laser diodes can be used to accurately and reliably detect tiny objects. For example, the diameter of the light spot can reach 0.1mm.

P+F Pepperl+Fuchs photoelectric switch sensor, which converts the change of light intensity between the transmitting end and the receiving end into the change of current to achieve the purpose of detection. Since the output circuit and input circuit of the photoelectric switch are electrically isolated (ie, electrical insulation), it can be used in many occasions. A new generation of photoelectric switch devices manufactured using integrated circuit technology and SMT surface mounting technology has intelligent functions such as delay, widening, external synchronization, anti-interference, high reliability, stable working area and self-diagnosis. According to the structure, the photoelectric switch can be divided into three types: the amplifier separated type, the amplifier built-in type and the power supply built-in type. According to the detection method, it can be divided into diffusion type, opposite beam type, mirror reflection type, slot type photoelectric switch and optical fiber type photoelectric switch. Such as: diffuse reflection photoelectric switch is when the switch emits light, the target produces diffuse reflection, the transmitter and receiver constitute a single standard component, when there is enough combined light to return to the receiver, the switch state changes, the typical value of the operating distance Up to 3 meters. The through-beam photoelectric switch is composed of a transmitter and a receiver. The two are separated from each other in structure. When the beam is interrupted, a switch signal change will occur. The typical way is that the photoelectric switches on the same axis can interact with each other. Separate up to 50 meters.
