The R2 and R3 series of photoelectric sensors are impressive products that characterize a very small housing plan. Robust R2/R3 miniature photoelectric sensors – the space-saving R2/R3 series of photoelectric sensors in miniature housings, which are smaller than matchboxes
The standard photoelectric sensors R2 and R3 impress with their extremely small housing design. The ultra-compact R2 series has an M2 device hole for complete space saving, and the R3 series is supplied with a standard M3 device hole. Due to their miniature housing design, photoelectric sensors are used for high-precision detection in small spaces with high ambitions.
Maximizing the freedom of the equipment, 45° cable outlet maximizing the flexibility of the equipment!
When using a very small photoelectric sensor, the equipment and space for use are often limited. Therefore, the flexibility of any kind of equipment often assists in the right and wrong. The two standard photoelectric sensor series offer flexibility via a 45° cable outlet. Combined with the right device bracket, the right and wrong of the device in the smallest of spaces is often simplified. In addition, these device mounts are suitable for all sensing methods.
Thanks to the anti-static front glass, the downtime of the machine is improved and the availability of the machine is increased!
In some applications, where close proximity is required to inspect substrates, such as paper mesh machines, the vibration energy can cause wear and tear on the sensor surface. In this way, the sensor is quickly "blinded" and the requirement is replaced. The R2 and R3 photoelectric sensors are equipped with a wear-resistant, anti-static front glass. The front glass avoids dust accumulation and wear, resulting in better machine availability and increased machine availability.
A variety of sensing methods are suitable for all types of applications
The R2 and R3 series of extremely small photoelectric sensors are primarily designed for use in tight spaces. Extremely small, concentrated light spots, scratch-resistant front glass, and a variety of sensing methods can be used as new application solutions.
Typical applications are as follows:
Detection of the presence or absence of objects
Small parts inspection
Leading-edge (marginal) trigger detection
Counting, such as disc feeders
Compact and robust - the R2 / R3 miniature photoelectric sensors
At that time, small-sized photoelectric sensors covered almost all shopping malls for packaging work, logistics work, printing work, and electronic work routine sensors. R2/R3 series miniature photoelectric sensor has become the best product of new equipment, and its ultra-high performance, mini appearance, and moderate price will become the new favorite of electronics, logistics, printing and other work... Safety Integrity Level (SIL) Introduction:
SIL is an abbreviation for Safety Integrity Level. Safety integrity is the probability that the safety-related system will successfully complete the required safety functions under the rule conditions and at the time of the rule. Security integrity consists of hardware security integrity and system security integrity. The SIL level is based on the effectiveness of the risk assessment.
Application of inclination sensor in fire truck:
With the acceleration of urban modernization and the increase of urban population, urban land resources are becoming more and more scarce. In order to cope with this problem, both residential and commercial residences are initially launched to the sky, and high-rise residences appear everywhere in the country, and this trend will continue consistently.
Introduction of sensors with safety functions:
Sensors with safety functions, such as proximity switches, are the same as NAMUR proximity switches, but have a special function: in the event of a sensor malfunction, the output of the controller automatically switches to a safe "off" state if the control unit or the universal connection cable fails. This series of sensor tests is based on IEC61508 and lists relevant data such as the probability of a defect and the percentage of defect safety. In the SIL section of the product list, you can find information about the SIL for each sensor in the circuit.
