In the electronics industry, optimizing products and processes is at the heart of the smart solutions of the future. The end product will be smaller, flatter and lighter, expanding its performance in a completely new size. The more streamlined automation solutions become, the more they can realize their optimization potential for quality and cost savings. Inspection requirements increase with industrial complexity.
SICK offers the answer:
The technology for every challenge is packed in an ultra-compact housing.
In the electronics industry, the complex optical properties of the object to be inspected will bring difficulties to detection, such as black, small, porosity, transparency, shiny, etc. Photoelectric sensors from SICK, on the other hand, rely on a number of factors to reliably detect a wide range of objects.
Technology makes a difference
The red laser light source is the key to reliable detection from SICK. Tiny laser beams are an ideal starting point for detecting objects and their features, no matter how small they are.
The small light spot greatly improves the accuracy of the switching output, thus laying the foundation for optimizing product quality, while also reducing switching malfunctions and improving the usability of the machine.
When conventional red light sources reach their limits, SICK uses blue light instead. For example, the WTB2S-2 (blue light) miniature photoelectric sensor can perfectly detect ultra-light-absorbing objects, such as deep blue solar wafers.
At the same time, if you want to identify the deepest blacks, PinPoint 2.0 LED technology is ideal. Compared to the first generation of PinPoint LEDs, the amount of light emitted is more than twice as high.
The new generation of sensors from the W2S-2 series not only "sees" ultra-black colors, but also ensures reliable detection of any type of object, for example in the housing of battery cells or modules in the smartphone industry. They have the advantage of "providing the best performance in an ultra-compact design".
The WT2-S sensor has a V-shaped lens that reliably detects flat, highly transparent or reflective objects, such as monitors or smartphone screens.
Tailored
Detection must adapt to changing needs: The rapid development of the electronics industry has set new rhythms and standards, challenging sensors from the point of view of optimizing production and costs.
When it comes to shorter investment cycles, smaller objects, and small and intelligent automation solutions, the right sensor technology is always the best response. This is directly reflected in sensor solutions – for example, different technologies can be combined in the same platform.
With the W4 miniature photoelectric sensor, the UC4 ultrasonic sensor, and the CQ4 capacitive proximity sensor, SICK has created such a technology platform – and packaged the solution into a sugarcube-sized housing.
Micro trio: W4, UC4, and CQ4
The compact design makes it easy to design the sensor into the machine. As a result, the sensors can be used flexibly even under difficult installation conditions.
These sensors have proven their high detection capability by offering a wide range of detection properties and full mechanical compatibility, thus opening up many potential applications in the electronics industry.
The CQ4 capacitive proximity sensor can be used to inspect light-absorbing wafers in the electronics and solar industries, while the UC4 relies on ultrasonic technology to identify dark, shiny, and even very fast objects. MultiLine is a high-end member of the W4 family of miniature photoelectric sensors that, thanks to its two-line light source, can detect PCBs very reliably and therefore sit side by side with the best in its class: the WTV4-3 has high-precision inspection of v-optics, two-line light source, infrared LED and Pin-Point LED porous PCBs.
The WTV4-3 is a diffuse photoelectric sensor with a two-line light source that enables easy inspection of printed circuit boards with holes
Smart Detection: In the open
network
If photoelectric sensors from SICK fill the gap in the small, IO-Link bridges the gap in the big way.
As a bridge to the lowest field level and a link between all process participants, IO-Link is fully transparent – opening up a new dimension of real information for the acquisition of machines.
The role of sensors is being redefined thanks to the traceability of production data and the preventive diagnosis of errors and conditions, and also paves the way for intelligent sensing technology in the context of Industry 4.0.
In the newly developed SIRIC®ASIC technology, you can learn about intelligent sensing technology from SICK. Photoelectric sensors with this optical technology can be seamlessly connected into automation networks as smart sensor solutions.
In addition to diagnostics and remote setting functions, they also take on various automation functions such as counting functions, time measurement, remote interference suppression or positioning functions via "time stamping", all of which will reduce the burden on the control level and increase the productivity of the machine. Even with the rapid development of sensing technology, the form factor of the smart sensor will remain the same: the smart sensor in an ultra-compact housing.
Reliable edge detection with ultrasonic technology
The complete range of performance within the same product family
Recently, SICK's miniaturization strategy has taken it to the next level: the PowerProx Small, a multi-task photoelectric sensor that combines all the advantages of time-of-flight technology in the world's smallest housing and a large scanning range.
Here, six different sensors are designed for a wide range of inspection tasks and can be used in a wide range of applications, even in automated environments for robot-assisted production.
The presence check of objects presents highly dynamic challenges. Therefore, the sensors mounted on the gripper must be as small and lightweight as possible. With its miniature dimensions, 800 mm scanning range and possible smart sensor capabilities, the PowerProx Small offers innovative solutions for the core tasks of the industry of the future in this context.

How Sick sensors work
SICK sensors are sensors that use a photoelectric element as a detection element. It first converts the measured change into a change in the optical signal, and then further converts the optical signal into an electrical signal with the help of an optoelectronic component. Photoelectric sensors are generally composed of three parts: light source, optical path and optoelectronic components.
