Design man-hour reduction! Handa DIP ultra-small reflective photo sensor KR3140

Design man-hour reduction! Handa DIP ultra-small reflective photo sensor KR3140

Despite being ultra-compact, it has a long focal length and is user-friendly for designers—an infrared photo reflector! It also supports flow solder mounting.

The "ultra-compact photo reflector KR3140," packaged in dimensions of 3.0mm (height) x 4.0mm (width) x 2.4mm (depth), not only contributes to the lightweight and compact design of the mounting board but also extends the focal length to 3mm, six times longer than our conventional product (KR3930, d=0.5mm), making mechanical design easier. Additionally, it employs a visible light-cut resin that is resistant to stray light, allowing it to be used even at the edges of the housing while functioning as a light sensor.

Value Up through a Shift in Thinking! A Collection of Case Studies on Problem Solving with Photo Sensors

Value Up through a Shift in Thinking! A Collection of Case Studies on Problem Solving with Photo Sensors

Examples are provided that demonstrate the realization of weight reduction and cost reduction by narrowing down functionalities and utilizing photo sensors as alternatives to liquid level sensors and CCDs.

At Shinko Electronics, we have been developing, manufacturing, and selling photo sensors for over 40 years. We offer a wide range of photo sensors that excel in various fields, including transmission type, reflection type, separation type, prism type, and actuator type, and we can customize them to meet your specific needs. Laser sensors, electrode-type sensors, float-type liquid level sensors, motion sensors, FA sensors... Various sensors are used in both industrial and consumer devices. However, by identifying the purpose of detection and rethinking the approach, it is sometimes possible to meet functionality with standard photo sensors. If you have concerns about the size, weight, or price of the sensors you are using, please feel free to contact us. Our knowledgeable sales representatives will propose alternative photo sensors that can meet your needs. = Case Study Contents = ■ Detection of full tank in portable device drainage tanks - Successfully achieved a weight reduction of 95% by replacing with an electrode-type level sensor ■ Detecting thin line dragonfly marks - Successfully detected dragonfly marks as small as 0.3mm at a low cost * The case studies also include product data sheets. Please feel free to reach out for inquiries.

Liquid Detection Photo Sensor KB3390 and Other New Product Introduction Leaflet

Liquid Detection Photo Sensor KB3390 and Other New Product Introduction Leaflet

No need for expensive liquid detection sensors! A general-purpose photo sensor can detect the presence or absence of liquid passing through pipes or tubes.

○ Expensive liquid detection sensors are not necessary. General-purpose photo sensors can detect the presence of liquid passing through pipes or tubes. ○ Increasing added value through a change in perspective. Liquid detection is not possible with conventional installation methods. By changing the perspective and adjusting the position, we utilized the refractive properties of light to enable liquid detection. ○ In addition to separated photo sensors, there are sensors that can detect liquid using general-purpose photo interrupters as well.
