Metal Tactile Switches Type of package
Touch the switch
Touch switch, use the button when you gently press the switch button can be turned on, when the release of the hand when the switch is broken, the internal structure of the metal shrapnel by force to achieve on-off. Such as the IKI series of touch buttons.
Touching switch due to the small size of light in the electrical aspects of a wide range of applications such as: audio and video products, digital products, remote control, communications products, household appliances, security products, toys, computer products, medical equipment, car keys and so on.
1, SMT patch;
2, DIP plugin.
Specifications: 6x6mm, 12x12mm, 5x5mm, 3x6mm
Touch the main technical parameters of the switch
1, environmental standards: RoHS, halogen-free, as well as the EU and other areas of the limits of the control of hazardous substances.
2, rated current, voltage: usually mA level, 50mA 12VDC.
3, the operation intensity: 50gf, 100gf, 160gf, 260gf, 320gf, 520gf.
4, the operating life: the operating life is generally inversely proportional to the intensity of operation,
Take 160gf, usually 6x6 switch can be done 100 million times to 300 million times the life.
5, the working environment temperature: -25 degrees Celsius to +70 degrees Celsius
6, the switch stroke: 0.25mm
Photoelectric switch is a member of the sensor family, it changes the intensity of light between the transmitter and the receiver into a change in current to achieve the purpose of detection. Since the photoelectric switch output circuit and the input circuit are galvanically isolated (ie, the capacitor must be), so it can be applied in many occasions.
The use of integrated circuit technology and SMT surface mount technology and manufacturing a new generation of photoelectric switch devices, with delay, broadening, external synchronization, anti-interference, high reliability, work area stability and self-diagnosis and other intelligent functions. This kind of novel photoelectric switch is a kind of active type photoelectric detection system type electronic switch which adopts pulse modulation. It uses cold light source with infrared light, red light, green light and blue light. It can be non-contact, And control the various solid, liquid, transparent body, black body, soft body and smoke and other substances in the state and action. The contact stroke switch has the advantages of low response speed, poor precision, easy detection of contact detection and short life expectancy, and the short distance of the transistor proximity switch can not directly detect non-metallic materials. However, the new photoelectric switch is to overcome their shortcomings, and small size, multi-function, long life, high precision, fast response, detection distance and anti-light, electricity, magnetic interference ability.
This new type of photoelectric switch has been used for level detection, level control, product counting, width discrimination, speed detection, fixed length cutting, hole identification, signal delay, automatic door sensor, color detection, punch and Cutting machines and security protection, and many other areas. In addition, the use of infrared hidden, but also in the banks, warehouses, shops, offices and other needs of the occasion as an anti-theft alert.
