NbMAX Spring Terminal Blocks

The photoelectric switch (photoelectric sensor) is the abbreviation of the photoelectric proximity switch, which 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. The object is not limited to metal, all objects that can reflect light can be detected. The photoelectric switch converts the input current into a light signal on the transmitter, and then the KE receiver detects the target object according to the intensity or presence of the received light. The common photoelectric switch smoke alarm in the security system is often used in the industry to count the movement times of the robotic arm.

Features of photoelectric switch
The MGK series photoelectric switch is the product of the development of modern microelectronics  wholesale waterproof connectors technology, and is an upgraded product of the HGK series infrared photoelectric switch. Compared with the previous photoelectric switches, it has its own remarkable characteristics: 　

●With self-diagnosis and stable working area indication function, it can inform in time whether the working status is reliable;
●The through-beam, reflective, and mirror-reflective photoelectric switches all have the function of preventing mutual interference and are easy to install;
●The setting of ES external synchronization (external diagnosis) control terminal can pre-check whether the photoelectric switch is working normally before running. It can accept interruption or detection instructions from the computer or programmable controller at any time. The appropriate combination of external diagnosis and self-diagnosis can make the photoelectric switch intelligent;
●Fast response speed, the response speed of the KE dial switch high-speed photoelectric switch can reach 0.1ms, and it can perform 300,000 detection operations per minute, which can detect small objects moving at high speed;
●Using ASIC and advanced SMT surface mounting technology, it has high reliability;
●Small size (minimum only 20×31×12mm), light weight, simple installation and debugging, and has a short circuit protection function.
