Sonnenschein electrical components Germany Sonnenschein model Sonnenschein price

Sonnenschein electrical components are switches controlled by electromagnets, that is, a combination of an electromagnet and a switch. When the electromagnet coil is energized, it generates electromagnetic attraction, causing the movable iron core to push or pull the switch contacts to close, thereby connecting the controlled circuit. Electromagnetic switches are widely used in various industries, most commonly as contactors in the industrial sector. An electromagnetic switch is the control switch on a starter motor and is one of the three major components of a starter motor (DC motor, transmission engagement mechanism, electromagnetic switch). Its working principle is that the coil generates electromagnetic attraction when energized, causing the movable iron core to move. This action, on one hand, pulls the transmission engagement mechanism to advance the starter pinion to mesh with the engine flywheel ring gear, and on the other hand, pushes the switch contacts to connect, allowing the DC motor to be energized and operate, thereby driving the engine to start.

Utilizing existing DIN rail terminal block frame screw connection technology and adding circuits composed of electronic components, optoelectronic transmission coupling is achieved. The core of automatic control requires that the control unit be reliably isolated from various sensors and actuators to avoid interference. Sanmenwan WUKG12 opto-isolated terminals can effectively perform this function, ensuring that field signals match the low voltage required by electronic control devices. They can also serve as interface components between peripheral equipment for process control and control, signal, and regulator devices, and are suitable for different voltage and power ranges. Opto-isolated terminals offer advantages such as low signal loss at the control end, high switching frequency, no mechanical contact bounce, wear-free switching, high insulation voltage, resistance to vibration, independence from mounting position, and long service life, leading to their widespread application in the field of automatic control.

A solid-state relay is a contactless electronic switch with isolation functionality. As there are no mechanical contact parts during the switching process, in addition to having the same functions as electromagnetic relays, solid-state relays feature logic circuit compatibility, resistance to vibration and mechanical shock, unrestricted installation position, good moisture-proof, mildew-proof, and corrosion-resistant performance, excellent performance in explosion-proofing and preventing ozone pollution, low input power, high sensitivity, low control power, good electromagnetic compatibility, low noise, and high operating frequency. With no mechanical parts inside and a fully sealed potting structure, solid-state relays offer advantages such as vibration resistance, corrosion resistance, long service life, and high reliability. AC solid-state relays adopt zero-crossing triggering technology, resulting in short switching times, making them suitable for higher frequency applications. Optical isolation is used between the input and output circuits, resulting in very low input power consumption. The output end has a protection circuit and strong load capacity.

Sonnenschein electrical component applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. According to the nature of the output quantity of photoelectric sensors, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent, which can be used to measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. Examples include illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters, and turbidimeters, photoelectric alarms for fire prevention, and automatic detection devices and instruments for checking the diameter, length, ellipticity, and surface roughness of machined parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are not only widely used in civil and industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (4) Converting the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "present" or "absent" electrical signals when exposed to light or no light. Photoelectric elements are used as switching photoelectric conversion elements. Examples include photoelectric input devices for electronic computers, switching temperature regulation devices, and digital photoelectric tachometers for speed measurement.
