Klaus Poetter electrical components Germany Klaus Poetter models Klaus Poetter prices

Klaus Poetter electrical components are pyroelectric infrared sensors, devices constructed from thermocouples. They are widely used as temperature detection devices in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature monitoring. The entry details the basic unit of a thermopile—the thermocouple—and provides a detailed introduction to the structure, working principle, main parameters, and applications of thermopiles.

Klaus Poetter electrical components principle

When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, equivalent to a resistor with infinite resistance. In other words, when the voltage applied across it is below its threshold, it acts like an open switch. When the voltage applied to the varistor exceeds its threshold, the current flowing through it surges, equivalent to a resistor with near-zero resistance. In other words, when the voltage applied across it is above its threshold, it acts like a closed switch. Protection principle of surge absorbers: In the standby state, the varistor has very high impedance (several megaohms) relative to the protected electronic components and does not affect the characteristics of the original circuit design. However, when an instantaneous surge voltage occurs (exceeding the breakdown voltage of the surge absorber), the impedance of the surge absorber drops low (only a few ohms), causing a short circuit in the line, thereby protecting electronic products or more expensive components.

Klaus Poetter electrical components classification

Classification by operating principle or structural features of relays: (1) Electromagnetic relay: An electrical relay that operates using the attractive force generated between the electromagnet core and the armature by the current in the input circuit. (2) Solid-state relay: A relay with input-output isolation where electronic components perform functions without mechanical moving parts. (3) Temperature relay: A relay that activates when the ambient temperature reaches a set value. (4) Reed relay: A relay that opens, closes, or switches circuits using the action of reed contacts sealed in a tube, which serve both as contact springs and part of the magnetic circuit with the armature. (5) Time-delay relay: A relay whose output section delays or limits operation to a specified time before closing or opening the controlled circuit when an input signal is applied or removed. (6) High-frequency relay: A relay used for switching high-frequency and RF lines with minimal loss. (7) Polarized relay: A relay that operates due to the combined effect of a polarizing magnetic field and the magnetic field generated by the control current passing through the control coil. The direction of relay operation depends on the direction of the current flowing through the control coil. (8) Other types of relays: Such as optical relays, acoustic relays, thermal relays, instrument-style relays, Hall effect relays, differential relays, etc.

Klaus Poetter electrical components principle

Inductance is the ratio of the magnetic flux in and around a conductor to the current producing this flux when alternating current passes through the conductor. When direct current passes through an inductor, only static magnetic field lines appear around it, unchanged over time; however, when alternating current passes through a coil, time-varying magnetic field lines appear around it. Analyzing according to Faraday's law of electromagnetic induction—magnetism generating electricity—changing magnetic field lines produce an induced electromotive force (EMF) at the ends of the coil, which acts as a "new power source." When a closed loop is formed, this induced EMF generates an induced current. According to Lenz's law, the total magnetic flux produced by the induced current attempts to oppose the change in the original magnetic flux. Since the change in the original magnetic flux originates from changes in the external AC power source, objectively, the inductive coil has the characteristic of opposing changes in current in an AC circuit. Inductive coils have properties similar to inertia in mechanics, termed "self-induction" in electrical engineering. Sparks often occur at the instant of opening or closing a knife switch, caused by the high induced EMF generated by self-induction.
