SME-8M-DS-24V-K-2, 5-OE electrical components refer to the aggregate of service equipment provided for a specific group of traffic sources, such as trunk lines, switching devices, and control systems. The fundamental subject of traffic theory is the relationship among traffic volume, call loss, and bundle capacity; therefore, the trunk bundle is an important basic concept in traffic theory. A traffic source is the object served by the trunk bundle, typically referring to user equipment; in a broader sense, the upstream equipment serves as the traffic source for the downstream equipment. In telephone communications, the traffic source is also called a call source. The number of service devices contained in the bundle is called the bundle capacity. Figure 1 is a schematic diagram of the trunk bundle. The capacity of this bundle is V, and it provides service to N V load sources. Any traffic source initiating a call can occupy an idle service device in the bundle.

SME-8M-DS-24V-K-2, 5-OE Electrical Component Characteristics

The static characteristics of a sensor refer to the relationship between the output and input quantities when the input signal is static. Since the input and output quantities are independent of time in this case, their relationship, i.e., the static characteristics of the sensor, can be described by an algebraic equation without time variables, or by a characteristic curve plotted with the input quantity as the abscissa and the corresponding output quantity as the ordinate. The main parameters characterizing the static characteristics of a sensor include: linearity, sensitivity, hysteresis, repeatability, drift, etc. (1) Linearity: Refers to the degree to which the actual relationship curve between the sensor output and input deviates from the fitted straight line. It is defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted straight line over the full scale range to the full-scale output value. (2) Sensitivity: Sensitivity is an important indicator of the static characteristics of a sensor. It is defined as the ratio of the increment in the output quantity to the corresponding increment in the input quantity that causes this increment. S is used to denote sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide when the input quantity changes from small to large (forward stroke) and from large to small (reverse stroke). For the same magnitude of input signal, the output signals for the forward and reverse strokes of the sensor are not equal; this difference is called the hysteresis error. (4) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curves obtained when the sensor input undergoes continuous multiple full-scale changes in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor output changes over time while the input remains constant. There are two causes of drift: one is the sensor's own structural parameters; the other is the surrounding environment (such as temperature, humidity, etc.). (6) Resolution: When the sensor input increases slowly from a non-zero value, an observable change in the output occurs after exceeding a certain increment; this input increment is called the sensor's resolution, i.e., the minimum input increment. (7) Threshold: When the sensor input increases slowly from zero, an observable change in the output occurs after reaching a certain value; this input value is called the sensor's threshold voltage.

SME-8M-DS-24V-K-2, 5-OE Electrical Component Functions

The starter solenoid switch is a key component of the starter motor, and its design quality directly affects the reliability of the starter. The starter solenoid switch has two functions: first, to connect the main circuit to rotate the starter motor; second, to push the drive gear out via the shift fork to engage with the engine flywheel ring gear. Therefore, the solenoid switch is required to have appropriate attraction force, appropriate stroke, and contacts capable of reliably switching high currents. Additionally, it is required to minimize volume and weight as much as possible. Based on these characteristics, the contact structure of the solenoid switch generally adopts a contact form, i.e., the moving contact is made into a bridge shape or disc shape to provide a larger heat dissipation surface and thermal capacity. The magnetic system mostly adopts a solenoid electromagnet structure to meet the requirements of appropriate stroke, appropriate attraction force, small volume, and light weight. The moving iron core of the solenoid switch can move smoothly within the brass bushing equipped with the solenoid coil. The moving iron core pull rod is connected to the one-way clutch via the shift fork. Under the action of the return spring, the moving iron core normally remains in the initial non-operating position. During starting, the starter drive gear needs to move forward by approximately 12-29mm. Therefore, when the solenoid switch begins to engage, a large magnetomotive force is required to generate the necessary initial attraction force. After engagement, the air gap decreases, and the electromagnetic attraction force increases sharply, greatly exceeding the force required to maintain the engaged state. For this reason, the solenoid switch employs two coils (the pull-in coil and the holding coil). Initially, both the pull-in coil and the holding coil jointly generate electromagnetic attraction. After the switch contacts close, the pull-in coil automatically disengages from operation, and only the holding coil maintains the switch in the engaged state. The holding coil current is relatively small, allowing it to be wound with thinner wire. This reduces the volume of the solenoid switch while achieving reasonable attraction force matching. To ensure the reliability of the starter motor, emphasis must be placed on controlling the design quality of the solenoid switch.

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It consists of two or more thermocouples connected in series, with the thermoelectric potentials output by each thermocouple superimposing on each other. It is used to measure small temperature differences or average temperatures. Structure of a thermopile: The radiation receiving surface is divided into several sections, each connected to a thermocouple. Connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made into wire-type and thin-film types, as well as multi-channel and array-type devices.
