- TypeParameter
- Mounting Type
The "Mounting Type" in electronic components refers to the method used to attach or connect a component to a circuit board or other substrate, such as through-hole, surface-mount, or panel mount.
Chassis Mount, DIN Rail - MfrSiemens

- Contact Materials-
- CoilResistance-
- Base Product Number
"Base Product Number" (BPN) refers to the fundamental identifier assigned to a component by the manufacturer. This number is used to identify a specific product family or series of components that share common features, characteristics, or functionality. The BPN is usually part of a larger part number or order code that includes additional information, such as variations in packaging, tolerance, voltage ratings, and other specifications.

- Rated control supply voltage at AC 60 Hz0 - 0
- Voltage type for actuatingDC
- Rated control supply voltage at DC72 - 72
- Number of auxiliary contacts as normally closed contact2
- Series
In electronic components, the "Series" refers to a group of products that share similar characteristics, designs, or functionalities, often produced by the same manufacturer. These components within a series typically have common specifications but may vary in terms of voltage, power, or packaging to meet different application needs. The series name helps identify and differentiate between various product lines within a manufacturer's catalog.
SIRIUS - Operating Temperature
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
-25°C ~ 60°C - Termination Style
"Termination style" in electronic components refers to the method used to connect the component to a circuit board or other electronic devices. It determines how the component's leads or terminals are designed for soldering or mounting onto the circuit board. Common termination styles include through-hole, surface mount, and wire lead terminations.Through-hole components have leads that are inserted through holes in the circuit board and soldered on the other side. Surface mount components have flat terminals that are soldered directly onto the surface of the circuit board. Wire lead terminations involve attaching wires to the component for connection.The choice of termination style depends on factors such as the type of component, the manufacturing process, and the space available on the circuit board. Different termination styles offer various advantages in terms of ease of assembly, reliability, and space efficiency in electronic designs.
Screw Terminal - Interface
In electronic components, the term "Interface" refers to the point at which two different systems, devices, or components connect and interact with each other. It can involve physical connections such as ports, connectors, or cables, as well as communication protocols and standards that facilitate the exchange of data or signals between the connected entities. The interface serves as a bridge that enables seamless communication and interoperability between different parts of a system or between different systems altogether. Designing a reliable and efficient interface is crucial in ensuring proper functionality and performance of electronic components and systems.
No - Contact Form
A page on a website that allows users to communicate with the site owner. The page has fields for filling in name, address and type of comment. On most company websites, email and mailing addresses are also included; however, the contact form provides an immediate, convenient way for users to ask the company questions.
4PST-2NO/2NC (2 Form A, 2 Form B) - Operate Time
The time interval between the instant of the occurrence of a specified input condition to a system and the instant of completion of a specified operation.
100 ms - Coil Voltage
Coil voltage refers to the electrical potential difference that is applied across the coil of an electromechanical device, such as a relay or a solenoid. This voltage is essential for energizing the coil, creating a magnetic field that enables the device to perform its intended function, such as opening or closing contacts. The coil voltage is specified by the manufacturer and varies depending on the design and application of the component, commonly available in standard values like 5V, 12V, 24V, and others. Proper selection of coil voltage is crucial for optimal performance and longevity of the device.
72VDC - Switching Voltage
The maximum switching voltage of a relay is the maximum voltage that can be across the contacts whether the relay is open or closed. Operating a relay with high voltages present can cause arcing, and this in turn erodes the contacts and eventually degrades contact performance.
690VAC - Max - Release Time
In telecommunication, release time is the time interval for a circuit to respond when an enabling signal is discontinued
13 ms - Must Operate Voltage
Must Operate Voltage is the minimum voltage level at which an electronic component or device is guaranteed to function correctly. Below this threshold, the component may experience performance issues, erratic behavior, or complete failure to operate. It is a critical specification for ensuring reliable operation in various applications where voltage variations can occur.
57.6 VDC - Contact Rating (Current)
Contact Rating (Current) is a parameter used to specify the maximum current that an electronic component's contact can handle without causing damage or failure. It is typically expressed in amperes (A) and is crucial for ensuring the safe and reliable operation of the component within a circuit. Exceeding the specified contact rating can lead to overheating, arcing, or even permanent damage to the component. Therefore, it is important to carefully consider the contact rating when designing or selecting components for a circuit to prevent potential hazards and ensure optimal performance.
10 A - Coil Power
Coil Power in electronic components refers to the amount of power consumed by a coil or inductor when an electrical current passes through it. It is a measure of the energy dissipated as heat within the coil due to its resistance. The coil power is typically specified in watts and is important to consider when designing circuits to ensure that the coil can handle the power without overheating. Properly managing coil power is crucial for the overall performance and reliability of electronic systems.
4W - Must Release Voltage
Must Release Voltage is the minimum voltage level that an electronic component, such as a relay or circuit breaker, requires to safely disengage or reset its mechanical operation. This parameter ensures that the component can reliably return to a non-energized state when power is removed or when a control signal goes low. It is an important specification for ensuring proper operation and safety in electronic circuits where the component may be exposed to fluctuating voltages.
- - Features
In the context of electronic components, the term "Features" typically refers to the specific characteristics or functionalities that a particular component offers. These features can vary depending on the type of component and its intended use. For example, a microcontroller may have features such as built-in memory, analog-to-digital converters, and communication interfaces like UART or SPI.When evaluating electronic components, understanding their features is crucial in determining whether they meet the requirements of a particular project or application. Engineers and designers often look at features such as operating voltage, speed, power consumption, and communication protocols to ensure compatibility and optimal performance.In summary, the "Features" parameter in electronic components describes the unique attributes and capabilities that differentiate one component from another, helping users make informed decisions when selecting components for their electronic designs.
