Mfr refers to the component's producing company, whose brand and manufacturing processes directly impact the component's performance, consistency, and traceability, making it a key reference during selection.

Question 2

What is the Series

Accepted Answer

Series indicates a manufacturer’s organized range of components, often named with a common prefix or code, to streamline product selection and ensure compatibility across similar models.

Question 3

What is the Package

Accepted Answer

his term denotes the protective casing (often made of plastic, ceramic, or metal) that encapsulates an integrated circuit, determining its size, reliability, and suitability for different mounting technologies like through-hole or SMT.

Question 4

What is the Base Product Number

Accepted Answer

By using the Base Product Number, manufacturers and customers can efficiently communicate about component families without detailing every specification, streamlining the procurement process.

Question 5

What is the Actuator Material

Accepted Answer

Actuator Material refers to the primary substance or combination of substances used to construct the core moving or force-generating component in an electromechanical actuator.

Question 6

What is the Circuit

Accepted Answer

A circuit is a closed path formed by interconnected electrical components and conductors, used to transmit current, process signals, or distribute electrical energy.

Question 7

What is the Electrical Life

Accepted Answer

The number of complete mechanical actuation cycles a switch, relay, or connector can perform while maintaining specified electrical performance (e.g., contact resistance, insulation) under a defined load (voltage, current, type). It is a key reliability m

Question 8

What is the Product Status

Accepted Answer

Product Status indicates the commercial availability and production stage of the component, such as Active, Not for New Design (NRND), Obsolete, or Last Time Buy (LTB).

Question 9

What is the Voltage Rating - AC

Accepted Answer

This parameter specifies the maximum root-mean-square (RMS) alternating current voltage a component can safely withstand continuously across its terminals or insulation without risk of breakdown, performance degradation, or safety hazard. It is a critical

Question 10

What is the Voltage Rating - DC

Accepted Answer

It specifies the maximum direct current potential difference a component, device, or insulating material can continuously withstand without risk of performance degradation or failure. This absolute maximum rating, measured in volts (V DC), defines the upp

Question 11

What is the Switch Function

Accepted Answer

It defines the specific operation performed by a switch's contacts when its actuator is toggled, such as making, breaking, or transferring an electrical circuit. Common functions include SPST (single-pole, single-throw) for simple on/off, SPDT (single-pol

Question 12

What is the Operating Temperature

Accepted Answer

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 powe

Question 13

What is the Termination Style

Accepted Answer

This parameter specifies the physical form and connection method of a component's leads or contacts, such as through-hole, surface-mount, screw terminal, or quick-connect. It defines the required assembly process (e.g., soldering, clamping) and is critica

Question 14

What is the Illumination Type, Color

Accepted Answer

This parameter specifies the technology and chromaticity of an integrated light source. It defines the core emission principle (e.g., LED, incandescent, neon) and the dominant wavelength or color temperature (e.g., red, cool white, 2700K), which are criti

Question 15

What is the Illumination Voltage (Nominal)

Accepted Answer

This parameter specifies the standard operating voltage required to power the internal light source (e.g., an LED or incandescent bulb) within an illuminated component, such as a switch or indicator. It is the primary electrical design value for the illum

Question 16

What is the Illumination

Accepted Answer

The luminous flux incident on a surface per unit area, measured in lux (lx) or foot-candles (fc). It quantifies the amount of visible light reaching a target, which is critical for designing sensor systems (e.g., photoelectric, imaging), specifying displa

Question 17

What is the Bushing Thread

Accepted Answer

This specification defines the standardized thread geometry (e.g., nominal diameter, pitch, and thread form such as NPT, G, or M) on a cylindrical insulating sleeve or adapter designed to be mounted through a panel or chassis hole. Its core function is to

Question 18

What is the Actuator Length

Accepted Answer

This parameter specifies the total axial dimension of the actuator's main body or its core moving element (e.g., piston, plunger, or slider). It is a fundamental mechanical specification that determines the device's physical footprint, stroke length, and

Question 19

What is the Actuator Type

Accepted Answer

Actuator Type refers to the fundamental classification of a device that converts an input energy source into controlled mechanical motion. It is defined by its core operating principle, such as electric (solenoid, motor), pneumatic (cylinder), hydraulic (

Question 20

What is the Features

Accepted Answer

These are the additional, non-core capabilities or characteristics integrated into a component beyond its primary function. They enhance performance, reliability, or ease of use, such as built-in protection (thermal shutdown, overcurrent), enable/disable

Question 21

What is the Current Rating (Amps)

Accepted Answer

Specifies the maximum continuous current a conductor, connector, or component can safely carry without exceeding its thermal limits, thereby preventing overheating and ensuring long-term reliability. This ampere (A) rating is a fundamental parameter for s

Question 22

What is the Ingress Protection

Accepted Answer

A standardized rating system (IEC 60529) that classifies the degree of protection provided by an enclosure against the intrusion of solid objects (first digit) and liquids (second digit). It quantifies resistance to dust, accidental contact, and water ing

Question 23

What is the Mounting Type

Accepted Answer

Mounting Type refers to the standardized classification of the method by which an electronic component or module is physically secured and electrically connected to a printed circuit board, chassis, or panel. It defines how the component integrates into t

Question 24

What is the Panel Cutout Dimensions

Accepted Answer

Specifies the precise length and width of the rectangular or shaped opening required in a panel or enclosure to mount a component, such as a connector, switch, or display. These dimensions are critical for ensuring proper mechanical fit, alignment, and se
