Electromechanical assemblies play a vital role in the operation of a wide range of devices. What are electromechanical assemblies? What are they for?
What is Electromechanical Assembly?
The term electromechanical assembly has a wide meaning. This term refers to assemblies that are made up of mechanical and electrical components.
The final application will determine the type of assembly. These assemblies, which are usually very complex, are only manufactured by highly skilled specialists who use detailed blueprints.
Electromechanical assemblies are commonly made using the following techniques:
- Surface mounting
- Soldering
- Through-hole mounting
- Circuit layout
The complexity of these assemblies requires that the technicians be extremely precise. The components are often small and delicate. Therefore, accuracy is crucial.
Types and Applications of Electromechanical Assembly
The components will be determined by the specific purpose of a electromechanical assembly. There are many common applications.
Switches and Sensors
Sensor assemblies and switch assemblies are common components of many control systems.
Sensors are used to convert external stimuli, such as heat, motion, or light, into electrical signals. Sensor assemblies typically include the following components:
- Sensing Elements – to detect external stimuli
- Transmitters to transfer data collected
- Connector heads– for connecting the transmitters with the sensor wires
- Housings to protect the sensors
Switches allow or stop current flow through a system. Switch assemblies are typically made up of:
- Contacts– for controlling the flow of electricity to and from the switch
- Switching Mechanism– used to control a device (often as a toggle or pushbutton).
- Wiring harness This is what holds the switch in position
Panel
The use of panels is a common setup for electromechanical assemblies. They make it easier to distribute electrical power between circuits. These are created by following the steps below:
- Correctly positioning components on the back panel
- Create holes through punching or sawing for the components
- Drill holes for mounting the hardware
- The panel is wired
DIN Rail
They are also called mounting assemblies, as they are used to mount different components in an electromechanical assembly. The subassemblies or components that are used determine the configuration of a DIN Rail.
Power Supply
The power supply generates electricity by converting a current into the voltage and format required for a single or multiple electric loads. These can be integrated into products or used as standalone devices.
The following components are standard in most power supplies:
- Transformer – To modify voltage as it is coming in
- Rectifier: Converts AC current to DC
- Filter – after rectifying, this filters out the DC output wavelets
- Regulator – reduces ripple voltages from the filter
- Housing – casing to protect components
Transformers are used to transfer energy between circuits. Transformers are used to convert voltages from one circuit to another.
Transformers are made up of the following standard components:
- Secondary and primary windings
- Laminated core
- Insulating materials
- Tanks and accessories that are specific to a particular application (such as cooling tubes, oil conservers, breathers, etc.).
Cable and Harness
These assemblies are composed of wires and cable and are used to transmit electrical signals or power. These assemblies are made up of:
- Wires and cable – for the transfer of signals or power
- Relays: To automatically switch on and off the power (for circuits with high amps).
- Fuses are used to protect products from power surges.
- Connectors are used to connect the wires and components of the device.
- Insulators: To protect the system in case any electrical components come into contact with each other, or something else.
- Tie – To secure the assembly to system
Common Application
Electromechanical assemblies are used in many types of electronic devices. These devices are used in many industries.
Aerospace
Electromechanical assemblies are used in many devices of the aerospace industry. These assemblies must be compact, precise, and reliable. These assemblies require a high level of quality control.
These are often custom-designed and include specific features. Examples include switch panels, power boxes, and lighted cockpit panels.
Military
These devices, like those in the aerospace industry, need to be compact, precise and allow for specific features. These devices must also be rugged enough to withstand the harsh environments they are exposed to.
Panel assemblies and cable harness assemblies are common examples of military products.
Automotive
Durability is one of the most important factors in automotive assemblies. All car owners want their parts to last for as long as they can.
They also need to be flexible enough to adapt to different system requirements. The most common types are switching mechanisms, speed sensor, temperature sensors and others.
Fire Protection
To maximize safety, it is important to have reliable systems in place. For systems such as smoke extraction fans, fire alarms and emergency lighting to work properly, they depend on reliable assemblies.
In many public and private places, such as schools and hospitals, these systems are used. Here, all systems must be more resistant to fire than in other applications.
Agriculture
Electromechanical assemblies are found in many agricultural machines, such as tractors and combines. Switches and sensors are common types, and are often designed to maximize efficiency.
Heavy Equipment
They must be robust, reliable and able to handle harsh environments.
Wire harnesses and cable assemblies are common assemblies.
