1. Know about different types of relays and their
application
Most complex electronic machinery cannot be operated effectively
without relays. Relays are electromagnetic switches responsible for
closing and opening circuit contacts within an electronic circuit. Relays
are of various types and are used for industrial and household purposes.
For industrial purposes, it is always advisable to buy relays and other
electronic components from trusted and reliable manufacturers. When it
comes to relays, Omron is the world leader, known for its best quality
and highly versatile range of relays. Express Technology Group is the
trusted Omron relays wholesale distributors from where you can order
all types of Omron relays at an unbeatable price. These relays are used
in automobiles, washing machines, medical equipment, tanks, aircraft,
and ships have relays in them.
What are the different types of relays?
Depending upon the type of machinery and application, relays are of
various types. Read on to find out about the different types of relays.
 Electromagnetic Relay – Electromagnetic relay is the most
frequently used relay in various pieces of machinery. It transforms
mechanical energy into electrical singles. Its main parts are coils,
magnetic cores, springs, contacts, and armatures.
 Latching Relay – A Latching relay has only one current pulse and
the relay remains the same till the time the pulse stops affecting it.
It also keeps control over the power consumption in a circuit.

2.  Thermal Relay – These types of relays stand second on the list of
frequently used relays. Thermal relays of two types are available
for household and industrial purposes in offline and online stores
like Express Technology Group. One of them provides excitation
in the form of heat and the other one does that in the form of
current.
 Reed Relay – Reed relays have a magnetic material made of a thin
steel plate called the contact, magnetic system, and spring all at
once. One end of the board is fixed and another one is backed by
conductive elements, it moves by getting affected due to the
external magnetic field.
 High Voltage Relay – Most modern electronic pieces of
machinery require insulation test systems and this is the primary
reason behind the demand for high voltage relays. High voltage
relays are of two types – one which is for all load current
components and others which are low-voltage and high-voltage,
between the contact and control coil.
 Time Relay – Popularly called ‘Delay Relays’, they increase the
stability of automatic control systems. It is used for improving the
functions of a system in the field of electronics and engineering.
 Voltage Relays – These are made especially for controlling
current levels to a pre-determined value. These relays measure the
level of execution in the system and are called measuring relays.
 Power Factor Relay - This relay is used when the altering current
increases or decreases in comparison to the pre-determined level.
Power factor relays are used as power factor correction in
electronic appliances.
 Solid State Relay – Designed especially for fast switching
applications, a solid state relay has a single epoxy resin molded
solid state module.
 Flash Relay – Also called the Flasher, this relay is used in lamps
with one signal and in parts of signal boards that have many valves
in them.

3.  Rotary Relay – Rotary relay or motor-driven relay moves ahead
of the armature and the contacts of the relay get replaced by
rotatory motion.
 Sequence Relay – Sequence relays are known by various names
including alternators, step relays, and triggers. These relays open
and close contacts in a pre-determined sequence by using a catch
mechanism.
 Microprocessor Relay – Microprocessor relays are attached to
small computers. These computers have similar features with the
external current and the voltage transformers.
 Polarized Relays – Polarized relays are the direct current
electromagnetic relay with an additional constant magnetic field
source. The armature of the relay is affected by this source.
 Frequency Relay – When the frequency in an electrical system is
increased then severe damage can be caused due to excess power.
To avoid this, frequency relays are used. Their main aim is to
prevent the power system from collapsing or getting permanently
damaged.
Conclusion
Relays are one of the vital electronic components which are used in
many appliances. They have various types whose applications are for
both, household purposes and industrial purposes. For industrial
purposes, buy relays from trusted electronic component manufacturers.
Omron can be an ideal choice for buying relays. The Express
Technology Group which are Omron relays wholesale suppliers can
provide the best quality relays at an affordable price.
