Frequently Asked Questions (FAQs)

What are the three types of photoelectric sensors?

There are six types of photoelectric sensors including through-beam sensors. retro-reflective sensors, diffuse-reflective sensors, mark sensors, and distance-settable sensors. Each sensor has its own strength.

How does photoelectric sensor work?

Photoelectric Sensors detect objects, changes in surface conditions, and other items through a variety of optical properties. A Photoelectric Sensor consists primarily of an Emitter for emitting light and a Receiver for receiving light. When emitted light is interrupted or reflected by the sensing object, it changes the amount of light that arrives at the Receiver. The Receiver detects this change and converts it to an electrical output. The light source for the majority of Photoelectric Sensors is infrared or visible light (generally red, or green/blue for identifying colors).

What is Omron sensor?

OMRON Sensing Components detect, measure, analyze, and process various changes that occur on productions sites, such as changes in position, length, height, displacement, and appearance. They also contribute to predicting and preventing future events.

What can a proximity sensor detect?

Proximity Sensors are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. Models are available with environment resistance, heat resistance, resistance to chemicals, and resistance to water.

What are level switches?

Level Switches equip electrodes to detect liquid levels. They have been widely used in water works and sewers for buildings and housing complexes, industrial facilities and equipment, water treatment plants and sewage treatment facilities, and many other applications.

What does a programmable controller do?

  • A programmable controller (PLC) has a microprocessor and controls devices through custom user programs.
  • A PLC receives signals from input devices and makes decisions based on custom programs to control output devices.
  • Ladder logic is a graphical programming language and is commonly used for PLC programming. Programming software, such as CX-Programmer, is used for programming on a PC.

What are the types of power supply?

Omron provides many types of general-purpose Power Supplies, such as the type mounted to DIN rail or the type built into equipment. OMRON also provides the S8VS which provides notification of replacement timing, and the Buffer Block that handles momentary power interruptions, and other highly reliable Power Supplies.
