Technical Guide

Photoelectric Sensors
Photoelectric Sensors detect photo-optical workpieces.
Displacement & Measurement Sensors
These Sensors can be used to measure distances and heights.
Proximity Sensors
Proximity Sensors to detect ferrous and non-ferrous metal objects
Photomicro Sensors
These Optical Sensors provide a compact, low-cost method to detect workpieces.
Rotary Encoders
Rotary Encoders are sensors that detect position and speed by converting rotational mechanical displacements into electrical signals and processing those signals.
Ultrasonic Sensors
Ultrasonic waves are used to enable stable detection of transparent objects, such as transparent films, glass bottles, plastic bottles, and plate glass, using Through-beam or Reflective Sensors.
Pressure Sensors
With Pressure Sensors, changes in pressure can be measured to confirm suction, verify mounting, manage source pressures, and test for leaking. Differential Pressure Flow Sensors are also available.
General Information
The need for safety components within safety-related control systems arises when devising basic principles to prevent mechanical accidents and attain safety in machines
Satety Light Curtain
Safety light curtains use blocked light to detect workers in hazardous machine areas and to stop machines before workers are injured
Safety Switches
Safety switches come in the form of safety door switches and safety limit switches
Emergency Stop Switches
An emergency stop switch is a switch which is attached to a machine to interrupt operation in the event of an emergency
Safety Application Controllers
The Safety Application Controller receives signals from a safety input device and controls whether the machine should be started or not
Safety Relays
Unlike other relays, safety relays ensure the safety function even if contacts are welded together because they have forcibly guided (linked) contacts (EN 50205)
Level Switches
Level Switches These devices 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
Basic Switches
A Basic Switch is a small switch with a very small contact gap and snap-action mechanism and with a contact structure that switches for a specified movement and specified force enclosed in a case with an actuator provided on the exterior of the case
Limit Switches
A Limit Switch is enclosed in a case to protect a built-in basic switch from external force, water, oil, gas, and dust. Limit Switches are made to be particularly suited for applications that require mechanical strength or environmental resistance
Push Buttons / Indicator Lamps
A Pushbutton Switch is a switch designed so that its contacts are opened and closed by depressing and releasing a pushbutton on the Switch in the direction of its axis
Thumbwheel Switches
A Thumbwheel Switch is a setting switch that converts the numeric value selected by turning a disk-shaped part on which numbers are written into a binary, decimal, hexadecimal, or other code using the combination of ON and OFF signals for multiple contact circuits and that outputs the resulting code.
Programmable Controllers
A programmable logic controller (PLC), or programmable controller is an industrial digital computer which has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, or robotic devices, or any activity that requires high reliability control and ease of programming and process fault diagnosis
Programmable Terminals
Programmable Terminals are easy-to-use HMIs that provide representational power, network compatibility, and powerful controller linking to support facility and machine production
Servo Motors and Servo Drives
A Servo drive is a special electronic amplifier used to power electric servomechanisms. A Servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration
Frequency Inverters
A frequency inverter changes output voltage frequency and magnitude to vary the speed, power, and torque of a connected induction motor to meet load conditions
General-purpose Relays
Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized
Solid-state Relays
A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals
Power Controllers
power control refers to the process of controlling the power of a transmitter to achieve better communication signal or overall quality of service. It is mainly used to control the transmitting power of a communication device to achieve better performance
Code Readers
Code Readers can read 2D codes or bar codes and are available in installed or hand-held models
RFID Systems
Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked
A timer is a control device that outputs a signal at a preset time after an input signal is received
The term counter is derived from the word count. It is fairly simple for people to count ten or twenty objects, but larger numbers make counting increasingly difficult. Counters outperform people when it comes to counting accurately
Cam Positioners
Cam Positioners detect angles of rotation by means of absolute encoders and give output signals according to the preset ON and OFF angles (Cam program)
Temperature Controllers
These Controllers receive sensor signals and control heaters or other devices to maintain a preset temperature. They can also be used for humidity, pressure, and flowrate control. OMRON also provides temperature and humidity sensors
Digital Panel Indicators
Digital Panel Indicators perform digital processing on or conversion and display of voltages, currents, other analog signals, and pulse signals. They can also compare input values to set values, transfer data, and perform other functions
Power Supplies
Commercial AC power distributed from power plants cannot be supplied directly to the ICs and other electronic components built into electronic devices in automated office and factory equipment without destroying the components due to the high voltage of commercial AC power. Devices called power supplies or regulated DC power supplies are therefore required to convert commercial AC power into regulated DC power to drive ICs and other electronic components
Motor Protective Relays
Protection equipment from low to high volage. Electric circuit and productive facilities can be protected from unusual state of over-current, earth fault, voltage-drop and phase interruption by monitoring main circuit status of power supply
Axial Fans
An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate
