Omron pushes the limits of presence detection, expanding existing product lines in proximity photoelectric, and fiber-optic sensing to include longer distance part presence, a wide variety of part detection and robustness in the harshest conditions to ensure your plant is running smoothly and consistently.

Omron's vast product family is growing to include smarter sensors that allow users to make the most of having I/O all over the plant with IO-Link, to provide real-time condition monitoring and make predictive maintenance a reality.

Creators of the proximity sensor

Omron created the first proximity sensor in 1960 and has been perfecting it since.

60 Years Experience

Omron has more than six decades of experience in the sensor business.

200+ million sold worldwide

Omron has sold 200 million proximity sensors, supporting automation in factories all over the world.

IP67G oil resistance: What's it to you?

In today's plants, cutting oil is everywhere, even in your sensors. When it gets there it causes sensors failure and downtime -- unless you have the right equipment.

Quick Answers

Definition

Proximity sensors is a term to summarize a category of sensors that detect an object's presence or absence without physically contacting the object.

Types of proximity sensors

Proximity sensors are typically split into inductive, capacitive or magnetic type proximity sensors, although inductive are the most common.

Where to use proximity sensors

Because proximity sensors detect based on their electrical interaction with the object their sensing, there are fewer effects on performance in dusty or dirty environments.

What are photoelectric sensors?

Photoelectric sensors detect objects or changes in surface conditions through a variety of optical properties.

How a photoelectric sensor works 

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 indicating whether an object is present or absent.

What is a fiber optic sensor

A fiber optic sensor is a type of photoelectric sensor that enables the detection of objects in narrow locations by transmitting and receiving light from a fiber amplifier through a fiber optic cable.
