Product Description

The Omron Compact Photoelectric Sensor with Built-in Amplifier is designed for precise and reliable object detection in industrial applications. This square-type sensor features a sensing distance of 20 to 200 mm with a red LED light source for accurate detection. The sensor is equipped with a PNP open collector output and comes in a pre-wired model for easy installation.

With its distance-setting sensing method, the sensor ensures high accuracy and stability, making it ideal for various automation tasks. The sensor includes protective circuits such as output short-circuit protection and power supply reverse polarity protection, ensuring safe and reliable operation. The operation mode is selectable between Light-ON and Dark-ON, providing flexibility for different application requirements.

Built to withstand harsh environments, the sensor offers IP67 protection and can operate in a wide temperature range from -25 to 55°C. It also features high resistance to vibration and shock, ensuring durability and long-term performance. The sensor is equipped with an operation indicator (orange) and a stability indicator (green) for easy status monitoring.
