IFM E21278 is a 1 mm pinhole mask designed for O6E and O6S photoelectric sensors. It narrows the sensing beam to support detection of small objects and precise sensing tasks. The compact stainless-steel construction provides stable mounting and reliable operation in industrial environments.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
Controlled Sensing Beam
E21278 uses a 1 mm pinhole to restrict the optical beam of compatible O6 photoelectric sensors. The reduced aperture helps concentrate the sensing area for applications involving smaller targets. This can improve detection precision where a standard beam is too broad. The accessory is intended for specialized through-beam sensing applications. It provides controlled optical detection.
Small Object Detection
The 1 mm pinhole design supports detection of relatively small objects within the specified sensing range. IFM specifies an application range of approximately 0.2 m for this mask. The smallest detectable object is approximately 0.4 mm under the specified configuration. The best small-object performance is achieved when masks are fitted to both transmitter and receiver. This makes it suitable for precision object detection. (turn2search1)
Durable Stainless Steel
The mask is manufactured from stainless steel 1.4310 / 301L. The material provides good rigidity and durability for industrial use. Its compact dimensions allow it to be integrated without significantly increasing the sensor installation footprint. The stainless-steel construction supports stable aperture geometry. This contributes to consistent sensing performance.
Simple Installation
E21278 is designed as an accessory for O6E and O6S sensors. Its compact mask configuration allows straightforward installation on compatible sensing arrangements. The accessory can be used when a more focused sensing area is required. It provides a simple way to adapt the sensor to specific detection requirements. This reduces the need for mechanical changes to the main sensor.
