IFM E21281 is a 1 × 8 mm slot mask designed for O6E and O6S photoelectric sensors. It narrows the sensing area to support precise detection of small objects. The compact stainless-steel construction provides stable mounting and reliable performance in industrial automation applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
Controlled Optical Aperture
E21281 features a 1 × 8 mm slit diaphragm designed to control the sensing beam of compatible O6 sensors. The elongated aperture provides a defined sensing zone for specialized detection applications. It can be used when a standard sensing beam needs to be restricted. This supports more controlled photoelectric detection. The accessory is particularly useful for precision sensing tasks.
Small Object Detection
The slot mask supports detection of small objects within an application range of approximately 1.5 m. The smallest detectable object is approximately 0.5 mm under the specified conditions. The accessory is designed for O6E and O6S sensor types. For the smallest detection capability, suitable masks should be attached to both transmitter and receiver. (turn1search0) This makes it useful for detailed object detection.
Compact Stainless Steel Body
The mask uses stainless steel 1.4310 / 301 material for reliable mechanical performance. Its dimensions are approximately 33.5 × 12.5 × 2.8 mm. The rigid construction helps maintain the slit opening during continuous operation. The material provides good resistance to normal industrial handling. Its compact size makes installation convenient.
Easy Sensor Modification
E21281 provides a simple method of modifying the sensing characteristics of compatible photoelectric sensors. It can be installed as an accessory without changing the main sensor body. The mask helps create a more defined sensing zone. This can improve suitability for specialized machine detection tasks. It provides a practical accessory for industrial sensor optimization.
