Reliable Switching in a Small Footprint

The miniature reed switch series features compact, power-efficient magnetic switches with glass body lengths ranging from 9 to 14 mm. Designed for precision and versatility, these switches operate with no power consumption in their normally open state, making them ideal for energy-sensitive applications.

Available in a wide range of switching characteristics, including close differential, high current, mercury wetted, high-performance, and SPDT (changeover) configurations, this series supports diverse design requirements across industries. Their small footprint makes them especially valuable in miniaturized systems such as semiconductor testing equipment and medical devices, while also serving critical roles in telecommunications, security, automotive, appliances, and industrial automation.

• The DF241 is characterized as a Small Low Angle Dark Field ring light. 
• Precisely aimed LEDs provide a very low angle of incidence, radial illumination pattern. 
• A scratch on a sheet of glass is a good example of a defect that can be detected with a low-angle dark field illuminator. 
• With a light intensity of 24kLux at a working distance of ½” (12.5mm), the DF241 is perfect for imaging problems limited to a small field of view. 
• A 25mm field of view is standard with an optional field of view of 35mm. 
• Available in a range of wavelengths from UV to IR. 

*Engineered to provide comparable optical characteristics to our previous RL1360.

Exterior Bottle Mount Liquid Level Sensors offer a reliable and hygienic solution for monitoring fluid levels in sealed or transparent containers. These sensors attach externally, eliminating the need for direct contact with the fluid, ideal for applications where contamination, leakage, or internal access is a concern. With flexible integration options and compatibility across various container materials, they are well-suited for use in medical devices, laboratory equipment, food processing systems, and industrial fluid management. Their non-intrusive design ensures easy installation and maintenance while delivering consistent performance.

Key switch position sensors play a critical role in ensuring secure On/Off control for industrial and robotic systems.
