Metal detection position sensors are designed to detect the presence or movement of ferrous materials such as steel bolts, gears, or plates. Available in reed switch or Hall effect configurations, these sensors offer flexible solutions for proximity and position sensing. Reed-based sensors provide simple, low-power operation, while Hall effect versions offer dynamic, solid-state performance with zero-speed detection and enhanced durability. Ideal for industrial automation, safety systems, and heavy equipment, these sensors are available in various mounting styles and electrical outputs to suit diverse application needs.
Ultra-Compact Reed Switches for Precision Electronics
The ultraminiature reed switch series offers some of the smallest magnetic switching solutions available, with glass body lengths starting at just 3.95 mm. These switches are engineered for precision and reliability in space-constrained environments, making them ideal for miniaturized electronics and high-density circuit designs.
Despite their compact size, these switches maintain strong electrical performance thanks to advanced contact materials and hermetically sealed construction. Their flat lead design supports automated assembly processes such as surface mounting and tape-and-reel packaging, enabling efficient integration into high-volume production lines.
Commonly used in semiconductor testing, medical devices, telecommunications, security systems, and automotive electronics, these switches provide dependable magnetic actuation in applications where size, sensitivity, and durability are critical.
- The BX2 Series of edge-lit backlights provides a highly diffuse source of illumination, packed within a thin and thermally efficient housing.
- The BX2 allows for configuration with polarization or collimation. A backlight configured with collimation is best suited for applications requiring a higher degree of edge clarity when imaging object silhouettes.
- This second edition of our edge-lit backlight series is more than twice as bright as previous BX and CX models.
- As with most planar backlight designs, this product is useful for edge detection, part location & orientation identification, presence & absence, hole detection and object gauging.
