Standex Detect - Intrinsically Safe Relays
Intrinsically safe reed relays and optocouplers are engineered for use in hazardous environments where ignition prevention is critical. Certified to ATEX standards and tested to ensure they do not become ignition sources, even in the presence of short circuits or adjacent component failures—these components are ideal for applications in explosive atmospheres such as mining, chemical processing, refineries, and power stations.
Designed to meet EN50020 safety standards, these relays and optocouplers feature tightly controlled air and creepage paths, high dielectric strength, and low-voltage coil inputs. With a maximum peak voltage of 375 V across input and output, and isolation distances up to 10 mm, they ensure safe operation under overload conditions. The Comparative Tracking Index (CTI) of the plastics used exceeds 175, and internal potting compounds provide additional insulation for long-term reliability.

- 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.
- High Intensity: up to 9x brighter than the existing SL191 Pattern Projecting Spot Light and more than 3x brighter than the leading competitive structured light projector.
- Projection patterns are easily configured with available reticles, including line, grid, cross, multiple lines, and half sphere, with custom reticles available.
- Customizable: available in multiple wavelengths, including white.
- Constructed with a large heat sink for improved LED thermal management to facilitate increased brightness while maintaining safe operating temperatures.
- Ideal solution for machine vision inspection applications requiring structured illumination, including edge detection, locating offsets, and assessing topography.
- Requires a reticle and lens (sold separately); see available reticles here.
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.
