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.
More Product Information
Metal detection sensors identify the presence of steel or other ferrous materials. They are used in automation, safety, and machinery applications where reliable detection of metal components is essential.
- Large switching capacity in a small footprint
- Switch up to 16 A current - highest in its class
- High breakdown voltage (1,000 V rms between open contacts)
- Ideal for applications such as high current/high power switching, AC line power switching, driving relays for industrial machinery, solenoid switching, and automotive engine control
- Fail-safe interrupt inputs that can detect a fault condition automatically open up relays to their default state
- 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.
The high frequency reed switch series is engineered for precision switching in RF and high-speed digital applications. These switches are optimized to handle signals from DC up to 7 GHz, making them ideal for use in telecommunications, computing, and advanced test equipment.
With nickel/iron leads offering high magnetic permeability, these reed switches deliver exceptional linearity across a broad frequency spectrum. Their compact form factor allows for high-density PCB mounting, and internal shielding ensures minimal electromagnetic interference, even in tightly stacked configurations.
These switches are commonly integrated into high-frequency reed relays for enhanced durability and performance.
