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.
