The EF303SF.2 contact element is a high-performance and reliable component designed for control and safety in industrial applications. It combines robust construction with a compact design, ensuring top-notch precision and safety. With its glass-fiber-reinforced, self-extinguishing thermoplastic housing, the contact element is particularly durable and resilient.

This model offers both Normally Closed (NC) and Normally Open (NO) contacts with a forced opening mechanism and a contact opening width of 3 mm, enhancing safety in critical operations. Its high mechanical lifespan of at least 10 million switching cycles and a maximum switching frequency of 1,200/h make the EF303SF.2 suitable for continuous use in demanding environments.
