The Pilz PIT ES SET3S-5 S (Part Number: 400449) is a high-quality control and signal device engineered to provide dependable emergency stop functionality in industrial safety applications. Part of the well-established PIT ES product line, it combines durability, flexibility, and compliance with safety standards to ensure reliable shutdown of machinery in critical situations.

Operating within a supply voltage range of 12–30 V AC/DC, the device is highly adaptable to diverse industrial control setups. This wide voltage tolerance makes it equally suitable for integration into both modern DC-based systems and traditional AC installations. For engineers and system designers, this flexibility reduces the need for additional adapters or converters, simplifying integration and reducing overall system complexity.

The PIT ES SET3S-5 S is designed specifically for use in emergency stop circuits, ensuring that hazardous machine functions can be stopped quickly and safely when required. It is fully compliant with EN 60947-5-1, the international standard that governs electromechanical control circuit devices. Compliance with this standard ensures the device meets stringent requirements for reliability, mechanical endurance, and safety integrity, providing peace of mind for both operators and safety managers.

One of the core strengths of the device lies in its use of AgNi (silver-nickel) contacts. This contact material offers excellent conductivity and arc resistance, ensuring consistent performance across thousands of actuations. Its durability makes it particularly well-suited for E-STOP functions, which must remain dependable even after prolonged use in demanding environments.

Another important attribute is its ability to reliably switch low currents, with a minimum contact current rating of just 1 mA. This capability allows the PIT ES SET3S-5 S to be integrated into control circuits that use low-power or sensitive electronic components without compromising reliability. This extends its usability to a wide range of machine and automation applications, where mixed load conditions are often present.

The robust design of the PIT ES SET3S-5 S ensures dependable operation even in challenging industrial environments. Whether deployed in manufacturing plants, automotive production, packaging machinery, logistics facilities, or process automation, it guarantees reliable emergency stop performance, protecting personnel and machinery alike.

In addition to its technical performance, the device is easy to install and integrate, making it a practical choice for both new systems and retrofits. Its compact build ensures minimal space requirements in control cabinets, while its durable construction supports long service life.

In summary, the Pilz PIT ES SET3S-5 S (400449) is a robust and versatile emergency stop control device designed to meet the highest standards of industrial safety. With its wide supply voltage range, durable AgNi contact design, low-current switching capability, and compliance with EN 60947-5-1, it provides a reliable foundation for protecting people and machinery across a wide spectrum of industrial applications.
