The Pilz PIT ES SET6U-5 CR (part no. 400451) is a high-quality emergency stop (E-STOP) device belonging to Pilz’s trusted PITcontrol series. Engineered to meet the stringent requirements of international safety standards, this device is designed to provide fast and reliable emergency shutdown of machinery, helping to protect personnel and equipment in critical industrial environments.

At the heart of the PIT ES SET6U-5 CR is its compliance with EN 60947-5-1, the international standard governing emergency stop switches. This certification guarantees that the device meets all electrical and mechanical safety requirements, ensuring reliable operation in the event of an emergency. When triggered, the switch immediately disconnects hazardous machine movements, minimising the risk of injury and preventing costly equipment damage.

The switch features AgNi (silver-nickel) contacts, known for their excellent electrical conductivity and resistance to wear. These contacts deliver consistent performance over long service lives, even under frequent actuation. Their robustness also reduces the risk of contact welding, a key factor in maintaining system reliability in safety-critical applications.

With a minimum contact current rating of 1 mA, the PIT ES SET6U-5 CR is capable of handling low-power control signals reliably, making it suitable for sensitive circuits as well as standard safety wiring. This flexibility broadens its application range, ensuring dependable performance across a variety of industrial machines and control architectures.

The device is designed to withstand demanding environmental conditions, with an operating temperature range of -25 °C to +55 °C. This wide range ensures reliable functionality in diverse industrial environments, from refrigerated facilities to warm production plants. In addition, its IP65-rated housing offers strong protection against dust ingress and low-pressure water jets, allowing the device to be installed in areas exposed to dirt, humidity, or cleaning processes. This makes it particularly useful in industries such as food and beverage, packaging, and material handling.

Practicality is another strength of the PIT ES SET6U-5 CR. Its compact yet durable design supports easy installation into control panels, operator consoles, or machine housings. The switch’s ergonomic layout ensures that operators can quickly and confidently engage the emergency stop function when required, supporting both safety and usability.

As part of the Pilz PITcontrol range, the PIT ES SET6U-5 CR integrates seamlessly into comprehensive safety architectures. When paired with Pilz safety relays or controllers, it contributes to fully standards-compliant machine safeguarding systems that enhance both safety and operational efficiency.

In summary, the Pilz PIT ES SET6U-5 CR emergency stop device combines robust construction, standards compliance, and reliable performance to deliver a trusted solution for industrial safety. With its silver-nickel contacts, IP65 protection, wide operating temperature range, and EN 60947-5-1 certification, it ensures dependable emergency stop functionality across a wide range of demanding applications.
