The Pilz PIT ES3S-C (part no. 400143) is a robust and versatile control and signal device engineered to support emergency stop (E-STOP) and machine control functions in demanding industrial environments. Built as part of the Pilz PITcontrol series, this unit combines high durability with compliance to international standards, making it a reliable choice for safeguarding both personnel and machinery.

A key feature of the PIT ES3S-C is its broad supply voltage compatibility, supporting operation on 12–30 V AC/DC. This flexibility allows it to be integrated into a wide range of machine and control system configurations without the need for multiple device variants. Whether connected to traditional AC-based systems or modern DC-based architectures, it delivers consistent performance, simplifying design and inventory management for system integrators.

The device’s IP65-rated housing makes it highly resilient to dust and resistant to low-pressure water jets, ensuring reliable operation even in harsh industrial environments. This level of protection allows the PIT ES3S-C to be installed in exposed areas where it may be subjected to cleaning processes, airborne particles, or moisture, making it particularly suitable for industries such as food processing, packaging, and material handling.

Another strength of the unit is its wide ambient temperature range of -25 °C to +55 °C. This ensures dependable operation in both chilled environments and warmer production facilities, providing flexibility across diverse application scenarios. Coupled with its pollution degree 3 clearance and creepage classification, the device maintains safe insulation and reliable operation even in atmospheres where dust, dirt, or industrial residues may be present.

Designed with usability and safety in mind, the PIT ES3S-C offers fast and reliable activation in emergency conditions. As part of the emergency stop function chain, it provides operators with a direct means of halting hazardous machine operations immediately, preventing accidents and reducing the risk of costly damage. Its clear actuation and ergonomic design ensure it can be quickly and confidently triggered, even under stressful conditions.

When integrated with Pilz safety relays or programmable safety systems, the PIT ES3S-C becomes part of a comprehensive machine safety solution that complies with standards such as ISO 13849 and IEC 62061. This integration ensures full compliance while enabling efficient machine design and streamlined commissioning.

In summary, the Pilz PIT ES3S-C is a durable, flexible, and standards-compliant control and signal device designed to provide reliable E-STOP functionality in industrial automation. With its 12–30 V AC/DC supply compatibility, IP65 housing, wide operating temperature range, and robust safety design, it is ideally suited for safeguarding machinery in demanding environments while ensuring operator protection and system reliability.
