The Pilz PSEN SL-1.0P 2.1/PSEN SL-1.0FM 1 UNIT (570661) is a versatile safety switch with guard locking, designed to safeguard personnel and machinery by combining access control and safety monitoring in one robust device. As part of the PSEN SL family, it provides a dependable solution for applications where machine access must be securely controlled and hazardous operations reliably interrupted.

Operating on a 24 V DC supply, the PSEN SL-1.0P integrates seamlessly into industrial control systems, ensuring compatibility with standardised safety architectures. Its 7.2 W power consumption reflects an optimised design that delivers robust performance without unnecessary energy demand, making it suitable for continuous use in demanding environments.

The device features three inputs, each accepting 24 V DC signals, providing engineers with flexible connectivity options for integrating safety functions such as emergency stops, enabling switches, or additional interlocks. This flexibility allows the switch to be tailored to a wide range of machine configurations and operational requirements.

One of the standout characteristics of the PSEN SL-1.0P 2.1 is its integrated guard locking mechanism. This function ensures that access to hazardous machine areas is only possible when it is safe to enter—such as after a machine has come to a complete stop. By combining safety switch monitoring and guard locking in one unit, it simplifies installation, reduces wiring complexity, and enhances overall system reliability.

The device is engineered to comply with strict international safety standards, supporting applications that require conformity with EN ISO 13849-1 and IEC 62061. When paired with Pilz safety relays or controllers, it contributes to achieving higher safety categories and performance levels, ensuring that operators and machinery are fully protected.

Compact and durable in design, the PSEN SL-1.0P withstands the environmental stresses of industrial use, including vibration, temperature fluctuations, and frequent operation cycles. This resilience ensures a long service life and reduced maintenance requirements, making it a cost-effective investment for machine builders and operators.

Typical applications include monitoring and controlling safety gates, protective covers, and access doors in industries such as packaging, automotive, robotics, and process automation. In these scenarios, the switch provides reliable locking to prevent premature access while ensuring machines are safely powered down before entry is allowed.

In summary, the Pilz PSEN SL-1.0P 2.1/PSEN SL-1.0FM 1 UNIT (570661) is a robust, flexible, and standards-compliant safety switch with guard locking. With its 24 V DC operation, integrated locking, multiple input channels, and durable design, it offers a complete solution for ensuring safety and productivity in modern industrial environments.
