The Pilz PSEN HS1.2P (570271) is a dependable safety switch with guard locking, designed to secure access points on machinery and equipment in compliance with stringent international safety standards. By combining durable contact performance with flexible operating conditions, it ensures that operators are protected while enabling smooth and efficient machine operation.

This switch is engineered for use in safety-critical applications where guard doors, flaps, or covers must remain locked until hazardous movements have come to a complete stop. It is tested and certified to EN 60947-5-1, confirming compliance with utilisation categories AC15 and DC13, making it suitable for switching both AC and DC safety circuits.

On the AC side, the PSEN HS1.2P supports a 230 V AC safety contact voltage with a maximum current capacity of 3 A (AC15), allowing it to reliably switch contactors, relays, and other actuators in safety circuits. On the DC side, it is rated for 24 V (DC13) safety contacts, ensuring compatibility with modern low-voltage control systems. This dual capability enhances its versatility, allowing it to be deployed across a wide range of industrial applications without additional adaptation.

Built to withstand demanding environments, the PSEN HS1.2P operates in ambient temperatures from -25 °C to +70 °C. This broad operating range makes it suitable for installations in both chilled storage facilities and high-temperature industrial production areas. Its rugged design ensures reliable long-term performance, even under mechanical stress, frequent operation, or fluctuating environmental conditions.

As part of the Pilz PSEN family of safety switches, the HS1.2P integrates seamlessly into complete safety systems when used alongside PNOZ safety relays, PSS control systems, or Pilz modular I/O modules. This compatibility supports the development of scalable and standards-compliant safety architectures, reducing engineering effort and ensuring consistent system behaviour.

The switch is ideally suited for industries such as automotive, packaging, robotics, material handling, and process automation, where ensuring operator protection and preventing accidental machine access are vital. By reliably monitoring guard positions and controlling access, the PSEN HS1.2P helps operators work safely while also supporting high levels of machine uptime.

In summary, the Pilz PSEN HS1.2P (570271) is a rugged and versatile safety switch with guard locking. With its AC/DC compatibility, strong contact ratings, wide operating temperature range, and compliance with EN 60947-5-1, it offers an effective solution for safeguarding personnel and equipment in modern industrial automation systems.
