Why Choose the Pizzato FD521-T6 Position Switch?

The Pizzato FD521-T6 is a heavy-duty industrial position switch from the FD series, designed for reliable mechanical detection in extreme automation environments. This variant includes an extended wide temperature range (T6), making it ideal for applications exposed to very low ambient conditions.

It features a coil spring actuator with cat’s whisker tip, allowing flexible and responsive actuation where alignment tolerance and sensitive detection are required. The rugged metal housing provides excellent resistance to vibration, dust and harsh industrial conditions, ensuring long-term reliability.

With a 1 normally open + 1 normally closed (1 NO + 1 NC) snap-action contact configuration, PG13.5 conduit entry and IP67 protection rating, the FD521-T6 is engineered for demanding environments requiring dependable switching and extended temperature performance down to -40 °C.

Key Advantages

  • Heavy-duty position switch for industrial automation.
  • T6 extended temperature range down to approximately -40 °C.
  • Flexible coil spring actuator with cat’s whisker for precise detection.
  • 1 NO + 1 NC snap-action contacts for versatile control circuits.
  • Durable metal housing for harsh environments.
  • IP67 protection rating ensures resistance to dust and water.

Key Features

  • Pizzato FD series position switch.
  • Spring rod actuator with wire tip (cat’s whisker).
  • 1 NO + 1 NC snap-action contact block.
  • T6 version for low-temperature operation.
  • Robust metal enclosure.
  • PG13.5 threaded conduit entry.
  • External gasket sealing for enhanced ingress protection.

Reliable Position Detection in Extreme Environments

Position switches such as the Pizzato FD521-T6 are essential in industrial automation systems for detecting movement, position and end-of-travel conditions. They provide accurate feedback to control systems, ensuring safe and efficient machine operation.

The T6 variant extends the usability of the FD series into cold environments such as outdoor machinery, refrigeration systems and low-temperature industrial processes, while maintaining the same robust mechanical performance.
