Inventarna številka:61F-LS-CP11-NRA
Package size: 15X15X12CMProduct Overview
The Omron 61F-LS-CP11-NRA industrial limit switch is a premium-grade electromechanical device engineered for precision position sensing and reliable operation in demanding automation environments. As part of Omron's globally trusted 61F series, this SPDT (Single Pole Double Throw) limit switch combines rugged construction with advanced contact technology to deliver consistent performance in applications ranging from heavy machinery to precision assembly systems. Featuring an IP67-rated sealed housing, it excels in environments exposed to dust, moisture, and temperature fluctuations from -25°C to +85°C (-13°F to 185°F). With a 10-million-cycle mechanical lifespan and 500,000 electrical operations at rated load, this switch is backed by Omron's 1-year limited manufacturer warranty for guaranteed quality assurance.
Key Features & Engineering Advantages
