Proximity sensors

Overview

The Bently Nevada 330780-90-00 is a high-performance 3300 XL 11 mm Proximitor Sensor designed to deliver precise vibration and displacement monitoring in demanding industrial applications. Featuring a slim design, it is ideal for both high-density DIN-rail and traditional panel mount installations. The sensor offers excellent RFI/EMI immunity, ensuring compliance with European CE mark standards. It also comes with advanced features, including secure field wiring connections with SpringLoc terminal strips, reliable ClickLoc connectors, and a robust CableLoc design for reliable cable attachment.

This system supports various probe configurations, including armored and unarmored designs. Additionally, FluidLoc® cables prevent oil leakage, and connector protectors increase durability in humid environments.

Key Features

• Enhanced RFI/EMI Immunity
  The sensor minimizes interference from high-frequency signals, ensuring stable operation even in electrically noisy environments.
• SpringLoc Terminal Strips
  These terminal strips simplify field wiring, allowing for quick and secure connections without the need for special tools.
• Gold-Plated ClickLoc Connectors
  The connectors prevent loosening and ensure high reliability. CableLoc provides a 330 N (75 lb) pull strength for secure cable attachment.
• FluidLoc Cable Option
  This option prevents oil or liquid leakage, enhancing safety and operational reliability in hazardous environments.
• Environmental Durability
  The sensor features a locknut with predrilled safety wire holes and silicone tape for additional protection in harsh conditions.
