Quick Detail

Description

The 330780-91-CN 3300 XL 11 mm Proximitor Sensor is a high-performance condition monitoring component that inherits the advanced technical features of the 3300 XL 8 mm Proximitor Sensor, while optimizing for 11 mm proximity probe systems to deliver enhanced versatility in industrial applications. Designed for precise vibration, displacement, and position measurement of rotating equipment, this 330780-91-CN 3300 XL 11 mm Proximitor Sensor stands out with its compact, thin-profile design, enabling flexible mounting options that adapt to diverse industrial setups—whether in high-density DIN-rail installations for space-constrained control rooms or traditional panel mount configurations for legacy monitoring systems. This dual-mount capability eliminates installation limitations, making the 330780-91-CN 3300 XL 11 mm Proximitor Sensor a preferred choice for retrofits and new system deployments alike.​

A key highlight of the 330780-91-CN 3300 XL 11 mm Proximitor Sensor is its enhanced RFI/EMI immunity, which exceeds industry standards to ensure reliable performance in electromagnetic interference-prone environments. This robust anti-interference design allows the sensor to effortlessly meet European CE mark approvals without requiring special mounting modifications or shielding—eliminating the need for additional hardware or complex installation procedures that add cost and delay. Beyond CE compliance, the 330780-91-CN 3300 XL 11 mm Proximitor Sensor’s RFI/EMI protection effectively blocks high-frequency radio signals, power line noise, and electromagnetic emissions from nearby industrial equipment (such as variable frequency drives and motors), preventing signal distortion and ensuring the transducer system maintains accurate data output even in crowded industrial control cabinets.​

Equipped with innovative SpringLoc terminal strips, the 330780-91-CN 3300 XL 11 mm Proximitor Sensor simplifies field wiring with tool-free installation, enabling faster, more secure connections compared to traditional screw-terminal sensors. The SpringLoc design delivers robust clamping force that resists vibration-induced loosening, a critical advantage in high-turbulence environments like turbine rooms, pump stations, and compressor facilities. This user-friendly feature not only reduces installation time and labor costs but also minimizes the risk of wiring errors, ensuring consistent performance across the entire monitoring system. Compatible with 0.2 to 1.5 mm² (16 to 24 AWG) field wiring, the 330780-91-CN 3300 XL 11 mm Proximitor Sensor seamlessly integrates with existing industrial wiring infrastructures, supporting both new installations and upgrades from legacy systems.

Applications

The 330780-91-CN 3300 XL 11 mm Proximitor Sensor stands as a versatile, high-performance monitoring solution engineered to deliver precise vibration, displacement, and position data for rotating equipment across power generation, oil and gas, heavy manufacturing, aerospace, and marine industries. Its ultra-wide operating and storage temperature range of -52°C to +177°C (-62°F to +351°F) ensures unwavering performance in extreme conditions—from turbine enclosures and offshore drilling platforms to cold outdoor substations and high-humidity marine environments. Complemented by a compact 12cm×8cm×4cm footprint, 0.35kg lightweight design, and DIN rail mounting option, the sensor seamlessly integrates into high-density control cabinets and confined equipment spaces, while its 0 mm minimum unthreaded length enhances installation flexibility. With a standard 5.0-meter (16.4-foot) cable length (and optional 9.0-meter system length) and compatibility with 0.2 to 1.5 mm² (16 to 24 AWG) field wiring, it supports long-distance connections without compromising signal integrity, thanks to its 50 Ω output resistance and low 69.9 pF/m (21.3 pF/ft) capacitance that minimize attenuation and electromagnetic interference. Backed by multiple agency approvals, it meets strict industry safety standards for hazardous and critical applications, while its -17.5 Vdc to -26 Vdc power requirement and supply sensitivity of less than 2 mV/V ensure stable data output amid voltage fluctuations. Whether monitoring turbine shafts in power plants, compressor rotors in refineries, gearboxes in manufacturing facilities, or ship propulsion systems, this sensor provides reliable, high-fidelity data to drive predictive maintenance strategies, reduce unplanned downtime, and safeguard operational efficiency across diverse industrial landscapes.

Specifications

Competitive Advantage

1. Unmatched Durability in Ultra-Extreme Operating Environments

Boasting an ultra-wide operating and storage temperature range of -52°C to +177°C, the sensor delivers consistent performance in extreme environments—from freezing outdoor power substations and high-heat turbine enclosures to humid marine engine rooms and corrosive oil refinery settings. This temperature tolerance far exceeds that of standard industrial proximitor sensors, eliminating the need for additional thermal protection and ensuring long-term reliability in mission-critical applications.

2. Space-Efficient Design Enabling Versatile Installation Flexibility

With a compact footprint of 12cm×8cm×4cm and a lightweight 0.35kg build, the sensor fits seamlessly into high-density control cabinets and confined equipment spaces. Its DIN rail mounting option simplifies integration into standard industrial control systems, while the 0 mm minimum unthreaded length and 150 mm overall case length optimize installation for both retrofits and new system deployments. The dual length options (5.0 meters standard, 9.0 meters system length) cater to both short-distance and long-distance wiring needs, eliminating the hassle of cable splicing and reducing installation time.

3. Superior Signal Integrity for Precise, Stable Data Transmission

Equipped with 50 Ω output resistance and a low typical capacitance of 69.9 pF/m, the sensor minimizes signal attenuation and electromagnetic interference (EMI) during data transmission, ensuring high-fidelity vibration and displacement measurements for rotating equipment. Its supply sensitivity of less than 2 mV output voltage change per volt input voltage change guarantees stable data output even amid grid voltage fluctuations, a critical advantage in industrial environments with unstable power supplies. Compatibility with 0.2 to 1.5 mm² (16 to 24 AWG) field wiring further enables seamless integration with existing industrial infrastructure.
