Quick Detail

Description

The 84661-90 Sensor Proximity Probe Cable stands as a high-reliability signal transmission solution engineered specifically for proximity probe systems, designed to bridge the gap between industrial sensors and monitoring devices across critical sectors. As an integral component of condition monitoring setups, the 84661-90 Sensor Proximity Probe Cable delivers uncompromised signal integrity, durability, and compatibility—key attributes for supporting accurate vibration, displacement, and position measurements in harsh industrial environments. Whether deployed in power plants, oil refineries, manufacturing facilities, or heavy machinery operations, this cable is built to withstand extreme conditions while ensuring consistent data transmission that forms the backbone of predictive maintenance strategies.

At the core of the 84661-90 Sensor Proximity Probe Cable’s performance is its precision-engineered construction, optimized for minimal signal attenuation and electromagnetic interference (EMI) resistance. The cable features a high-quality coaxial design with low capacitance and impedance matching, ensuring that the weak electrical signals from proximity probes are transmitted without distortion over extended distances. Its robust insulation material—selected for thermal stability and chemical resistance—protects internal conductors from moisture, oils, corrosive gases, and mechanical abrasion, extending service life even in environments with temperature fluctuations, high humidity, or exposure to industrial chemicals. Additionally, the 84661-90 Sensor Proximity Probe Cable incorporates a durable outer jacket that enhances mechanical strength, preventing damage from routing through tight spaces, equipment vibration, or accidental impact during installation and operation.

Applications

1. Power Generation: Core Rotating Equipment Monitoring​

Ideal for thermal/hydropower facilities, this cable connects probes to monitors for steam turbines, generators, and feedwater pumps. Its -40°C to +85°C temperature range withstands extreme weather and machine room fluctuations, while the 3.0-meter length suits short-distance wiring for small-to-medium power units. At 2.3x2.2x69cm and 0.14kg, it routes flexibly in dense setups. 55 pF/m low capacitance and 50 Ω output resistance ensure impedance matching, minimizing signal loss for accurate rotor vibration and shaft displacement data (1.5mm linear range).​

2. General Manufacturing & Automation: Production Line Component Surveillance​

Widely used in auto lines, machine tools, and assembly systems, it links proximity probes to PLCs/data loggers for motor, conveyor, and robotic arm monitoring. The 3-meter length fits workshop wiring needs, with compatibility for 0.2–1.5 mm² (16–24 AWG) field wiring enabling seamless integration. Compact (0mm unthreaded length, 40mm case) and lightweight, it installs easily in tight spaces. /V supply sensitivity and low capacitance resist voltage fluctuations and EMI, ensuring precise transmission of positioning and speed data for automated closed-loop control.​

3. Heavy & Construction Machinery: On-Site Working Condition Monitoring​

Certified for safe use in excavators, cranes, and road rollers, this cable adapts to outdoor construction’s extreme temperatures. The 3-meter length connects on-equipment sensors to on-board monitors, with a wear-resistant outer layer resisting dust, collisions, and abrasion. 50 Ω output resistance and low capacitance deliver accurate vibration and hydraulic component data, letting operators track equipment status in real time. Lightweight (0.14kg) and flexible, it avoids interfering with machinery movement while simplifying installation and maintenance.​

4. Chemical & Light Industry: Process Equipment Status Tracking​

Suitable for chemical reactors, papermaking, and textile machinery, it connects probes to control center systems for agitator and drive roller monitoring. Stable electrical performance (50 Ω, 55 pF/m) resists EMI and humidity, ensuring undistorted signals. The 3-meter length fits workshop layouts, and multi-certifications meet chemical industry safety standards. Compact dimensions (2.3x2.2x69cm) facilitate routing in dense areas, with a lightweight design reducing modification and maintenance efforts for continuous production support.

Specifications

Competitive Advantage

1. High-Fidelity Signal Transmission with Stable Electrical Performance​

Boasting 55 pF/m low capacitance and 50 Ω output resistance, the cable ensures precise impedance matching with proximity probes and monitors, minimizing signal attenuation over its 3.0-meter length. With supply sensitivity /V, it resists voltage fluctuations and EMI, delivering accurate data for 1.5mm linear range measurements—critical for reliable condition monitoring.​

2. Compact & Lightweight Design for Flexible Installation​

At 2.3x2.2x69cm and 0.14kg, paired with 0mm unthreaded length and 40mm case length, the cable fits seamlessly into tight spaces and dense equipment layouts. Its 3.0-meter (9.8-foot) length suits short-to-medium distance wiring, while compatibility with 0.2–1.5 mm² (16–24 AWG) field wiring enables hassle-free integration with existing systems, reducing installation time and labor costs.​

3. Broad Temperature Tolerance for Versatile Environments​

Operating from -40°C to +85°C (-40°F to +185°F), the cable adapts to extreme weather, machine room fluctuations, and outdoor construction sites. This wide range eliminates the need for application-specific variants, simplifying inventory management and ensuring consistent performance across diverse industrial scenarios.
