📘 Product Introduction
The 3500/40M 125680‑01 is a 4-channel Proximitor® Monitor designed for high-precision measurement of shaft vibration, position, and phase. It works seamlessly with proximity sensors to convert raw signals into actionable condition data, allowing for real-time diagnostics and machinery protection.
Each channel pair can be configured for different monitoring tasks such as radial vibration, axial thrust, differential expansion, or eccentricity—making the module incredibly versatile and reliable.
It is compact, rack-mounted (occupying one full-height slot), and integrates easily into 3500 Series systems, making it an essential part of modern industrial condition monitoring architectures.
