Active VR Speed Sensors - EMI Susceptibility Hardened

DME Series

Motion Sensors DME series of active variable reluctance (VR) speed sensors are similar to our standard DM series amplified sensors. The DME series offers EMI (Electromagnetic Interference) susceptibility hardening and improved performance in environments with greater external electrical noise and disruptions. The DME series is equivalent to the Honeywell 584xx series while also offering CE compliance and additional pulse output offerings.
