Winkhaus FM.V Wireless Window Contact Concealed EnOcean Sensor IP54 Hidden Installation

Product Overview

The Winkhaus FM.V wireless window contact is installed hidden within the rebate, between the sash and frame, and communicates the open/closed status of windows via EnOcean wireless protocol. It is used in residential and commercial smart buildings to integrate with automation systems, such as smart thermostats or security controls. Designed for PVC, wood, and aluminum windows and doors, it meets IP54 safety class requirements and operates reliably from -20°C to +60°C, ensuring suitability for varied climates.

Unlike external sensors, the FM.V's concealed installation in the rebate eliminates visual impact and tampering risks, providing unobtrusive status monitoring without altering the window aesthetics or functioning. This feature is especially valuable for B2B buyers in bulk smart home deployments or retrofits?where maintaining the original look and compatibility with a wide range of profiles is essential for project acceptance and tenant satisfaction.
