A hardwired sensor that detects impact or vibration and includes an integrated reed switch. Ideal for protecting windows, glass panels, and entry points by combining shock detection and contact monitoring.
🔑 Key Features
Dual sensing: vibration (mass inertial) sensor plus built‑in reed contact
Gold‑plated, self‑cleaning contacts for corrosion resistance
Configurable as non‑latching (momentary) or latching operation
Dual LED indicators for power and alarm status
Durable metal casing to reduce magnetic interference
Can be mounted vertically or horizontally
đź› Technical Specifications
Model: WSD02 (often as WSD02A in product lines)
Sensing Type: Mass inertial vibration + reed switch
Contact Output: Normally Closed (N/C) dry contact
Mounting Orientation: Horizontal or vertical
Power Supply: Typical low voltage (e.g. 9–16 V DC)
Housing: Metal shell for shielding and longevity
Indicators: Dual LEDs (one for power, one for alarm)
Mode Selection: Non‑latching or latching setting
Compatibility: Designed for integration into wired alarm systems
Environment: Indoor applications, close to glass or entry zones
🎯 Best Used For
Glass break / window protection: Senses impact plus contact change
Doors & fragile panels: Adds vibration sensing to standard contact monitoring
High-security zones: Combines two detection methods into one device
Versatile installations: Works in different orientations without performance loss
Hybrid detection systems: Useful where both shock and contact signals are needed
