Product Specifications

Technical details and manufacturing context for Tamper-Detection Mesh

Definition
A tamper-detection mesh is a security component used in secure enclosures, such as security key storage systems, to detect physical tampering attempts. It consists of a conductive network or sensor grid that covers vulnerable surfaces. When integrated into a secure enclosure, the mesh continuously monitors for physical breaches, cuts, or unauthorized access attempts. Any such event triggers immediate alerts or security protocols, protecting sensitive cryptographic keys and data. The mesh is available in various configurations, with detection areas ranging from 100 to 10,000 cm², mesh pitch from 0.5 to 5.0 mm, and conductor width from 0.1 to 0.5 mm. Resistance per square ranges from 0.5 to 10 Ω/sq, and the break resistance threshold is set between 100 and 1000 kΩ to distinguish tampering from normal variations. Operating temperature ranges from -40 to 85 °C, storage temperature from -40 to 125 °C, and relative humidity from 5% to 95% RH (non-condensing). Ingress protection is rated IP54 to IP67, depending on encapsulation. Substrate materials include PET and PI, conductor materials include Cu and Ag, and adhesive types include acrylic and silicone. Peel strength ranges from 5 to 15 N/cm, and weight per area from 50 to 200 g/m². The mesh is made from materials such as conductive polymer composite, copper alloy wire mesh, or flexible printed circuit material. It is important to verify model-specific values and standards with the legal manufacturer or supplier, as the listed ranges are reference values for directory purposes.
Working Principle
The mesh operates as a continuous electrical circuit or sensor network. Any physical breach, cut, or deformation of the mesh changes its electrical properties, such as resistance, capacitance, or continuity. Monitoring circuitry detects these changes and triggers security responses, such as erasing cryptographic keys, sounding alarms, or logging intrusion events. The break resistance threshold is set to distinguish tampering from normal variations, ensuring reliable detection.

Risk, maintenance & compliance

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Mesh fatigue fracture
Cause: Cyclic stress from thermal expansion/contraction or vibration exceeding material endurance limit, often due to improper tensioning or support spacing.
Corrosion-induced weakening
Cause: Galvanic corrosion at dissimilar metal contact points or environmental chemical attack, accelerated by moisture ingress or incompatible material selection.
Maintenance Indicators
  • Visible sagging, kinks, or localized deformation in mesh pattern indicating loss of tension or structural compromise
  • Audible rattling or high-frequency vibration noises during normal operation signaling loose connections or broken strands
Engineering Tips
  • Implement regular tension verification using calibrated tension gauges during thermal cycles to maintain optimal 85-90% of yield strength preload
  • Apply corrosion-inhibiting dielectric coatings at connection points and ensure cathodic protection where applicable, especially in humid/chemical environments
