Mechanical protection with optimal air permeability

The plastic guard grilles are inserted directly into the foot holes of the LM shrouds and offer reliable protection against mechanical damage. Available in two variants for different hole patterns.

Technical Highlights:

• Material: PA6/PA66, black, UL94-V-0 flame retardant
• Tool-free plug-in assembly into shroud feet
• Type 01: Minimal outer dimensions, Type 02: Hole pattern cover
• Compatible: LM-25 to LM-119 series

EMI shielding with up to 50% improvement in EMI tightness

High-precision stainless steel grilles for electromagnetic compatibility and touch protection. Measurable damping improvement across the entire frequency range with maximum airflow.

Three hole variants available:

• RE: Round perforation offset (75% free cross-section)
• SE: Hexagonal perforation offset (85% free cross-section)
• SH: Hexagonal perforation for SLM shrouds (85% free cross-section)

Material: Stainless steel V2A, 0.2mm material thickness
Compatible: LM-25 to LM-119 as well as SLM series

Contamination protection with unrestricted function

PVC-free plastic mesh prevents the ingress of insects and contaminants. Ideal for outdoor applications and critical environments.

Versions:

• SF: For LM shrouds with plug-in feet
• SN: For SLM shrouds with plug-in nipples

Material: Plastic mesh anthracite, 0.2mm, REACH/RoHS compliant
Mounting: Tool-free with shrouds or screws
