Self-adhesive Spacer MM-054 by PULSAR — model MM-054, adhesive mounting spacer

Self-adhesive Spacer MM-054 by PULSAR is a pressure-sensitive adhesive mounting spacer designed to create consistent gaps, reduce direct contact between components and assist alignment during assembly or repair. The product adheres to suitable clean surfaces and functions as a simple solution for spacing, insulation separation and minor vibration damping where a stick-on spacer is required. Its compact form factor and adhesive backing enable straightforward placement without additional fasteners.

Advantages

The self-adhesive backing provides immediate adhesion to prepared surfaces, allowing rapid installation and reliable positioning. The spacer maintains a uniform gap to protect components from abrasion and short-contact, while also helping to minimize vibration transfer. Installation does not require tools or additional joining elements, and the low-profile design keeps assemblies compact. The material is chosen for stable performance in typical indoor mounting and repair environments.

Suitable for

• Creating consistent spacing between electronic components and panels
• Providing insulation separation to prevent short circuits
• Reducing contact wear and mechanical abrasion
• Minor vibration isolation in low-load assemblies
• Temporary or permanent stick-on mounting where screws are impractical

Key specifications

• Mounting type: pressure-sensitive adhesive backing for stick-on installation
• Function: spacing, insulation separation, contact protection and vibration reduction
• Form factor: low-profile spacer suitable for confined assembly spaces
• Surface compatibility: designed for clean, dry, non-porous and lightly textured surfaces
• Installation: tool-free application; peel-and-stick placement

How to use

Ensure contact surfaces are clean, dry and free of dust, grease or loose particles before application. Peel off the protective liner and press the adhesive side firmly onto the target surface, applying even pressure for a few seconds to promote adhesion. Position the spacer so that it creates the required gap or isolation between components, and allow any adhesive cure time recommended for the environment. For best results, avoid placing on surfaces outdoors or on materials that release plasticizers unless compatibility is verified.

Usage recommendations

Use the spacer on prepared, stable surfaces and avoid application on contaminated or highly flexible substrates. For electrical isolation, confirm that the material and required gap meet the specific insulation and safety standards of your application. When used for vibration damping, verify the spacer's effectiveness under the actual load and environmental conditions before critical use.
