Product overview and where it fits
The SimtoLink EMC shielded conductive-gasket enclosure puts conductive gaskets and partitioned bays at the cover and the seams. That cuts enclosure leakage and port coupling for sensitive analog acquisition, precision-instrument front ends, and communications equipment, including sites next to variable-frequency drives and welding shops.
Shielding tracks aperture area, waveguide vents, and the I/O filters you choose. On the order, name the connector types and the cable count so the gasket cross-section and fastening torque can be locked into the hardware specification.
Choosing the gasket and the structure
Typical gaskets are conductive silicone strip, finger stock, and beryllium-copper springs. Match them to flange stiffness, compression, and the environment (salt spray, solvents). An observation window should use a metal-mesh interlayer or coated glass, bonded continuously to the frame. Ordinary tempered glass does not shield; use it only where the leakage limit is loose, or where a separate shielded bay is already in place.
Aluminum-alloy variants can bond to the gasket through conductive anodizing or a local plating. Put the bond resistance and the maintenance requirement in the contract. Shielding attenuation in dB changes with frequency and with the sample structure. Use the third-party or SimtoLink test report shipped with the unit.
Reliability on site
A conductive gasket takes a permanent set under long compression. On the maintenance cycle, check contact resistance and look for damaged gasket faces.
After the cover is opened, tighten the screws in stages along the diagonals so one section of the gasket is not crushed. SimtoLink recommends logging each EMC spot check and each structural change.
Key hardware parameters
The ratings below are the typical build of this enclosure, written so a specifier can cite them in a bid clause. For a wider range, redundant power, or an intrinsically safe variant, ask SimtoLink for the hardware specification and the installation and commissioning guide. Order codes in the same family can differ slightly; the nameplate and the documents in the box govern.
| Parameter | Specification | Notes |
|---|---|---|
| Material | Galvanized sheet metal + conductive paint | Forms a continuous bond loop with the conductive gasket |
| Ingress protection | IP54 | Indoor duty; outdoor use needs a seal and coating review |
| Dimensions | Wall mount 300×250 mm (depth per order) | Cutouts and silkscreen can be customized |
| Door | Metal door / shielded-mesh observation window (optional) | High-shielding builds should avoid an all-glass window |
| Cooling | Fan module | Waveguide vent optional; temperature rise ΔT depends on the build |
| EMC | Partitioned bays + continuous conductive-gasket bonding | Typical emissions Class A, per the measured report |
| Load | Static load 30 kg | Seismic resistance |
| Certification | RoHS | Other marks follow the project and the order code |
| Color | RAL7035 and others (powder coat) | Bare metal or a special color on request |
| Grounding | M6 copper busbar | Equipotential bonding |
Typical applications
Four field patterns for this enclosure, useful when you are laying out a cabinet and checking payback:
Acquisition station beside a drive
Limits conducted and radiated disturbance on analog signals and communication ports.
Laboratory instrument front end
Low-level signal conditioning and A/D front-end gain share one shielded enclosure.
Wireless coexistence cabinet
Cellular and Wi-Fi modules sit in a separate bay from sensitive controllers, which cuts intermodulation.
Rail transit low-voltage systems
A reinforced structure when the EMC limits are tighter.
Installation, grounding, and maintenance
- Run incoming and outgoing lines in shielded cable with filtered connectors, and ground the armor as shown on the drawing.
- Bond the enclosure to the cabinet busbar at low impedance. Do not paint over conductive contact faces.
- Prefer honeycomb waveguide or cutoff waveguide plates for vents, and avoid large open apertures.
- After maintenance, recheck the door gap and screw torque, and sample surface transfer impedance when needed.
- Do not drill the enclosure on site. That breaks the shield. New connectors go through a change order.
Ordering, documents, and support
SimtoLink supplies the hardware specification, dimension drawings, a wiring table, and sample projects for this enclosure. Volume orders can include a sample review and in-plant inspection. Warranty and calibration follow the contract and the documents shipped with the unit.
