What Should You Check Before Choosing A Junction Box Manufacturer?

Enclosure Cover

Junction Box

The enclosure cover can be set to transparent so clearly monitor the status of the equipment inside. In thermoplastic enclosures, the whole cover is either grey or transparent. Grey covers are available both in ABS and polycarbonate. Transparent covers are available only in polycarbonate. VSM Plast terminal enclosures are also made of die-castaluminium. Modular enclosures come with a hinged window available either in smoke-grey or transparent.


Enclosure walls

Junction Box

The material thickness of our thermoplastic enclosures is greater than that of similar products in the market. This helps in the machining of threads. In addition, the usage of e.g. push buttons on the cover is safer since the material is more rigid. The bases of polycarbonate enclosures with knockouts have been manufactured using high-grade polycarbonate in order to add rigidity to the enclosure walls and to make it easier to knock out the cable entries. We have a modular tooling structure, enabling cost-efficient mould modifications. This is especially efficient when making customer-specific holes and cut-outs in a large series of enclosures.


Gasket

Junction Box

We use injected, jointless PUR (polyurethane) gaskets in our thermoplastic and aluminium enclosures to ensure a high protection class. The standard gasket material of our aluminium and polyester enclosures is silicon.


The gasket that we use has the following temperature operating variations:

  • Polyurethane: -40-+80°C

  • Neoprene: -40-+100°C

  • Silicone: -50-+150°C

Mounting Plates

Junction Box

Our mounting plates are made of Bakelite material as standard. The material thickness of the plates varies between 1.5 - 3.0 mm, depending on the size of the plate. On customer request, mounting plates can be available materials such as stainless steel or non-conductive material. We customise mounting plates according to the customer's configurations, e.g. with threaded holes and cut-outs. Mounting plates are included as standard in our VSM Plast E and EO wall cabinets made of aluminium.


Hinges

Junction Box

Our range of standard VSM Plast enclosures includes hinged wall cabinets in thermoplastic and aluminium. The position of the hinges can easily be changed from one side to the other in the case of VSM Plast Enclosures, even as the final operation at the installation site. All our enclosures can be hinged on request. Hinges can be found among our accessories. Our offering also includes hingedcover screws available for VSM Plast enclosures and the VSM Plast panel building system.


Locking and Sealing

Junction Box

All our enclosures can be locked or sealed if necessary. The VSM Plast E and EO wall cabinets made of aluminium contain locks as standard. Our range of accessories includes different lock options. VSM Plast thermoplastic wall cabinets can be locked with a padlock, without any other accessories. The covers and the cover screws of VSM Plast S, C, O, W thermoplastic enclosures are equipped with sealing holes, through which the enclosures can easily be sealed.


Enclosure Cover Screws

Junction Box

Thermoplastic enclosures have several cover screws options. These can be seen among our list of accessories. The enclosures are equipped with slotted/cross head screws as standard. VSM Plast enclosures come with metallic cover screws. Hinged cover screws are available for the VSM Plast O and C thermoplastic enclosures and VSM Plast P-panel building system. Thanks to these innovative screws, the cover can easily be opened, even if it is in the middle of a panel, and the cover screw.
