RST® MINI
RST® MINI DEVICE CONNECTOR MOLA®

The innovative, modular device connectors with spring clamp technology

FLEXIBLE AND SAFE: MOLA® DEVICE CONNECTORS 

Installations with high protective rating can be implemented with more flexibility and tailored to any application better than ever thanks to the new modular MOLA® connectors for the 
RST® MINI series.

THE ALL-ROUNDER FOR YOUR DEVICE 

These modular device connectors have been optimized especially for luminaire manufacturers. As all-rounders, however, they can also be used in engines, heaters, controllers, and similar devices. The modular RST®MINI connector makes installing a great variety of applications more flexible, quicker, and safer. 

UNBEATABLE FEATURES 

MOLA® connectors are available as 2, 3, 4, and 5-pole models. Thanks to the modular design, the internal cable harness and housing can be prefabricated separately. The spring clamp connection facilitates the connection in the luminaire housing. Plus, MOLA® is “BJB ready” – this means suitable for automatic wiring by robots. 

MOLA® helps to save valuable space. Thanks to the two connections per pole, there is no need for an internal terminal, saving space. The spring clamp connection also ensures that less space is needed during the installation than is required for a comparable installation with a screw connection.  

MOLA® is an excellent option for a solution with through-wiring. This is usually realized with a 2.5 mm² conductor cross-section – no problem with MOLA®. 

SAVES TIME 

The spring clamp connections ensure that the conductors can be plugged in very easily during luminaire installation. This saves considerable time compared to an installation involving screw connection. Time is also saved by the splitter connection per terminal point as there is no need for installation and preparation of an additional terminal and corresponding conductors.

ADVANTAGES

REPLACES AN INTERNAL TERMINAL

The internal adapter provides two connections per pole:  


Connecting channel A provides a cross section of up to 2.5 mm² and is preferably used for through-wiring.

Connecting channel B is designed for smaller cross sections and is used for the direct connection of internal devices (e.g. drivers). The labeling of the poles (dependent on the coding) is visible between the connecting channels.

Automatic wiring  

MOLA® is equipped with a push-in spring. This and the optimized lead-in chamfers allow for automatic wiring by robots, which can take place in installed condition within the device housing or separately, on a fixture for the internal adapter.   

FOR 20 MM BUSHINGS

All variants – 2, 3, 4, or 5-pole – have a diameter of 20 mm. Existing series with 20 mm bushings can be retrofitted to MOLA® quickly and integrated directly in prepared M20 bushings. This makes it easy to switch from traditional cable glands to the convenient pluggable alternative. There is the option of using a flattened top on the thread of the device connector to fix it in position.

 

MODULAR STRUCTURE

The new RST16 MOLA® device connector is completely modular, which means it consists of three separate parts. 

  • External adapter – for connecting the electrical infrastructure
  • Internal adapter with two terminals per pole – for through-wiring and for the outputs for internal wiring
  • Nut – for fastening the external adapter

 

SEPARATE PREPARATION

Thanks to the modular design, cable harness and housing can be prefabricated separately. The external adapter is connected to the housing, while the internal adapter is assembled with the internal wiring at a different place. Later, the internal adapter is simply plugged into the external adapter!

MORE SAFTY

Variants with additional contact seal (longitudinal seal) are also available as an option. They prevent the ingress of moisture into the contacts due to condensation or damaged cables.

APPLICATION BY LUMINAIRE MANUFACTURERS

MOLA® can be used for luminaires with through-wiring as well as for point source luminaires.

Through-wiring    

For applications with through-wiring, for example, the variant with 4 or 5 poles can be used. These are available as male and female models.

POINT SOURCE LUMINAIRES 

For point source luminaires, variants with 2 or 3 poles are suitable. These are available as male models.

FAQs

What is the rated current of the system?

The rated current of the RST® MOLA device connectors is 16 A.

What is the rated voltage of the system? 

The rated voltage of the system is AC 250 V / 400 V.

With what number of poles is the system available? 

2/3-pole for male models and 4/5-pole for female and male models.

What connection types are there? 

Spring force (push-in spring).

What is the size of the connector cross section? 

0.5mm² - 2.5mm² (details of the connector cross section can be found in the product assembly instructions)

What thread do the device connectors have? 

M20

What approvals are available/planned?

VDE; pending: cULus, CSA

What IP ratings are available? 

IP66 / IP68 (3m;2h) / IP69 

What is the additional “internal contact seal” for?

In practice, incorrectly executed installations, damage to the cables, or temperature differences repeatedly occur. This creates harmful moisture inside the installation. At this point, built-in barriers help to stop the water from passing on. The MOLA device connector is available with this as an option, with each single contact featuring internal sealing. In practice, this is also called “longitudinal waterproofing”.

For which applications is the system intended? 

Luminaire connection, luminaires with through-wiring, connection of electrical devices

Can I connect fine-stranded cables without ferrules? 

No. Details of the connector cross section can be found in the product assembly instructions.

Can the system be permanently operated under water?

No, temporary immersion is possible according to the specification: 3m; 2h

How are the parts packaged? 

Currently: 50 pieces. In a box. Contact carriers, incl. mounted flat seal in a bag, nuts in a separate bag, and internal adapters loose in the box.

Can I order the internal adapter separately from the external adapter? Why can’t the internal adapter be used for every coding? 

For safety reasons, a separate internal adapter for every coding is absolutely necessary (e.g. to prevent connection errors with pre-assembled internal adapter).

Why does the tool not feature the pole marking

Different codings have different pole labels – for easier handling. In addition, printing makes the pole label easier to read.

Is a reference design solution planned? Is there a “replacement fastening” for the nuts? 

No.
