Intelligent, configurable systems that integrate with your industrial and regulated installations.
MAJ Solutions designs, develops and integrates automation and electronic solutions tailored to your technical and operational constraints. From our Interlock solution for airlock management to energy metering systems and bespoke electronic developments, we provide scalable solutions, customised to the requirements of each project.
Our Interlock solution
Intelligent, configurable airlock management
An access management solution designed to control door opening sequences in controlled environments.
Developed by MAJ Solutions, our Interlock solution manages and secures airlock operation through configurable interlocking logic, adapted to the constraints of each installation.

Key features
- Intelligent access managementDoor openings coordinated according to authorisations, airlock states and the defined operating conditions.
- Configurable opening conditionsManagement of time delays, differential pressure thresholds and opening sequences according to the requirements of the installation.
- Simplified configuration and visualisationA web interface to configure the system and view door states and available measurements in real time.
- Integration and scalabilityCan be integrated with BMS/EMS supervision systems, access control devices and installations with several doors or airlocks.
Discover our Interlock solution
- selection of active doors, from two upwards, and door-to-door logic chains
- release by time delay or by differential pressure control, with configurable pressure thresholds and opening and closing delays
- interfacing with access badge systems and fire alarm panels, management of door state sensors
- red and green illuminated button, dedicated manual override button, global emergency release of all access points, explicit status indication for each monitored door
- configuration entirely through a web interface secured by login and password, on a protected URL, with no additional software
- real-time view of door and sensor states, locally as well as remotely
- state histories that can be used for qualification activities
- direct connection to BMS or EMS systems over Modbus TCP or Profinet
These functions are described in the product sheet. It is the configuration of a given project that is decided case by case.
Solutions & developments
Solutions adapted to your industrial applications
Beyond our Interlock solution, MAJ Solutions designs and develops bespoke technical systems to meet specific needs in automation, energy management and industrial electronics.
Smart energy metering
Measure, centralise and make use of your energy consumption.
We develop metering solutions adapted to your installations, to collect measurement data, break down consumption by equipment or by use, and make it easier to integrate into your supervision systems.
Bespoke automation modules
Automate specific functions and upgrade your existing installations.
We design automation modules adapted to your processes: sequence management, equipment control, interlocks and interfaces with existing systems.
Bespoke electronic development
Create the electronic interfaces and functions your needs call for.
We develop specific electronic boards, modules and interfaces for signal acquisition, equipment control or functions that standard solutions do not cover.
Configuration & integration
Solutions designed to integrate with your installations
Every installation has its own equipment, constraints and operating requirements. We adapt our solutions to your technical environment, whether that means configuring an existing system or developing specific functions.
Customisable operation
Sequences, time delays, measurement thresholds, authorisation conditions and operating parameters are defined according to the needs of your application and the configuration options of the solution.
Integration with your existing equipment
Our solutions can be designed to communicate with your sensors, PLCs, access control systems or supervision tools (BMS, EMS), depending on the interfaces and protocols available.
Scalable solutions
When standard settings are not enough, we can adapt or develop specific functions to meet new needs or support the evolution of your installations.
Our support
From design to commissioning
MAJ Solutions supports you at every stage of developing and integrating your solution, with an approach adapted to the technical and operational constraints of your project.
1. Analysis & design
We define the functional requirements, the technical constraints and the architecture of the solution, taking existing equipment and systems into account.
2. Development & configuration
We develop or configure the necessary automation, interfaces and electronic components, then prepare their integration.
3. Integration & testing
We carry out the assembly, wiring and integration of the various components. Functional tests, FAT and SAT can be performed according to project requirements.
4. Commissioning & support
We handle commissioning, final checks and the handover of technical documents. Where needed, we can also support qualification (IQ/OQ/PQ), user training and technical support.
Our work can cover all of these steps or focus on a specific phase of your project.
Applications & environments
Solutions adapted to your industrial applications
Our solutions meet concrete needs, from access management in controlled environments to the automation of specific functions.
Airlocks & controlled environments
Management of opening sequences and access authorisations in pharmaceutical airlocks, laboratories and cleanrooms. Operating conditions can include door states, time delays and differential pressure measurements.
Energy monitoring & metering
Metering solutions to track consumption by equipment, area or use, centralise measurement data and make it easier to use.
Modernisation & industrial automation
Adding or adapting automation functions on existing installations: sequence management, interlocks, equipment control and communication with the systems in place.
Instrumentation & bespoke electronics
Development of interfaces, boards and electronic modules for specific signal acquisition, control or equipment-to-equipment communication needs.
Frequently asked questions
Your questions about our configurable solutions
Answers to the key questions on configuring, integrating and implementing our solutions.
Can the Interlock solution be adapted to different airlock configurations?
Yes. Our Interlock solution lets you adapt opening sequences, time delays and authorisation conditions to the constraints of the installation. Configurations with several doors or several airlocks can also be considered, with an architecture defined according to the needs of the project.
Can your solutions communicate with our existing equipment and supervision systems?
Yes. Depending on the characteristics of the installation, our solutions can be integrated with existing PLCs, sensors, access control devices and supervision systems (BMS, EMS). Communication interfaces and protocols are defined according to the equipment and the requirements of the project.
Can your solutions be integrated in a pharmaceutical environment subject to GMP requirements?
Yes. Our solutions can be designed and integrated taking into account the specific constraints of pharmaceutical and regulated environments. We can also support FAT/SAT testing, technical documentation and IQ/OQ/PQ qualification activities, according to the applicable requirements and the project scope.
