The housing developed for programmable logic controllers is a practical and efficient solution for those seeking to integrate automated control in various applications.

Designed to facilitate the implementation of electronic projects, it is compatible with 25mm DIN rails, allowing easy installation in electrical panels and industrial environments. In addition, the design includes a 16x2 LCD display and four control buttons, providing an intuitive interface for monitoring and adjustments.

With 24V power outputs and connection for up to four relays, this housing offers versatility and practicality for the development of automatic controllers, allowing users to access and customize the design according to their needs, with the option of 3D printing.

By purchasing this housing, developers gain a robust and adaptable structure, ideal for creating reliable and professional automation systems.

Below we will present the complete project documentation.

Project Objective

The objective of this project is to develop a modular and functional housing for programmable logic controllers (PLCs), aimed at facilitating the assembly and integration of automation systems. The enclosure was designed to accommodate essential components, such as a 16x2 LCD display, four control buttons, 24V power outputs and connections for up to four relays, in addition to being compatible with 25mm DIN rails.

With a focus on accessibility and practicality, the project aims to offer a solution that allows easy customization and 3D printing, meeting the needs of electronic project developers in different applications.

Materials Used

To develop this electronic enclosure you must use the following materials:

SLA 3D Printing - Body Electronic Enclosure

SLA 3D Printing - Cover Electronic Enclosure

04 x Screws 2 mm

Technical Specifications

The dimensions of the electronic enclosure are shown below.

Below we will present the structure of the internal housing and its dimensions. The structure was developed to allow the developer to install some electronic boards, such as: control circuit, button board and relays to activate loads. To help you develop your circuit board from this electronic enclosure, we provide a model with the interna dimensions for you to consider during the development process of your PCB.

From the dimensions above we can develop the structure of the electronic board and determine the best position for each electronic component.

In addition to the cover and base, we have connectors for 35 mm DIN rail. This allows for more flexibility in the installation of the electronic housing.

To fix the connector to the DIN rail, we use 4 screws to fix it to the base of the controller. In the attachments of this article you can find the step file with each 3D part.

Screws

These DIN rail connectors have 2 holes for fixing to the base structure of the housing using screws. Below we present the screws for fixing to the electronic enclosure structure.

All electronics enclosure dimensions are shown below. You can access them to determine the enclosure dimensions for your project.

Below we will present the assembly structure of the electronic enclosure with the screws and the insertion nut.

Assembly Process

The assembly process is very simple and is represented by the structure below. The electronic housing does not require screws to fix the base and the lid, as it uses a press fit system, which ensures a simple fit and opening.

The electronic housing presented can be used in a variety of applications. Its assembly process is very simple and you can use PCBWay's manufacturing services right now to manufacture it with quality 3D printing and industrial finish.

Do you want parts with a finish similar to thermoplastic injection? Print with PCBWay at a low price, with a variety of materials and quality.

The project was tested on the bench and showed excellent results after 3D print process with FDM 3D Printer.
