GAURANG 157mm Din Rail Enclosure
Features include a low-height enclosure designed for compact instruments and an innovative clip design that changes its position in the base plate to facilitate wall or rail mounting. Suitable for popular embedded boards like Raspberry Pi, Arduino, BeagleBone, and ODROID. This model is best for compact control panels where space efficiency is critical and wiring needs are evolving.
Best for: Small home automation or industrial projects that require side access for terminations and easy mounting. Why selected: The 157mm form factor balances board space with enclosure protection, while the mounting clip versatility helps adapt to different installation constraints.
Caution: Ensure clearance for terminal wiring on both sides if using dense cabling. Check rail compatibility with your DIN rail type before installation.
GAURANG 70mm Din Rail Enclosure (Complete Closed)
This model provides a complete closed solution with a low-height footprint, designed for compact instruments. The enclosure supports wall/rail mounting via base-plate adjustments, making it suitable for embedded boards like Raspberry Pi and Arduino. It’s a solid choice when you need a simple, protected housing with minimal external access.
Best for: Small control panels requiring robust protection and minimal footprint. Why selected: The closed design offers straightforward protection for sensitive electronics while maintaining DIN-rail compatibility.
Caution: Internal space is limited; verify component dimensions to avoid crowding and overheating in dense layouts.
GAURANG 70mm Din Rail Enclosure (Both Side Terminals)
Designed with dual-side terminal access, this enclosure enhances wiring flexibility while keeping a compact 70mm body. It remains compatible with Raspberry Pi, Arduino, BeagleBone, and ODROID boards, and its clip-based mounting in the base plate allows easy positioning for rail or wall mounting. This is a good middle-ground choice when you need more wiring access without expanding the enclosure size.
Best for: Projects requiring easier terminal access without sacrificing a compact DIN-rail footprint. Why selected: Dual-side terminals simplify complex wiring schemes in small enclosures.
Caution: The tighter internal space may limit larger connectors; plan wire routing accordingly.
GAURANG 105mm Din Rail Enclosure (Both Side Terminals)
This 105mm enclosure offers more internal space while maintaining a din rail form factor. It supports popular embedded boards and provides dual-side terminals to accommodate more wiring configurations. It’s a better option when your project requires additional components or longer terminal rows without increasing the enclosure footprint excessively.
Best for: Projects needing extra space for boards and connections while staying DIN-rail friendly. Why selected: The larger interior makes it easier to fit multiple modules or larger terminal blocks.
Caution: Larger size increases the distance to the rail; ensure mounting rails and enclosure depth align with panel requirements.
GAURANG 35mm Din Rail Enclosure (Both Side Terminals)
This ultra-compact enclosure fits slim DIN-rail systems where space is extremely limited. The 35mm size still offers dual-side terminals for flexible wiring. It is well-suited for microcontroller projects and small sensor arrays that require a discreet, mountable housing.
Best for: Tiny control boxes and space-constrained installations. Why selected: It provides essential protection with the most compact footprint among the GAURANG range.
Caution: Limited space means careful planning of component layout and cable routing is essential to avoid crowding.
Buying Guide
What to consider when choosing a din rail enclosure
- Size vs. required space: Match the enclosure dimensions to your board and component footprint. Larger enclosures provide more wiring room, but increase mounting depth.
- Terminal access: Single-side or dual-side terminals affect how you route wires. Dual-side access improves wiring flexibility in tight layouts.
- Mounting versatility: Look for base-plate clips or adjustable mounting features for rail or wall mounting.
- Protection rating: For indoor/outdoor use, consider IP ratings and environmental protection suitable for your installation.
- Board compatibility: Ensure it can accommodate Raspberry Pi, Arduino, BeagleBone, or ODROID-sized boards with enough clearance for connectors.
- Material and durability: ABS enclosures provide good protection and light weight; assess heat dissipation needs for your components.
- Wiring ease: Consider internal layout and terminal block spacing to prevent short circuits and simplify maintenance.
How to compare options quickly
- Best for compact spaces: 35mm and 70mm enclosures with minimal depth.
- Best for wiring flexibility: Dual-side terminal models.
- Best for more components: 105mm and 157mm enclosures with extra internal space.
Installation tips
- Plan cable routes before mounting; mark terminal entry points to minimize cross-wiring.
- Ensure the enclosure cover fits securely to prevent dust ingress and water exposure if used outdoors.
- When using wall mounting, verify clearance for any external connectors and cooling paths.
FAQ
- What is a DIN rail enclosure best for? It protects electronics while allowing reliable rail mounting in control panels and automation setups.
- Can these enclosures fit Raspberry Pi and Arduino boards? Yes, several GAURANG models are designed for popular embedded boards with appropriate mounting options.
- Are dual-side terminals better than single-side? They offer more wiring flexibility, especially in tight layouts, but may require more space inside.
- What about weatherproof use? Check IP rating and material; most indoor enclosures don’t provide full outdoor protection unless specified.
- How do I choose the right size? Consider both the board footprint and connector spacing; leave extra room for future expansion and cable management.
- Is installation difficult? Most enclosures use clip-based mounts and standard terminal blocks; follow manufacturer dimensions and mounting instructions for best results.
