As a result this enclosure is ideal for applications requiring environmental exposure such as sensors. This enclosure is light grey in colour, measures 60 x 60 x 20mm, and is ideal for mounting printed circuit boards. Slots on the base allow for easy wall-mounting and a knockout on the base can be removed with a screwdriver and used for wire entry. Made from ABS plastic, it has a satin texture finish and snap-fit assembly which can be reopened repeatedly as needed. PCB standoffs are moulded into the interior and it is designed to meet IP30. The manufacturer's part number is 1551V3GY.

This Hammond 1551V3GY miniature plastic enclosure is designed for hobbyists and professionals needing to protect electronic components in environmentally exposed applications, such as sensors. Its key benefit is providing robust protection while allowing necessary air and moisture exchange. A potential caveat is its IP30 rating, which offers basic protection against solid objects but minimal protection against liquids. This enclosure features a vented design, snap-fit assembly for repeated access, molded PCB standoffs, and a removable knockout for wire entry.

FAQs
What does IP30 mean?
IP30 is an Ingress Protection rating. '3' signifies protection against solid objects greater than 2.5mm (like tools or fingers). '0' signifies no specific protection against water.
Can I drill additional holes in the enclosure?
Yes, ABS plastic can be drilled, but do so carefully to avoid cracking the enclosure. Be mindful of the placement of internal components and PCB standoffs. Drilling will also compromise the IP rating.
How many PCBs can this enclosure hold?
This enclosure is designed to hold one standard-sized small PCB, utilizing the internal standoffs for mounting.
Is the enclosure suitable for outdoor use?
Due to its IP30 rating, it is not recommended for outdoor use where it would be exposed to rain, dust, or high humidity without additional protective measures.
What are the internal dimensions?
While specific internal dimensions are not provided, the external dimensions are 60 x 60 x 20mm. Account for the molded standoffs and wall thickness when planning internal component placement.
Can the snap-fit lid be permanently secured?
The snap-fit design is intended for repeated opening. For permanent security, you would need to explore adhesive or mechanical fastening methods not included with the enclosure.
Troubleshooting
Enclosure lid does not snap shut securely.
Ensure no wires or components are obstructing the lid's closure. Check for any debris within the snap-fit grooves and ensure the internal PCB is seated correctly.
Wire entry knockout is difficult to remove.
Apply firm, steady pressure with a screwdriver. Ensure you are using the correct screwdriver for the size of the knockout and avoid excessive force that could damage the enclosure.
Internal components are overheating.
Verify that the vents are not blocked. For applications generating significant heat, consider if this enclosure's ventilation is sufficient or if a different enclosure type is needed.
Enclosure feels flimsy.
ABS plastic offers moderate durability. Ensure the enclosure is properly snapped shut. For applications requiring higher impact resistance, consider enclosures made from different materials.

Setup, Compatibility & Care
Setup:
Prepare for Wire Entry: If wire entry is needed, use a screwdriver to carefully remove the pre-marked knockout on the base of the enclosure.
Mount PCB: Place your printed circuit board inside, aligning it with the molded standoffs for secure positioning.
Close Enclosure: Align the lid with the base and press gently until the snap-fit connectors engage.
Mount Enclosure: Use the slots on the base to mount the enclosure to a flat surface if required.
Compatibility:
Designed to house small printed circuit boards (PCBs).
Suitable for components requiring ambient air exposure.
The IP30 rating means it is protected against solid objects larger than 1mm but offers no protection against water.
Care:
Clean the exterior with a slightly damp cloth. Avoid abrasive cleaners or solvents.
Ensure the vents are clear of dust and debris for proper airflow.
If repeatedly opening and closing, check the integrity of the snap-fit mechanism.
