Spotting the Difference: A Guide to WEIPU’s SF vs. SA Series Connectors
One frequently asked question by our customers revolves around choosing the right connector series for their projects – particularly when the options appear similar at first glance. WEIPU’s SF and SA series connectors share a similarity in their sleek design, often leading to inquiries about their specific differences. This article aims to clarify these subtleties, spotlighting the distinct features that set them apart despite their external similarity.
The SF series is renowned for its:
- Material: Robust brass with chrome plating for enhanced durability.
- Size Range: Available from SF6 to SF20 to accommodate various application sizes.
- Pin Options: Offers 1-15 pins to meet diverse connectivity needs.
- Power Capacity: Capable of handling up to 30A and 500V for high-power applications.
- Temperature Tolerance: Operational within a temperature range of -40°C to +85°C.
- Mating Cycles: Reliable for 500 mating cycles, ensuring a long service life.
- Certifications: Compliant with CE, RoHS, and UL (SF12 4-7 pin) standards for quality assurance.
- Protection Rating: Equipped with an IP67 rating, making it resistant to dust and temporary immersion in water.
- Coupling Mechanism: Features push-pull coupling for secure and easy connection.
SA Series: Modern and Versatile
The SA series stands out with its:
- Shell Material: Anodized aluminum for a modern, lightweight construction.
- Size Variability: Ranges from SA6 to SA28, providing options for diverse use cases.
- Extensive Pin Options: From 1-35 pins for a wide array of connection configurations.
- Current and Voltage: Suitable for up to 60A, and 500V for demanding environments.
- Temperature Capability: Also functional from -40°C to +85°C.
- Mating Cycles: Also designed for 500 uses, matching the SF series in durability.
- Color Options: Comes in standard black/silver, with additional blue, green, and red for a personalized touch.
- Certifications: Holds CE and RoHS approvals.
- Protection and Coupling: Like the SF series, the SA series is rated IP67 and employs a push-pull coupling mechanism.
Choosing Between SF and SA
Deciding between the SF and SA series involves assessing the specific needs of your project. If the charm and heft of brass appeal to you for heavy-duty applications, SF is your go-to series. However, if you’re looking for a more contemporary appearance with color customization that doesn’t compromise on strength or capability, the SA series may be more suitable.
Both series offer excellent protection against the elements with IP67 ratings and are easy to connect and disconnect with their push-pull coupling, making them versatile choices for a multitude of applications.
When choosing, consider the environment where the connectors will be used, the type of signals they’ll carry, and the aesthetic demands of the end product. Both SF and SA provide reliable and high-quality connections but cater to different stylistic and functional preferences.
