Product Update: G41, G47 and G81 Relay Options for High-Voltage RFQs

Sorint is highlighting G41, G47 and G81 high-voltage relay options for buyers who need compact relay references in high-voltage control panels, test equipment, DC power systems and service spare programs. These product families give procurement teams a practical starting point when an RFQ calls for a power relay supplier that can review exact model numbers, contact arrangement, voltage class and mounting details before quotation.

This update focuses on verified catalog data already available in Sorint product records. Buyers should still confirm final suitability against their own engineering requirements, drawings and approvals, especially when a relay is being considered as a replacement for an existing part.

G41 relays for 5kV control requirements

The G41 group includes models such as G41A232, G41B232 and G41C232. The available records show 5kV relay options with SPST-NO, SPST-NC and SPDT contact arrangements. The listed G41A232 and G41B232 references use tungsten contact material, 30A current rating, 3-hole flange mounting, solder pot high-voltage connection and a 12 Vdc non-latching coil with bus wire termination.

For buyers comparing compact high-voltage relay references, those details are useful because the RFQ can quickly separate contact form, coil voltage, mounting and termination questions. The G41 records also show a -55 to +125 C operating temperature range, 10 ms operate and release times, 10G vibration, 50G shock and Reach and RoHS compliant status. Sorint can use that information as a first review point while the buyer confirms project-level requirements.

G47 and G81 options for higher voltage classes

For RFQs that move beyond the 5kV class, G47 and G81 references may be relevant to the initial sourcing review. The G47A232 record lists an 8kV SPST-NO relay with 12A current rating, 3-hole flange mounting, solder pot high-voltage connection, 12 Vdc non-latching coil and bus wire coil termination. Its product data shows vacuum dielectric, 2 million mechanical cycles, -55 to +125 C operating temperature, 10 ms operate and release times, 10G vibration and 30G shock.

The G81A2A5 record is a 10kV SPST-NO relay reference with 10A current rating. Its record lists PC board mounting, PCB pin high-voltage connection, 12 Vdc non-latching coil, PC pin coil termination, 2 million mechanical cycles and a -55 to +85 C operating temperature range. That makes the G81 family especially important to identify accurately in an RFQ because the mounting and termination details are different from flange-mounted, solder-pot relay references.

How buyers can make relay RFQs easier to quote

A high-voltage relay RFQ is easier to review when the request includes the full model number, contact arrangement, voltage class, current expectation, coil voltage, mounting style, termination requirement and target quantity. If the inquiry supports maintenance or a replacement review, buyers should provide the original reference, the desired candidate reference and any drawing or approval requirement that controls the purchasing decision.

Sorint can help procurement teams organize those details before quotation, but relay selection remains project-specific. A 5kV SPDT relay, an 8kV SPST-NO relay and a 10kV PC-board relay should not be treated as interchangeable simply because they sit in the same broad product category. Package, terminals, coil option, contact form, temperature range and approval requirements all need buyer-side confirmation.

Where this update fits in sourcing plans

The G41, G47 and G81 relay references are useful for buyers building a shortlist for high-voltage control circuits, industrial test fixtures, DC power control panels and service replacement programs. They can also help purchasing teams identify when a quote request needs a compact SPST or SPDT relay rather than a higher-current DC contactor or a fuse protection product.

When sending a relay RFQ to Sorint, buyers can include the complete model list, quantities, expected delivery window and application background. That gives our team enough context to review availability, confirm next questions and respond with a clearer sourcing path.

FAQ for G41, G47 and G81 relay inquiries

Can Sorint review G41, G47 and G81 relay requests together?

Yes. Buyers can send grouped relay RFQs when the request includes complete model numbers, quantities and application background. Sorint can then review the list and confirm the next quotation questions.

Are G41, G47 and G81 relays interchangeable?

No automatic interchangeability should be assumed. The records show different voltage classes, contact arrangements, mounting styles and termination details, so the buyer's engineering team must confirm suitability before purchase.

What details should be included in a high-voltage relay RFQ?

Include the exact part number, contact form, voltage and current requirements, coil voltage, mounting style, termination style, target quantity, delivery window and any approval or drawing constraints that affect sourcing.
