Question 1

How does this magnetic latching relay differ from a standard relay?

Accepted Answer

It changes state through a control pulse and retains the last contact position after coil power is removed. The exact set/reset logic depends on the selected model.

Question 2

What load information should I provide before selecting the current rating?

Accepted Answer

Please provide the AC or DC voltage, continuous current, load type, inrush current, switching frequency, and expected operating environment. The final rating is subject to confirmation.

Question 3

What coil voltages are available for this relay?

Accepted Answer

Common options may include 5VDC, 6VDC, 9VDC, 12VDC, 24VDC, or 48VDC, depending on the model. Please confirm the control voltage before ordering.

Question 4

What pulse width and polarity are required for set and reset?

Accepted Answer

The required pulse width and polarity vary by model and coil configuration. Please follow the confirmed wiring diagram and electrical specification.

Question 5

Do you offer both single-coil and dual-coil latching relays?

Accepted Answer

Both configurations may be available depending on the model. Please confirm whether your controller uses polarity reversal or separate set/reset outputs.

Question 6

Which contact form and pole configuration should I choose?

Accepted Answer

Please confirm whether the circuit requires normally open or normally closed contacts and whether it is single-phase, two-pole, or three-phase. A wiring diagram is recommended before ordering.

Question 7

Can the terminal shape and mounting dimensions be customized?

Accepted Answer

Customization can be evaluated upon request. Please provide a drawing, sample, PCB layout, or required terminal dimensions for engineering confirmation.

Question 8

What materials are used for the contacts and terminals?

Accepted Answer

Material selection depends on the model and electrical rating. Copper terminals and silver-alloy contact systems are common, but exact grades and surface treatments should be confirmed before ordering.

Question 9

Does the relay remain completely cool after the control pulse?

Accepted Answer

Pulse operation reduces coil heating, but contact temperature rise still depends on load current, contact resistance, terminal design, connection quality, and ambient conditions.

Question 10

Is this relay suitable for smart meters, EV chargers, or energy storage equipment?

Accepted Answer

It may be suitable for these applications, but the load profile, switching voltage, standards, terminal layout, and control logic must be confirmed for each project.

Question 11

What contact state should I expect when the relay is first installed?

Accepted Answer

The initial state may be affected by model design, handling, or transport. Apply the specified initialization or reset procedure before normal operation.

Question 12

What quality checks should be confirmed for bulk orders?

Accepted Answer

Recommended items include coil resistance, set/reset operation, contact resistance, dimensions, terminal condition, temperature rise, dielectric performance, and application-specific load tests. Acceptance limits are subject to confirmation.

Question 13

What information is required for an OEM magnetic latching relay project?

Accepted Answer

Please provide drawings or samples, electrical ratings, coil voltage, set/reset logic, terminal dimensions, installation space, target standards, and expected order quantity.

Question 14

How are the relays protected during transportation?

Accepted Answer

Packaging methods depend on terminal structure and order quantity. Trays, partitions, protective covers, or other solutions may be evaluated to protect terminals and separate models.

Question 15

Can I order samples or combine different models in one order?

Accepted Answer

Sample and mixed-model options depend on the selected models, customization level, and order quantity. MOQ and lead time are subject to confirmation.
