FAQ:

Is the WT29 series suitable for outdoor use?

Yes. The wide temperature range (-40°C~+85°C) and V-0 flame resistance make it suitable for outdoor scenarios such as security cameras and outdoor lighting.

Is the WP20 series suitable for the high-vibration working condition of load-bearing machines?

Yes. The WP20 series with zinc alloy shell is specially adapted to high-vibration scenarios. The bayonet coupling mechanism can ensure firm locking without loosening under high-load vibration, and the high-strength zinc alloy shell can resist the impact of vibration, ensuring the stable operation of the load-bearing machine control system.

What is the significance of the 2000V AC test voltage (1min)?

The 2000V AC test voltage (1min) is an important indicator to verify the insulation performance of the connector. It means that the connector can withstand the test of 2000V AC voltage for 1 minute without breakdown or leakage. This indicator ensures that the connector can operate safely and reliably in high-voltage scenarios, avoiding electrical safety hazards caused by poor insulation.

Can the RJ45 Series be used in outdoor rainy environments for a long time?

Yes. The RJ45 Series has an IP67 protection rating, which can prevent the intrusion of dust and water (immersion in water at a depth of 1 meter for 30 minutes). It can be used in outdoor rainy environments for a long time, but it should be ensured that the bayonet is fully locked during installation to maintain the waterproof performance.

What is the advantage of the M23X Series' ultra-high insulation resistance (>10¹³mΩ)?

The ultra-high insulation resistance can effectively isolate electrical signals between different circuits, avoid mutual interference, and ensure the accuracy of signal transmission in precision control scenarios. At the same time, it can greatly reduce the risk of electrical leakage and short circuit, improving the safety of equipment operation and protecting the personal safety of operators.
