Product Q&A

Q:What is the difference between rhombus panel mount and round panel mount?

The rhombus flange has two or four mounting holes at the corners, providing stronger anti-rotation and vibration resistance compared to round flanges. It prevents the connector from spinning after installation, making it ideal for equipment that experiences frequent vibration or torque.

Q:What is the waterproof rating of this SP21 connector?

The SP21 connector is rated IP68, which means it can withstand continuous immersion in water up to 1.5 meters depth for 30 minutes. It is suitable for outdoor equipment, marine applications, and wet environments.

Q:How many wiring methods are there?

There are two types, one is screw locking and the other is welded.

Q:What pin configurations (number of pins) are available?

The SP21 series is available in 2, 3, 4, 5, 6, 7, 8, 9, 10,12,16,20,24 and 26 pins. Common options are 2-12pin.

Q:What is the panel cutout hole size required for mounting?

The standard panel cutout diameter are 11mm, 13mm, 17mm, 21mm, 29mm, can provide a detailed dimension drawing upon request.
