Product Overview
The model of MMCX female cable crimp connector is MMCX-C-K1.37.MMCX series are 50 ohms micro-miniature connectors, smaller than MCX.With characteristics of smaller size, less weight, and easy installation, they are used in large mount to connect RF cable transmitting signals in applications where size and weight are critical,particularly in modular products for GSM/GPRS/3G and in other networks. They are packaged in tray or reel, which is efficient to SMT inlarge quantity.Due to its unique design, the MMCX interface usually has clear positive and negative polarity requirements when connected to ensure the stability and reliability of signal transmission.
Identifying MMCX Connector Polarity
The polarity of an MMCX connector primarily refers to the electrical polarity of the center pin inside the connector and the outer shield. In practical applications, correctly identifying the polarity of an MMCX connector is crucial, especially for signal transmission and device stability. The following describes how to identify the polarity of an MMCX connector:
1. Positive (Center Pin):
In MMCX connectors, the center pin is generally considered the positive terminal. This center pin is the key component for signal transmission and connects to the positive signal terminal of the source or destination device. Typically, the positive terminal is connected to the inner conductor of a circuit board or cable.
2. Negative (Casing/Shield):
The negative terminal is typically the outer casing of the connector, which serves as the ground and shield. During connection, the negative terminal should be connected to the device's ground or external grounding system to prevent signal interference and noise.
