Coaxial connectors facilitate the connection between two pieces of equipment such as between cables, RF antennas, satellite dishes, and electronic components. MRF1.6/5.6-LPJ-179U is one of such coaxial connectors. This article will provide a brief description on the application field and working principle of this connector.

MRF1.6/5.6-LPJ-179U is a low-frequency search and rescue (LF-SAR) connector and belongs to the family of field-replaceable Type N-SAR connectors. This connector has an IP67 rating for water ingress protection, making it suitable for harsh environmental conditions and hence, it is used in applications such as marine, aerospace, oil and gas, and mining. The connector mates with an LPJ-127U jack and provides IP67 sealed mating between devices.

The body of the connector consists of a two-piece aluminun housing. The pin is constructed with an O-ring collar that serves to seal the pin when it is inserted into a female jack. The pin is also made of stainless steel and has a gold-plated contact.

The working principle of MRF1.6/5.6-LPJ-179U is based on maintaining a continuous electrical connection with minimal noise and attenuation. When the contact is mated, the pin is inserted into the jack and an internal pin spring mechanism provides an electrical path while maintaining the necessary pressure required to ensure the contact remains reliable over time and despite environmental conditions.

When the connector is mated, the electrical contact is formed between the internal pin spring mechanism and the gold-plated contact. The contact is then secured in place with an internal retention sleeve. This ensures the contact is kept in place, reducing the risk of contact segmentation or damage which can lead to electrical signal deterioration, noise or attenuation.

The built-in low-pass filter of the MRF1.6/5.6-LPJ-179U connector works to limit high frequency energy, reduce noise, and improve RF performance. The internal pin spring also provides additional shielding to minimize any unwanted energy.

In conclusion, MRF1.6/5.6-LPJ-179U is a low frequency search and rescue connector used in applications such as marine, aerospace, oil and gas, and mining. Its working principle is based on maintaining a continuous electrical connection with minimal noise and attenuation. The IP67 rating ensures water ingress protection. The internal pin spring provides additional shielding to minimize unwanted energy. This makes it a suitable choice for harsh environmental conditions.
