Stewart Connectors Get Protective Coating
Connectors with protective coating.
Glen Rock, PA — Stewart Connector, a division of Bel Fuse Inc. has released RJ11 and RJ45 connectors using EPP-918A (Environmentally Protective Product). This proprietary protective compound was developed to provide both pore blocking and lubricating properties to extend the life of voice and data connections, providing superior moisture, humidity, dirt, chemical, and corrosion resistance.
The protective product also shields against wear resulting from repetitive mating/un-mating forces. The compound, which is applied to the gold-plated contacts during manufacturing, contains Ultraviolet (UV) tracer dye to enable visual inspection. EPP-918A is available on any of the company's parts in addition to RJ45 or RJ11 jacks which are offered shielded/unshielded, with 1 to 12 ports, in vertical and right angle configurations, and with/without LEDs. Jacks have added green benefits because their increased usable life reduces the waste associated with discarded electronic components.
These newly available connectors are well suited for virtually any commercial, consumer, and industrial application where environmental protection and/or multiple mating cycles are required. Included among their most common usages are in FTTH (Fiber to the Home), industrial Ethernet, and outdoor network and communications equipment. They are equally appropriate in military field equipment, field test equipment, EMT communications devices, fire and law enforcement equipment, marine environments, and in mining, oil, and manufacturing applications.
The connectors have an operating temperature range of -40 to +85°C, and withstand high temperature soldering in excess of 260°C for 10 seconds. The RoHS-compliant jacks' LLCR (Low Level Contact Resistance) reliability tests indicate no significant changes to gold-plated contacts to 2500 cycles. EPP-918A adheres to contacts instantly upon application and remains intact to preclude the need for additional tape, mechanical barriers, or cure time often associated with competitive products.
