Xelivor
Engineered for high mechanical life, compliant with standard telecommunications and electronics enclosures in San José & Alajuela zones.
Costa Rica has transformed into a high-technology industrial hub in Central America, driven by the expansion of its Free Zones (Zonas Francas) in regions like Coyol, Alajuela, and Cartago. With global electronics manufacturing services (EMS) and medical device OEMs establishing large-scale facilities here, the demand for high-integrity interconnection hardware—ranging from standard RJ11 modular jacks for sensor control loops to optical transceivers for regional data centers—has escalated.
As Costa Rica’s telecom giant ICE (Instituto Costarricense de Electricidad) and private operators deploy advanced fiber networks, legacy sub-systems and industrial environments continue to rely heavily on RJ11/RJ12 infrastructure. This creates a hybrid ecosystem where reliability at the physical layer determines the performance of localized control devices, building automations, and telecommunication hardware.
By providing direct support to the Costa Rican manufacturing sector, Xelivor ensures supply chain flexibility, customization on gold-plating thickness, and strict RoHS/REACH compliance necessary for medical and industrial applications.
We combine optical transceiver manufacturing with robust copper interconnect solutions to support hybrid telecom systems.
We support customization levels from gold flash up to 50u" gold plating to prevent contact oxidation under tropical high-humidity conditions common in Costa Rica.
Designed for automated reflow and wave soldering processes with high-temperature LCP/Nylon housings (UL94V-0), preventing board warping and solder defects.
Every modular jack is tested for mechanical insertion fatigue, contact resistance, and dielectric breakdown to match international standards (UL 1863, FCC Part 68).
Complementary fiber optic network solutions for enterprise datacenters and high-speed switches in Costa Rica.
Critical engineering insights for selecting modular connectors in humid tropical environments.
Connectors operating in Costa Rica, specifically near industrial areas of Cartago or agricultural automation systems in Limón, face environmental factors such as high relative humidity, thermal cycling, and potential exposure to chemical agents in agri-tech. Standard unshielded connectors can experience galvanic corrosion at the contact points over time. Xelivor addresses this by utilizing high-performance copper alloy contacts with nickel under-plating and varying gold plating options. For outdoor telecom boxes, smart meters, and grid controllers, we advise using at least 30u" to 50u" gold plating to ensure the electrical path remains hermetic and oxide-free.
Globally, standard analog connections (RJ11 and RJ12) are transitioning to RJ45 Ethernet and Fiber Optic interfaces (such as LC/SC and high-speed SFP/QSFP structures). However, legacy RJ11 connectors (6P2C, 6P4C, or 6P6C configurations) remain highly prevalent in security systems, building management systems (BMS), elevator communication, DSL lines in remote Costa Rican locations, and power monitoring hardware. A typical setup utilizes an RJ11 port for low-speed serial diagnostic communication (RS-232 / RS-485), leaving high-speed channels to optical and Ethernet cables. Standardizing on high-quality modular jacks that can handle minor electrical surges and constant mechanical cycles is vital to minimizing network maintenance costs.
Modern production facilities must comply with strict international regulatory systems. All RJ11 and SFP cage components manufactured by Xelivor comply with RoHS 2.0 (Restriction of Hazardous Substances) and REACH regulations, critical for OEMs exporting their finished products from Costa Rica’s Free Zones to the European Union and North America. Mechanical tolerances are strictly designed according to FCC Part 68 subpart F rules to ensure universal mating compatibility with all standard RJ11 plugs.

Answering key queries on modular jack selection, shipping, and technical compatibility for the Costa Rican market.
RJ11 and RJ12 share the same physical size (6-position shell), but RJ11 typically features 4 contacts (6P4C) used for voice and basic analog systems, while RJ12 uses all 6 contacts (6P6C) and is common in system phones and proprietary key systems. RJ45 is physically larger (8-position shell, 8P8C) and is the standard interface for Ethernet cabling (Cat5e, Cat6, Cat6A).
Yes, we ship directly to major free zones in Costa Rica (Coyol Free Zone, Metro Free Zone, etc.) via air freight and ocean freight. We handle all international supply chain documentation to ensure smooth customs clearance in San José (SJO Airport) or Puerto Limón.
Gold is highly resistant to oxidation and corrosion. In high-humidity tropical areas like Costa Rica, standard unshielded modular jacks with low gold plating (gold flash) can experience corrosion, leading to packet loss or intermittent connections. We recommend 30u" or 50u" gold-plated contacts for demanding industrial automation and telecom hardware.
Yes, our engineering team provides complete customization including plastic housing materials (LCP, Nylon, ABS with UL94V-0 ratings), tab direction (Tab Up/Tab Down), shielding configurations (with/without EMI metal tabs), and customized pinouts for specialized control boards.
