6-Port Unmanaged Industrial Switch | 4-RJ45 Ethernet Ports, 2-SFP Fiber Ports

Rugged 6-Port Gigabit Industrial Ethernet Switch

The SF70660 is designed for industrial Ethernet networks that require reliable connectivity between copper Ethernet devices and fiber optic network segments.

With four Gigabit RJ-45 ports and two 1000Mbps SFP slots, the switch provides a practical combination of copper and fiber interfaces for blended network environments.

Its unmanaged architecture allows compatible Ethernet devices to be connected without requiring complex network configuration, while the industrial hardware provides protection against the environmental and electrical conditions commonly encountered in field installations.

Gigabit Copper and Fiber Connectivity

The SF70660 includes four 10/100/1000Mbps copper Ethernet ports and two 1000Mbps SFP fiber slots.

The copper ports support:

• 10Mbps Ethernet
• 100Mbps Fast Ethernet
• 1000Mbps Gigabit Ethernet
• Auto-negotiation
• Auto-MDI/MDI-X
• Full-duplex flow control
• Half-duplex back-pressure flow control

The two SFP slots provide flexibility for selecting compatible Gigabit fiber transceivers based on the fiber type and required transmission distance.

Flexible SFP Fiber Options

The SF70660 accepts compatible 1000Mbps SFP modules, allowing the fiber interface to be configured for different network distances and fiber types.

VERSITRON's available Gigabit SFP options include:

• Multimode fiber up to 220 meters
• Multimode fiber up to 550 meters
• Multimode fiber up to 2 km
• Single-mode fiber up to 10 km
• Single-mode fiber up to 20 km
• Single-mode fiber up to 40 km
• Single-mode fiber up to 70 km
• Single-mode fiber up to 100 km
• Single-fiber bidirectional options up to 80 km

The available SFP modules use LC connectors. CWDM and DWDM modules are also available.

The appropriate SFP module should be selected according to the network's fiber type, transmission distance, wavelength, and connector requirements.

12Gbps Switching Capacity

The SF70660 provides 12Gbps switching capacity with a non-blocking store-and-forward switching architecture. The switch supports a 4K MAC address table and maximum frame sizes up to 9.6K bytes.

This architecture allows the switch to efficiently forward Ethernet traffic between its copper and fiber interfaces without requiring network management configuration.

Unmanaged Plug-and-Play Operation

The SF70660 is designed as an unmanaged industrial Ethernet switch, making it appropriate for installations where straightforward Ethernet connectivity is preferred over configurable Layer 2 management.

The switch automatically handles compatible Ethernet connections through auto-negotiation and auto-MDI/MDI-X functionality.

This makes the SF70660 a practical choice for extending existing Ethernet networks into industrial or remote environments without adding configuration requirements at the switch.

Redundant DC Power

The SF70660 supports dual 9–52VDC power inputs, providing a redundant power architecture for installations where continued network operation is important.

The switch has a specified power consumption of approximately 7W, helping keep the power requirements low in industrial installations.

4KV Ethernet Surge Protection

The SF70660 incorporates 4KV Ethernet surge protection as part of its industrial protection features. The product family is also designed with industrial-rated emission and immunity performance.

These features help make the SF70660 suitable for Ethernet installations where connected equipment may be exposed to electrical disturbances.

IP44 Industrial Metal Enclosure

The SF70660 is housed in an IP44 metal enclosure designed for industrial applications. The housing is corrosion resistant and supports DIN-rail mounting.

The compact industrial enclosure makes the switch suitable for equipment cabinets, control panels, machinery, transportation systems, and other installations where ruggedized network equipment is required.

Extended Temperature Operation

The SF70660 is designed to operate across an extended temperature range of -40°C to +80°C. The same range is specified for storage. Relative humidity is rated at 0% to 95%, non-condensing.

This wide operating range allows the switch to be deployed in industrial environments where standard commercial Ethernet switches may not be appropriate.

DIN-Rail Installation

The SF70660 supports DIN-rail mounting, allowing it to be installed directly inside industrial control cabinets and equipment enclosures.

The switch measures approximately 4.49 × 3.70 × 1.42 inches and is designed for space-conscious industrial installations.

High Reliability for Industrial Networks

The SF70660 has an MTBF greater than 100,000 hours, providing a long-life hardware platform for continuous industrial Ethernet operation.

The combination of redundant DC power, surge protection, rugged metal construction, extended temperature operation, and DIN-rail installation makes the SF70660 well suited to industrial network environments where reliability is important.
