Hirschmann 942132009 SPIDER-SL-20-04T1S content_copy

The Hirschmann SSL20-4TX/1FX-SM (SPIDER-SL) is an industrial, non-manageable Ethernet switch designed for mounting on a DIN rail. The device features four RJ45 network ports and one single-mode fiber optic port with SC interface, making it suitable for connecting Ethernet devices in industrial environments, especially where a combination of copper and fiber optic cables is required. The non-manageable architecture means that no configuration via network protocols such as SNMP or web interface is possible; instead, the switch operates in plug-and-play mode with automatic detection of connections.

Applications
This switch is intended for use in industrial applications, such as manufacturing automation, power supply, or process control. DIN rail mounting allows for compact installation in enclosures. The IP30 protection rating safeguards the device against solid foreign objects with a diameter of at least 2.5 mm, but does not protect against water or dust. Therefore, the device is suitable for indoor use, but not for outdoor or humid environments.

Features and Specifications in Detail
The device provides four RJ45 ports for connecting Ethernet devices such as PCs, sensors, or controllers. Data transmission occurs at Fast Ethernet speed, i.e., 100 Mbit/s. The integrated single-mode fiber optic port with SC connector enables connections over longer distances, typically up to several kilometers, depending on the network setup. The fiber optic interface is designed for industrial environments where high interference resistance and low data loss are required.

Technology Explained Simply
The switch operates as a Layer-2 device, meaning it forwards data packets based on the MAC addresses of connected devices. Since it is non-manageable, there is no possibility to configure port parameters, VLANs, or QoS settings. Connections are established automatically as soon as a device is plugged in. The use of single-mode fiber optic offers advantages for long-distance transmission, as it exhibits lower attenuation losses compared to multi-mode fiber optic. The SC interface is a standard fiber optic connector that enables secure and easy connections.

Compatibility and Accessories
The switch is compatible with standard Ethernet devices and single-mode fiber optic cables with SC connectors. No specific accessory products are mentioned in the sources that should be combined directly with this model. The use of appropriate fiber optic cables and network cables is required to establish a functional connection.

Mounting and Installation
Mounting is done on a DIN rail, typically found in enclosures or distribution boxes. Installation requires no special tools; the switch is simply clipped onto the rail. Power supply is either via network ports (PoE) or an external power source, although the sources do not provide details on power supply. The IP30 protection rating requires that the device be installed in a protected indoor environment to safeguard against mechanical impacts and foreign objects.

Operational Advantages
The switch provides a reliable and simple network connection for industrial applications without requiring complex configuration. The combination of copper and fiber optic ports allows for flexible network design. DIN rail mounting facilitates integration into existing enclosures. RoHS compliance indicates that the device is manufactured without hazardous materials, which is relevant for environmental compatibility.
