Wi-Tek - WI-PS305G-F-M12 - Flat-type Unmanaged Switch

Product Overview

The Wi-Tek WI-PS305G-F-M12 is an industrial EN50155 M12 Gigabit PoE switch designed for rail transit, vehicles, trackside systems, and other applications exposed to vibration and shock. It provides four M12 X-code Gigabit PoE+ ports and one M12 X-code Gigabit uplink port, with up to 30 W per PoE port, redundant 48–56 V DC power input, and a compact fanless enclosure for harsh environments.

Key Configuration

Model: WI-PS305G-F-M12 | PoE Ports: 4 × M12 X-code Gigabit PoE+ ports | Uplink Port: 1 × M12 X-code Gigabit port | PoE Standard: IEEE 802.3af/at, up to 30 W per port and 120 W total | Power: Redundant dual 48–56 V DC input through a 5-pin M12 A-coded connector | Protection: -40°C to 75°C operation, surge, ESD, overload-current, and reverse-polarity protection

Key Features

• · Four M12 X-code Gigabit PoE+ ports support industrial network devices
• · One M12 X-code Gigabit port provides an uplink connection
• · PoE ports 1–4 comply with IEEE 802.3af/at standards
• · Delivers up to 30 W per port with a maximum 120 W PoE power budget

Technical Context

The M12 X-code connectors provide secure Gigabit data and PoE connections that are suitable for environments exposed to vibration and shock. Store-and-forward switching supports reliable packet handling, while the redundant DC power design provides an alternative power path for increased supply reliability. The switch supports up to 9 kB jumbo frames and is designed to power compatible IEEE 802.3af/at devices such as IP cameras, wireless access points, and IP phones.

Installation Notes

The WI-PS305G-F-M12 supports DIN-rail and wall-mounted installation and uses front-access M12 connectors for space-limited cabinets. The device is intended for rail transit, vehicle, trackside, outdoor, and industrial installations; keep the operating environment within -40°C to 75°C and connect the redundant DC inputs according to the power system design.
