LAN Connectors for Railway and Industrial Applications


Interface Connector for Industrial Ethernet Applications

The TJL Series is designed as an ideal choice for widely used Industrial Ethernet applications. It supports the on-site information wiring system, JIS X 5150 (ISO/IEC 11801) Class D (Category 5). Variations are available in a Board mount and relay types. Available in 1 port (4 pos) and 2 ports (8 pos) type.

1. Supports Ethernet
Supports on-site information wiring system, JIS X 5150 (ISO/IEC 11801) Class D (Category 5), and can be used for connecting Ethernet. Additionally, it ensures sufficient creepage distance and withstand voltage of AC1500V between contacts and shield.

2. Withstands vibration and impact
The connector is highly resistant to shock and vibration, and has passed shock and vibration tests for railway vehicles (JIS E 4031 Group 1 Grade B).

3. Snap-in lock feature
Snap-in lock design provides easy locking just by inserting the connector. Provides a clear tactile click when fully mated. (Refer to page 3 for details.).

4. Uniform cable strip length to produce
stable transmission performance Unique "2-piece structure" equalizes cable strip length and contributes to stabilizing transmission performance by reducing variations in workmanship.

5. Supports the panel size of 3U4HP
Can be mounted on a 3U4HP panel of a VME rack or a Compact PCI rack.
*One 1-port and one 2-port type can be mounted on one panel (3 ports resp. 12 positions)

6. Incorrect insertion prevention key
By providing an incorrect insertion prevention keying, incorrect inser tion of plugs can be prevented when multiple plugs are used side by side. There are 3 different combinations of the incorrect insertion prevention key available.

7. Cutting terminal
The cutting terminal is widely used in railway markets etc.

8. Available for wire connecting work in the field
The wire crimping type with commercially available hand tools (MIL-compliant products) is suited for field wire connecting work.

9. Selectable cable size
2 different cable sires are supported.
・0.3mm2 (22AWG)
・0.75mm2 (18AWG)

10. Can be temporarily held on the board
Right angle type receptacle can be held on the board before mounting. To fix the receptacle you can choose either screws or rivets.

11. Board thickness
The receptacle supports a board thickness of 1.6mm to 2.4mm.

12. Robust structure
By integrating the panel in between the receptacle body and the hood (supplied item/attached item), the robustness of the installed connector rises.
