LPJE160HENL Tab-Down RJ45 Modular Jack with Green/Yellow LEDs, Industrial Grade

The LINK-PP LPJE160HENL is a ruggedized, single-port (1x1) 8P8C shielded RJ45 modular jack engineered without integrated magnetics (Non-MagJack / direct pass-through). Designed in a space-saving Tab-Down (Latch-Down) orientation with integrated Green and Yellow LED status indicators, it provides a compact depth profile of just 21.30 mm—over 30% shorter than standard MagJack connectors.

Operating reliably across an extended industrial temperature range of -40°C to +85°C, the LPJE160HENL features a 1000V AC dielectric withstand voltage, durable 50 µ-inch gold flash contact plating, and UL 94V-0 flame-retardant thermoplastic housing (UL Certified: File E484635). It is the premier interconnect choice for hardware designs requiring external discrete transformer topologies, high-voltage medical/industrial isolation, or non-Ethernet serial bus interfaces including RS-485, RS-232, CAN bus, DMX-512, and Modbus.

Why Choose a Non-Magnetic RJ45?

While MagJacks dominate standard PC networking, the non-magnetic LPJE160HENL solves critical architectural challenges across industrial and non-Ethernet applications:

1. Non-Ethernet Serial Protocols (RS-485 / CAN / DMX-512) Integrated transformers block DC/low frequencies. The LPJE160HENL allows full pass-through of DC/serial data. 
2. 2High-Isolation Medical / Discrete Magnetics Enables board designers to pair with specialized 4kV~6kV reinforced isolation discrete transformers on the PCB. 
3. Compact 21.30 mm Depth (Space-Constrained Enclosures) Over 10 mm shorter than typical MagJacks (>32 mm depth), drastically reducing front-panel to backplane footprint.

Frequently Asked Questions

Q1: What is the functional difference between LPJE160HENL and an RJ45 MagJack?

A: The LPJE160HENL contains no internal magnetic transformers or choke coils. It is a direct physical pass-through connector. If you are designing a standard 10/100/1000BASE-T Ethernet port with this part, you must place discrete magnetic transformers on your PCB. Conversely, if you are designing RS-485, CAN bus, or proprietary DC systems over RJ45, the non-magnetic design is mandatory to prevent inductive shorting of DC signals.

Q2: What is the exact pin polarity for the integrated LEDs?

A: According to engineering drawing:

• Left LED (Green): Pin 9 is Anode (+), Pin 10 is Cathode (-).

• Right LED (Yellow): Pin 11 is Anode (+), Pin 12 is Cathode (-).

Q3: What is the mechanical significance of "Tab-Down" orientation?

A: "Tab-Down" (or Latch-Down) means that the RJ45 cable plug release latch faces downwards toward the surface of the PCB. This design prevents mechanical interference with upper chassis lips, daughterboards, or display bezels mounted closely above the RJ45 port.

Q4: Is LPJE160HENL rated for harsh industrial environments?

A: Yes. Unlike standard commercial modular jacks rated only for 0°C to +70°C, the LPJE160HENL is fully rated for -40°C to +85°C operating temperatures, features a high-durability contact rating of 750 mating cycles, and carries UL 94V-0 flammability certification (File E484635).
