The New Universal Hex Frog Juicer automatically and instantly switches the polarity of the frog as the engine passes over any DCC powered turnout. No more complicated wiring or electro-mechanical switches are needed. Instead you simply connect power to the Frog Juicer and a single wire to the frog. The Frog Juicer takes care of the rest!

The Universal Hex Frog Juicers will work with any DCC system, including NCE PowerCab!

Only need to switch one or two frogs? Check out the Universal Mono Frog Juicer or Universal Dual Frog Juicer!

Each Hex Frog Juicer can control the polarity of DCC power for up to six frogs on all types of switches including turnouts, wyes, 3-ways, slips, crossings and crossovers. Using a Hex Frog Juicer is especially helpful for double crossovers and crossings as it dramatically simplifies the wiring for these types of switches.

The Hex Frog Juicer can be used to switch the frogs for up to three reverse loops or wyes. (You need to use two frog control outputs for each reverse loop and wye.)

  • Eliminates the need for mechanical switches to switch the frog polarity when the turnout is switched
  • Instant switching means no interruption to the engine or loss of sound
  • Significantly simplifies frog wiring - especially for crossings and double crossovers
  • Compatible with any DCC system (It will not work with DC)
  • Simple to connect

If you have ever struggled with wiring up the frogs on a switch, then you will want to seriously consider using the Hex Frog Juicer. It is simple to use, and just plain works.

How The Hex Frog Juicer Works

The Frog Juicer consists of six microprocessor controlled SPDT electronic switches. Each switch can sense and control the polarity of one frog. When the circuit detects a short greater than about 1.7 amps (plus/minus 10% with 2 amps the upper limit), it instantly switches the polarity of the frog. Two amps is below the reverse polarity detection point for most DCC circuit breakers and booster units so that the Frog Juicer will react before a fault is detected.

In addition, the Frog Juicer switches so quickly that the brief current pulse will go unnoticed by the DCC system.

Two amps is also enough current to power a single locomotive, and since only one locomotive can be on a frog at a time it is all the power that you need. The frogs need to be electrically isolated and have no other connections to the track or DCC system.

What a great device. Used it to replace Tortoise contacts wired to frogs on an n Scale yard lead and eliminated a ton of wiring. Easily installed and best of all, it works as advertised.

The Frog Juicers are a simple method of powering turnout Frogs. Very easy to hook up and work seamlessly. I don't like using them as a reverser. They have a jumper to pair sets of outputs, but it seems to have glitches. For powering a frog, it is ideal.

A reduced overall rating here due to a Canadian business that doesn't have an option to show pricing in Canadian currency. Very disappointed in that. Beyond that though great service from order placement to delivery and appreciate the step by step update of the order status.
