Manufacturer description

With the use of the Sensor Signal developed by Train Tech you can easily add automatic signalling into your layout in seconds. The signals work by detecting a locomotive, or full train passing by it using a very small infrared sensor built in to the signal base. As soon as the locomotive has passed the sensor the signal changes to red and will stay red for about seven seconds to let the train clear the block. It then reverts back to green.

If more than one signal is being used in a section, such as a distant and home combination, the two signals can be linked by a single wire. This enables a signal sequence to be activated when the train passes the first signal. As the locomotive passes the first sensor the signal changes to red (as before) but as the train passes the second sensor the previous signal reverts to green and the additional signal changes to red which gives fully automatic block signalling, just like the real railway.

If you have multiple aspect signals (3 and 4) the yellows are also incorporated into this sequence. These signals are easy to set up and only require a single wire to link them all together to the sequence.

These signals can be used on both DC and DCC layouts using two methods of installation.

On DCC layouts you just need to connect the base prongs to the underside of the rails (like a power clip) this then enables them to be given a DCC address or run them automatically. To install these signals onto an existing layout you can cut the prongs off at the dotted lines and solder two wires onto the back of the PCB and run the wires to the power Bus Wires.

On DC layouts you need to cut the prongs at the dotted lines and solder two wires onto the base and connect them to a smooth 12V DC power supply. If you do not already have a suitable smooth DC supply then we recommend the GMC-WM4 12V DC Wall Mounted Transformer, which gives great value for money and 1.25 amps of power, enough to power about 20 signals per supply.

The Feather on this signal can be controlled separately by programming it to a different address or by connecting it to a point motor with auxiliary terminals of DC use.

On both DC or DCC these sensor signals can be linked to the Mimic Switches for a manual override to red, control of a route indication and LEDs indicating signal colour and track occupation.

Catalogue listing

Train Tech Sensor Signal (LH Feather) 2‑Aspect Home – part number TTSS1L – is a miniature railway signal that incorporates an infrared sensor to detect locomotives or trains passing the base. When a train passes, the signal changes to red for approximately seven seconds before returning to green, allowing the train to clear the block.

The device can be linked with a single wire to additional signals, such as a distant or home combination, providing an automatic sequence where the first signal turns red and the second reverts to green as the train passes. Multi‑aspect signals (three‑ or four‑aspect) include yellow aspects in the same sequence. All signals require only one wiring connection to operate together.

The sensor signal is suitable for both DC and DCC layouts. On DCC the base prongs can be clipped to the rails for addressability, or the prongs may be cut and wires soldered to a power bus. On DC the prongs are cut and two wires are connected to a smooth 12 V DC supply; a 12 V 1.25 A wall‑mounted transformer such as the GMC‑WM4 is recommended for powering up to twenty signals. The Feather head can be programmed to a separate address or driven by a point motor via auxiliary DC terminals, and the signals may be linked to Mimic Switches for manual red override, route indication and LED track‑occupation indicators.
