A detector is an essential part of the Dwarvin Integrated RR Crossing system.

This detector makes detection of locomotives or rolling stock easy and reliable.  Just place the sensor where its invisible light beam will reflect off the object of interest and you're done - no time-consuming or frustrating adjustments!  Based on modern silicon technology, this reflective infrared proximity sensor is tolerant of ambient (background) lighting conditions, be it completely dark or under full lights, with no false triggering.  Combined with a discrete under-track installation, this low-profile sensor solves many of the challenges that plague other optical detector products

Once a train or carriage goes over the sensor, it reflects the light down into an integrated sensor.  This is an all-in-one detector system which does not require separate transmitters and detectors to be mounted at peculiar angles to make it work. The Detectors stay on as long as they "see" an object.

Electrical Connections:

It is designed to be used with the Lamplighter® DFL (Dedicated Flasher).  The detector comes with a QWIIC connector attached to 8ft of wire.  Just plug the output from the unit (the white wire) into the trigger port on the Lamplighter DFL unit, and the power (red and black) into the power output on the DFL unit.

Multiple detectors can be added to the Lamplighter DFL unit  You can mix and match this Vertical detector with Side-on ones.

Note that this detector can be used in combination with with other detectors on the same layout and all plugged into the Lamplighter DFL unit.

The Vertical IR Detector is compatible with all model train gauges.  It is elegantly simple to mount and operate.  It mounts underneath the rails using small drill holes, see the diagram below.
