TS-7500 Track Switch

AMR’s Track Switch Monitor (TS-7500) is designed to detect a
gap in rail track-switch. Once installed, the monitor has the
ability to indicate if a track-switch is completely closed, or if it
has a gap of 1/8th inch or more. The TS-7500 consists of a base
unit enclosed in a rugged polycarbonate housing with a clear
light dome and a cylindrical sensor mounted in the track rail. Its
functionality includes a flashing LED strobe that indicates the
status of the track-switch, and a small pulsing amber LED with
buzzer which are used as low-battery warning devices. The unit
is powered by a lantern style 12VOC battery or the unit can be
AC powered.
