Trains or Subways are valuable and the major means of transportation but these high-speed trains can be very dangerous at the same time.
That’s way it’s necessary for railway traffic control systems to have reliable and precise train detection technique to keep safe at relevant places such as railway stations, train waiting room, underground facilities, railway crossings, etc.
Needs
But, detecting a train is not easy.
Detecting a train is not so easy task technically, because a train vehicle has a lot of noises from high voltage, AF communication noise, external spikes, etc.

Unique Technology
RA-301 is an innovative synthetic sensor that internally composed of 2 sensor of magnetic and integral proximity sensor to detect train or subways on railways. It detects only trains and doesn’t make a false alarm for rain or snow.

Installation
It can be used near high voltage lines of train and the installation time of the sensor is just 10 minutes.
RA-301 sensor can be installed on the side of railways. Detection distance is about 30Cm~120Cm between sensor and train.
