Product size: 41 x 10 x 10 mm <br />Detection distance: about 2 cm when detecting white paper， detecting distance depending on the color， white is the farthest <br />Supply voltage: 2.5V ~ 12V， do not exceed 12V (Note: It is best to use a low voltage power supply， if the power supply voltage is too high， the service life becomes shorter. 5V power sensor is better.)<br />Working current: 18 ~ 20ma when 5V. After extensive testing， the sensor hardware is set to 18 ~ 20ma operating current for optimal performance， mainly indicated in the anti-jamming capability <br />Output electrical level signal: Low level when detecting objects/ high level when no objects <br />Sensor output TTL level can be connected directly with the 3.3V or 5V MCU IO port <br /><br />1 x Line Hunting Sensor  <br />In anti-static bag<br /><img src="http://img6.eachbuyer.com/x9/p100/eb3753_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb3753_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb3753_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb3753_4.jpg" />
