F249 Infrared Motor Speed Sensor Module

F249 Infrared Motor Speed Sensor Module Widely used in motor speed detection, pulse count, the position limit, etc. The DO output interface can be directly connected to a micro-controller IO port, if there is a block detection sensor, such as the speed of the motor encoder can detect. DO modules can be connected to the relay, limit switch, and other functions, it can also with the active buzzer module, compose alarm.

Technical Specification:

• Dimensions: 32 x 14 x 7mm.
• The sensor reading slot has a width of 5mm.
• Two outputs, one Digital and one Analog.
