Encoders are widely used in industrial machinery, computers, automation, vehicle speed control, robotics, navigation systems and other equipment. They are also used in data storage, control and measurement systems. Capable of accurately sensing movement, their applications range from general purpose counters to high-resolution position encoders.

The ENA1J-B20-L00128L is an incremental encoder providing digital quadrature output signals, for use in applications requiring angle measurement, speed and direction sensing, or other types of counter operations. It is widely used in various motor feedback applications, motion control, and robotic sensing systems. This encoder\'s built-in optical pickup unit uses 4 sensors in a quadrant pattern to detect the rotation of the encoder shaft.

The optical pick up unit of the ENA1J-B00-L00128L consists of 4 emitters and 4 receivers arranged in a single, four-quadrant formation. This allows the encoder to detect a single rotation or a continuous number of rotations. As the encoder shaft rotates, it passes through the quadrant, causing each emitter and receiver to be separated or combined for each 90-degree increment. The encoder senses this binary transformation and converts it into a digital signal, producing two square wave digital signals, Output A and Output B, which are 90° (¼ cycle) out of phase. This quadrature digital output can be used by an embedded system to determine the speed, distance and direction of rotation.

The ENA1J-B20-L00128L is designed to give high performance, reliability and resistance to electrical interference. It is also designed to deliver high accuracy and durability. The encoder\'s robust construction uses a heavy-duty shaft, sealed ball bearings, and a rugged housing, which all contribute to the high durability of the device. With an extended range of temperature stability, the encoder can be used in a wide variety of applications.

The ENA1J-B20-L00128L is an ideal and cost-effective choice for motor feedback applications, motion control, and robotic sensing systems that require precise angle measurement, speed and direction sensing, or other types of counter operations. The encoder is also well-suited for applications such as automated equipment, machine tools, LED sign boards, and digital photo frames.
