ENT1J-D28-L00128L Description

Short technical summary and product information.

The Bourns ENT1J-D28-L00128L is a self-contained rotary optical encoder designed for digital systems requiring precise magnitude and direction sensing. It produces a 2-bit quadrature signal with a resolution of up to 256 PPR, suitable for applications where long life, reliability, and linearity are critical.

 

This encoder operates at a 5VDC supply voltage with a maximum supply current of 26mA. It is compatible with CMOS and TTL logic levels. The encoder offers a useful rotational life of up to 200 million shaft revolutions and supports high operating speeds up to 3000 rpm with a ball bearing option.

 

Designed for panel or PCB through-hole mounting, the ENT1J-D28-L00128L features a vertical orientation and a PC pin termination style. Its compact size makes it suitable for space-limited applications. The encoder provides square wave digital pulses that do not require debounce circuitry, simplifying system integration and reducing memory overhead.

 

This model is RoHS3 compliant and has an MSL rating of 1.
