Product Description

Bourns ENT1J-D28-L00128L EN Series rotary optical encoder operates at 5V DC with a resolution of 128 pulses per revolution providing precise position feedback for industrial automation and motion control applications.

This encoder features a solid shaft with 0.25 inch diameter, axial terminal type, and a panel mount design helping facilitate easy installation in control panels and machinery setups.

Constructed with a metal bushing and shaft, it supports high operating speeds up to 3000 rpm and offers a long mechanical life, up to 200 million revolutions for versions with ball bearing bushing.

The optical technology provides a push pull output signal type producing square wave signals that are CMOS and TTL compatible, suitable for digital panel controls and position sensing requiring high reliability and precision linearity.

This encoder includes a 2-bit quadrature output where channel A leads channel B by 90° with clockwise rotation. Its IP40 rating protects against large solid objects, while the operating temperature range from -40°C to 75°C ensures robust performance in industrial environments.

RoHS compliance guarantees environmentally safe manufacturing practices and materials. Mount type is panel mount with axial terminals simplifying integration into existing systems. Typical industrial applications include automation systems, motion control, robotics, and digital position feedback.

Available with a compact overall size of approximately 47.05mm height, 23.37mm depth, and 22.2mm width, this device is ideal for tight installation spaces.

Choose Bourns EN Series Optical Encoders from EnvMart for durable, high-precision rotary position sensing suitable for manufacturing, industrial automation, and electronic control applications.
