A high precision encoder is a device that converts mechanical motion into an electrical signal. It provides accurate position and speed feedback in various applications, ensuring precision, reliability, and consistent performance..

High precision encoders typically use optical or magnetic technology to detect motion and generate electrical signals. These signals are then processed to determine the position and speed of the moving component.

High precision encoders are used across a wide range of industries, including robotics, industrial automation, aerospace, medical equipment, CNC machinery, and many others.

High precision encoders provide accurate and reliable position feedback, which is essential for applications requiring precise motion control. They help improve the overall performance, efficiency, and reliability of machinery.

We manufacture optical incremental encoders with resolutions of up to 10,000 PPR (Pulses Per Revolution), catering to a wide range of industrial applications.

Absolute encoders provide a unique position value for every shaft position, while incremental encoders generate pulses corresponding to changes in position. Unlike incremental encoders, absolute encoders retain position information even after a power loss.

A rotary encoder measures rotational movement, the angle, speed and direction of a spinning shaft, and is used wherever a machine component turns, such as a motor, roller or spindle. A linear encoder measures straight-line movement along a track or scale. JENCODER specializes in rotary encoders, which cover the vast majority of industrial automation applications, from motor feedback to conveyor and machine tool positioning.

PPR, or Pulses Per Revolution, refers to the number of electrical pulses an encoder generates for each complete rotation of its shaft. A higher PPR means finer resolution and more precise measurement of position and speed. JENCODER manufactures encoders across a wide resolution range, from 1 to 10,000 PPR, allowing customers to select the exact precision their application requires, without paying for resolution they don't need.

Encoder lifespan depends on build quality, sensing technology and operating conditions, but well-engineered optical encoders, like those manufactured by JENCODER, are designed for long service life under continuous industrial use. Because our encoders use non-contact optical sensing rather than mechanical contacts, they avoid the wear-related failure points common in lower-quality alternatives. Every unit is individually tested before dispatch to ensure it meets the reliability standards our customers depend on.

Yes. A single incremental encoder can simultaneously provide speed, position and direction feedback to a machine's control system. The same pulse signal that tells a controller how fast a shaft is turning also tells it how far the shaft has rotated, making the encoder a compact, all-in-one feedback solution.

Optical encoders use a light source and a patterned disc to generate position and speed signals, while magnetic encoders use magnetic fields and Hall-effect sensors. JENCODER manufactures optical encoders specifically because of the precision, resolution and reliability they offer: optical sensing delivers higher accuracy at fine resolutions and, unlike magnetic sensing, is completely unaffected by stray magnetic fields in demanding industrial environments.

To recommend the right encoder, our application engineers typically need to know: the type of machine or application, required resolution (PPR), shaft type (hollow or solid) and size, mounting configuration, operating environment (temperature, dust, moisture exposure), and the electrical interface your control system requires. If you're unsure of any of these, our team can guide you through the selection process.

Urgent, small-batch requirements can be fulfilled within One working day, thanks to our efficient in-house manufacturing processes. For custom-engineered encoders or large bulk orders, we work on programmed delivery schedules agreed with the customer in advance, ensuring dependable, on-time fulfilment without compromising on quality or testing rigor.

JENCODER encoders are designed and manufactured entirely in India. Established in 1997 as part of the Jayashree Group, a Pune-based industrial group with roots going back to 1972, JENCODER was built to prove that world-class encoder technology could be engineered indigenously, without compromising on the standards traditionally associated with imported, globally renowned brands. Every encoder is produced, tested and dispatched from our own facility.

Elevator systems typically require hollow shaft encoders designed for direct mounting behind the drive motor, with shock- and vibration-absorbing construction to withstand the mechanical stresses of elevator operation. These encoders provide the precise position feedback elevators need to stop accurately, floor after floor. JENCODER manufactures dedicated encoder models engineered specifically for elevator applications.

Textile machinery, including weaving machines and spinning frames, relies on incremental encoders for precise motion control and synchronization between machine sections. These encoders ensure accurate yarn tension and coordinated movement, which directly affects fabric quality and consistency. JENCODER's encoders are widely used across textile manufacturing applications in India.

Conveyor and material handling systems typically use incremental encoders mounted on motors or intermediate shafts to synchronize speed and position across multiple conveying sections, preventing jams and ensuring smooth item transfer. This is an application area where JENCODER's expertise runs particularly deep, given the Jayashree Group's decades-long history in conveyor safety and motion feedback technology.

For CNC and machine tool applications, resolution (PPR) is critical, since it directly determines machining accuracy and surface finish. Shaft type, mounting configuration, and response speed also matter, since machine tools require encoders that can keep pace with rapid, precise tool movement without lag or signal loss. Our application engineers can help match the right resolution and configuration to your specific machining requirements

JENCODER combines the precision engineering standards traditionally associated with established global encoder brands with the agility, customisation and responsiveness of a dedicated Indian manufacturing partner. Our encoders are built to meet the same exacting expectations as globally renowned brands, manufactured, tested and supported locally, with faster turnaround and more direct technical access than most imported alternatives can offer.

JENCODER incorporates 500 VDC surge protection in accordance with EN 61000-4-5, Class I, ensuring enhanced protection against electrical surges.

It also features closed-loop LED intensity control, which automatically compensates for temperature variations and LED ageing, ensuring consistent optical performance throughout the encoder’s service life

A hollow shaft encoder mounts directly onto an existing shaft (such as a motor shaft) by sliding over it, ideal for compact, direct-mount applications like elevator motors, since it doesn't require separate shaft coupling. A solid shaft encoder, on the other hand, has its own independent shaft that must be mechanically coupled to the application's shaft using a coupling device, offering more flexibility in mounting position and alignment. Our application engineers can advise which configuration best suits your specific machine design.

JENCODER offers a range of environmental protection ratings depending on the encoder series and application. Our industrial encoders are available with protection ratings up to IP67, providing effective protection against dust and water ingress. The exact IP rating depends on the specific encoder model, mechanical construction, connector arrangement, and application requirements.

For demanding applications, we can also discuss customized sealing/protection options based on the customer’s environmental conditions.
