What an encoder does
An encoder is a sensing device that converts motion into an electrical signal a controller can read. A counter, PLC, drive or motion controller uses that signal to work out position, count, speed or direction, and then issues the next command.
Most industrial encoders are optical: an LED shines through a code disc patterned with fine lines, and a photodetector reads the light and dark pattern as pulses. Magnetic encoders use a magnetised disc and sensor instead, and tolerate dirt, oil and vibration better.
As encoder suppliers in India we help you match resolution, interface and mounting to the controller you already use.
Types of encoders
Incremental encoders
Output pulses as the shaft turns; the controller counts them. Simple and widely used for speed and relative position.
Singleturn absolute encoders
Give a unique position value within one revolution, retained after power loss.
Multiturn absolute encoders
Track position across many revolutions without homing, for long-travel axes.
Hollow shaft encoders
Mount directly over a motor or machine shaft without a coupling.
Sin/Cos encoders
Analogue sine and cosine outputs for high-resolution servo and lift feedback.
Linear and draw-wire sensors
Measure straight-line position on cylinders, platforms and gates.

Encoder applications
- Cut-to-length lines using a measuring wheel to tell the controller when to cut
- Printing and labelling, where the encoder triggers the print head at the right point
- Cranes and hoists needing hook position feedback
- Bottle and jar filling lines tracking container position
- Lifts, where feedback stops the car level with the floor
- Robots and welding cells on assembly lines

How an enquiry works
Send your requirement
Share the encoder details, quantity and site location through the quote form, phone or email. A nameplate photo or existing part number speeds things up.
Technical review
We check the ratings and application against available models and come back with questions if anything is unclear or missing.
Options and quotation
You receive suitable options, including equivalents where an exact match is not available, with a written quotation.
Supply and support
After the order we coordinate dispatch to your site in Mumbai or anywhere in India and remain available for spares and follow-up questions.
What is the difference between an incremental and an absolute encoder?
An incremental encoder outputs pulses as the shaft moves, and the controller counts them from a reference point, so position is lost on power failure. An absolute encoder outputs a unique value for every position and keeps it after power loss, so no homing run is needed. Absolute encoders cost more but suit multi-axis machines.
How do I choose encoder resolution?
Divide the distance or angle moved per revolution by the accuracy you need. If a measuring wheel moves 200 mm per turn and you need 0.1 mm, choose at least 2000 PPR. Also check that the controller's input frequency can handle the pulse rate at maximum speed.
What is the difference between TTL and HTL outputs?
TTL (RS-422) outputs are 5 V differential signals that resist noise well over moderate cable lengths and suit drives and motion cards. HTL (push-pull) outputs swing to the supply voltage, typically 10 to 30 V, and suit PLCs and counters with 24 V inputs. Match the output to the controller input.
Hollow shaft or solid shaft encoder?
A hollow shaft encoder slides over the motor or machine shaft and is held by a stator coupling, which saves space and removes the coupling. A solid shaft encoder connects through a flexible coupling and suits mounting on a bracket or measuring wheel. Choose based on available space and shaft access.
Can you supply a replacement for an obsolete encoder?
Usually. Send the label photo showing part number, resolution, output and supply voltage, plus shaft and flange details. We look for the current model in the same series or an equivalent with matching electrical and mechanical interfaces. Include the controller the encoder connects to, because the input type limits which outputs and resolutions will work.
