What an industrial sensor does
A sensor detects a physical input such as light, distance, motion, pressure, temperature or level and turns it into an electrical signal. In automation that signal goes to a PLC, counter or controller, which decides what the machine does next. Sensors are the eyes and ears of every automated line and the first step in collecting data for monitoring and IIoT systems.
Industrial sensors are either discrete, giving an on or off signal when a target is present, or analogue, giving a continuous value such as 4 to 20 mA or 0 to 10 V. Some, like ultrasonic and photoelectric types, can be active and emit their own signal; others respond only to the environment.
As industrial sensor suppliers in India we help you choose the sensing principle first, then the brand and model.
Types of industrial sensors we supply
Photoelectric sensors
Through-beam, retro-reflective and diffuse sensors for detecting objects at a distance.
Inductive proximity sensors
Non-contact detection of metal targets at short range; robust in oil and dust.
Capacitive sensors
Detect non-metal materials such as plastic, powders and liquids through container walls.
Ultrasonic and laser distance sensors
Measure distance or level regardless of colour or transparency.
Colour and mark sensors
Detect print marks and colour contrast for registration on packaging and printing lines.
Pressure, level and flow sensors
Monitor process values in pumps, tanks and pipelines.

How an enquiry works
Send your requirement
Share the sensor 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 PNP and NPN sensor outputs?
A PNP (sourcing) sensor switches the positive supply to the load when it detects a target; an NPN (sinking) sensor switches the load to 0 V. The PLC input must match: sinking inputs need PNP sensors and sourcing inputs need NPN. PNP is more common in India and Europe.
Inductive or capacitive proximity sensor: which do I need?
Use an inductive sensor for metal targets; it is robust and unaffected by dust or oil. Use a capacitive sensor to detect non-metals such as plastic, wood, granules or liquids, including level through a non-metal tank wall. Capacitive sensors need careful sensitivity adjustment to avoid false triggers.
Which photoelectric sensor type has the longest range?
Through-beam sensors, with separate emitter and receiver, have the longest range and most reliable detection. Retro-reflective sensors use a reflector and need wiring on one side only. Diffuse sensors detect light reflected from the target itself, so range depends on target colour and surface.
How do I detect transparent bottles or film?
Standard diffuse sensors struggle with clear objects. Options include retro-reflective sensors designed for transparent targets, ultrasonic sensors that ignore transparency, and capacitive sensors at short range. Share the material and speed and we will suggest a suitable sensor. Line speed and container shape also affect the choice, so include them in your enquiry.
What is IO-Link?
IO-Link is a point-to-point digital communication standard for sensors and actuators. Through a standard 3-wire cable it carries the switching signal plus measured values, diagnostics and parameters, so sensors can be set up and monitored from the PLC. It needs an IO-Link master module. Settings can be stored in the master and downloaded automatically when a sensor is replaced, which shortens maintenance time.
Do you supply sensor cables and connectors?
Yes. We supply M8 and M12 connector cables and sensor connectors along with the sensor, including Baumer and Phoenix Contact cabling items listed on our shop. Tell us the connector type, pin count and cable length. Moulded cables come in PVC or PUR jackets and in straight or angled versions.
