Industrial sensors for factory automation and maintenance teams
GODOWN is an industrial sensors supplier for factories in Noida, Greater Noida, Ghaziabad, Gurugram and Faridabad, sourcing the sensors that tell a machine where things are: inductive and capacitive proximity sensors, photoelectric sensors, rotary encoders, limit switches, and pressure, temperature and level sensors. One failed sensor can stop a cell, so most plants hold a few as critical spares and buy the rest when a line is down.
The quickest indent is a photo of the old sensor's label with the full part number, tagged to the machine and station. If the exact part is hard to find, an equivalent that matches body size, range, output and connector will usually do, so say on the indent whether one is acceptable.
GODOWN prioritises line-stop requirements, gets you competitive quotes for the exact part or an equivalent, and tracks delivery to your gate with a GST tax invoice. If a sensor is dead on arrival, we handle the return.
Sensors we source for plants
Inductive proximity sensors
Detect metal targets without contact, in M8, M12, M18 and M30 barrels or rectangular bodies. Rated range is for mild steel; aluminium, brass and copper targets are sensed at a shorter distance.
Capacitive proximity sensors
Detect non-metallic materials such as plastic, glass, granules and liquids, including through the wall of a non-metallic tank. Sensitivity is adjustable to suit the material.
Photoelectric sensors
Through-beam types for the longest range, retro-reflective types with a reflector (polarised versions for shiny objects), and diffuse or background-suppression types that sense the object directly.
Rotary encoders
Incremental encoders give a set number of pulses per revolution for speed and position; absolute encoders report position directly and keep it through a power loss. Available with solid or hollow shafts.
Limit switches
Mechanical switches with roller lever, plunger or rod actuators for end-of-travel and position sensing. Safety-rated versions have positive-opening contacts.
Pressure sensors and switches
Transmitters with 4–20 mA or 0–10 V output, and pressure switches, for hydraulics, pneumatics, water and process lines. Specified by range and process connection.
Temperature sensors
Pt100 RTDs and J- or K-type thermocouples for ovens, moulds, reactors and bearings, with or without a head-mounted transmitter.
Level sensors
Float switches, vibrating forks, capacitive probes and ultrasonic sensors for tanks, hoppers and sumps.
Safety light curtains
Type 4 light curtains guard presses and robot cells. Resolution sets what they detect: 14 mm for fingers, 30 mm for hands.
What to put on a sensors indent
Vendors quote the right part first time when the indent carries these. Missing details mean a round of calls before anyone can quote.
- Part number and photo: the full code from the old sensor's label, plus a photo of how it is mounted.
- Body and range: barrel size (M12, M18, M30) or rectangular dimensions, rated sensing distance, and flush (shielded) or non-flush mounting.
- Output: PNP or NPN to match the PLC input card, NO or NC, 2-wire or 3-wire, or analogue 4–20 mA or 0–10 V. Add IO-Link if the machine uses it.
- Supply voltage: 10–30 V DC for most DC sensors, or the AC/DC range for 2-wire types.
- Connection: M8 or M12 connector with pin count, or pre-wired cable length. PUR cable for coolant, oil and cable chains; PVC for dry areas.
- Environment: IP67, IP68 or IP69K, operating temperature, weld-field immunity for welding cells, and stainless-steel housings for food and pharma wash-down.
- Encoders: incremental or absolute, pulses per revolution or resolution, output (TTL line driver, HTL push-pull or a fieldbus), shaft or hollow-shaft diameter, and flange.
- Process sensors: range, output signal, process connection (such as 1/4 inch BSP), wetted material and the medium being measured.

Where it's used in a plant
- Machine tools and assembly stations: part presence, clamp confirmation and end-of-stroke sensing on fixtures and cylinders.
- Conveyors and packaging lines: photoelectric product detection, encoders for speed and length, and level sensing on hoppers.
- Press shops and robot welding cells in auto component plants: weld-immune proximity sensors and safety light curtains at loading points.
- Process plant: pressure, temperature and level on reactors, dryers, tanks and boilers.
- Utilities: pressure switches on compressors and pumps, and temperature sensors on chillers and cooling water.

Buying sensors: common questions
What is the difference between PNP and NPN sensors?
A PNP sensor switches the positive supply to its load, so it sources current; an NPN sensor switches the load to 0 V, so it sinks current. They are not interchangeable without changing the wiring or the PLC input card. Machines built to European practice mostly use PNP, while many Japanese and other Asian machines use NPN. Read the type from the old sensor's label and put it on the indent.
Can I replace a proximity sensor with another brand?
Usually, yes. A replacement works if it matches the body size, rated sensing distance, flush or non-flush mounting, output type (PNP or NPN, NO or NC), supply voltage and connector. Check switching frequency on fast machines, and parameters on IO-Link devices. Safety-rated sensors and light curtains are different: a change of model means the safety function has to be re-validated, so specify the exact part for those.
How do I get a sensor fast when a line stops?
Raise the indent as urgent, with a photo of the old sensor's label and the machine it belongs to; GODOWN prioritises requirements that have stopped a line. Say whether an equivalent is acceptable, since that widens the choice. The lasting fix is to keep one or two of every sensor that can stop a line on your store shelf, so most failures are solved by a store issue rather than a purchase.
What do IP67 and IP69K mean for sensors?
Both describe protection against dust and water. IP67 means dust-tight and protected against temporary immersion, tested at 1 metre for 30 minutes. IP69K adds protection against close-range, high-pressure, high-temperature wash-down, which is why it is specified on food and pharma lines cleaned with hot water jets. IP68 covers continuous immersion under conditions the maker states. Choose the rating for how the machine is cleaned.
