Reads shiny, etched and damaged codes on electronics lines
The BS511 Series is TVS Electronics' wired high-performance handheld scanner for industrial and electronics manufacturing. TVS's product page writes it as 511 Series and its brochure as BS-511 Series. TVS lists three decoding versions: XD (ultra-high density), HD (high density) and SR (standard range). TVS's brochure describes a wired scanner and gives wired figures only; the product page title also says BT, so we confirm any Bluetooth model in the quotation.
Clear reads on shiny parts
TVS says the optical design eliminates polarized light, which prevents overexposure and ghosting. That is its answer to reading problems on highly reflective metal, glass and ceramics.
Reads etched, low-contrast and damaged codes
TVS says multi-spectral technology and a smart algorithm read vague, damaged and low-contrast barcodes, and choose the light source by itself for codes made by laser etching, chemical etching or dot engraving. TVS rates contrast down to 15%.
Small codes on electronics lines
TVS's table gives scanning accuracy of 3 mil and above. TVS also says NPU acceleration and its decoding algorithm are optimised for electronics manufacturing and read ultra-miniature barcodes as small as 1.667 mil. The XD version reads a 3.33 mil Code 128 from 0.5 cm to 3 cm.
A version for each code size and distance
XD reads the smallest codes up close. HD reads a 3.33 mil Code 128 from 2.5 cm to 14 cm. SR reads a 10.83 mil Code 128 from 2 cm to 50 cm and a 20.83 mil QR code from 4 cm to 95 cm.
Keeps up with moving codes
TVS rates motion tolerance at 2 m/s on a 13 mil UPC, and up to 8 m/s in high motion tolerance mode. The light adjusts by itself to different materials, shapes and colours.
Takes drops on the floor
Multiple drops to a concrete floor from 1.8 m, in a PC + ABS housing that TVS describes as IP-rated. TVS's specification table gives no IP number, so we confirm it in the quotation.
These are the points buyers in India ask us about the BS511 Series. Mention the ones that apply to you when you request a quote.
Made in India
TVS Electronics describes its enterprise range as Made in India.
Send the code size and the reading distance
The version decides what reads and from how far. Tell us the smallest code you scan, the material and how far the operator stands, and we match XD, HD or SR to it in the quotation.
Wired: USB or RS232 to your line PC
TVS lists USB-HID, USB-CDC and RS232, at 4.5 V to 5.5 V DC, 175 mA typical and 460 mA maximum. Tell us which port your station uses; the serial cable is an optional accessory.
Need Bluetooth? Say so in your enquiry
TVS's page title reads Wired/BT, but its page and brochure give no Bluetooth range or battery figure for this series. Ask for the Bluetooth model by name, and we confirm its details in writing before you order.

Exploring for a different use?
If your job differs from what the BS511 Series is built for, these TVS models may fit it better:
Buyers who need a scanner TVS states for DPM codes, down to 6% contrast, often look at the
TVS BS512 Series (Quad-core AI decoding, IP67, wired or Bluetooth 5.0).
Buyers who work on a harsh floor with oil, dust and hard drops, often look at the
TVS BS513 Series (Ultra-rugged DPM scanner, IP68, multiple 3 m drops).
What is the price of the TVS BS511 Series in India?
The BS511 Series price depends on the cable or accessories you need and the quantity. We do not publish prices: share the model, quantity and city, and we send a written quotation with current pricing and
delivery time, replying within one working day.
Which version do we need: XD, HD or SR?
XD for the smallest codes read up close, such as a 3.33 mil Code 128 from 0.5 cm to 3 cm. HD for dense codes at a little more distance, the same code from 2.5 cm to 14 cm. SR for labels further away, such as a 20.83 mil QR code from 4 cm to 95 cm. Tell us the code size and the distance, and we suggest the version.
Does the BS511 read DPM codes?
TVS says it reads codes made by laser etching, chemical etching or dot engraving, but its BS511 page and brochure do not use the term DPM. For a scanner TVS itself states for Direct Part Marking (DPM), see the BS512 Series and the BS513 Series. Tell us the mark and the material, and we confirm the right model in the quotation.
Will it read codes on shiny metal, glass or ceramics?
TVS says yes: the optical design eliminates polarized light, which prevents overexposure and ghosting on reflective surfaces. The result depends on your code and your surface, so tell us the material and the code size when you ask for a quote.
Is the BS511 wired or Bluetooth?
TVS's brochure calls it a wired scanner and its figures are for wired use: USB-HID, USB-CDC or RS232. TVS's product page title reads Wired/BT, but neither document gives a Bluetooth range or battery figure. If you need Bluetooth, ask for it in your enquiry and we confirm the model in writing.
Can we get the datasheet?
Yes. Download TVS's BS-511 Series brochure from TVS's website; the link is under the specifications. We confirm the version and the connection in writing in your quotation.
Can Allmark install the BS511 Series and connect it to our software?
Yes. We install the BS511 Series at your site, set it to send data the way your ERP, warehouse or billing software expects (our own warehouse management system included) and train your team. Tell us the software when you ask for a quote, and we include the setup in the quotation.
