eSSL SA40 — 125 kHz EM + 13.56 MHz Mifare RFID Card Reader (Dual-Frequency Wall-Mount)
10 in stock (can be backordered)
Description
A Pune software firm’s facilities lead inherited a card-based access system with mixed 125 kHz and Mifare cards across 3 floors — finance staff carry old EM cards from the original 2014 rollout, the engineering floor was re-carded with Mifare two years ago when the security audit demanded encryption, and the boardroom floor still uses a separate Mifare batch issued to senior management only. Three card stocks, three reader types at every door, three sets of spare cards in the facilities cupboard. Replacing every reader to standardise on one frequency would mean re-carding 400 staff, retiring usable stock, and dealing with three weeks of access tickets. The eSSL SA40 is built for exactly this. One RFID card reader that reads both EM and Mifare on the same door, Wiegand 26/34 output into the existing access controller — the facilities lead retires three reader SKUs from her spares list without retiring a single working card.
Why integrators specify the eSSL SA40
The eSSL SA40 is the RFID card reader integrators specify when a deployment has to read two frequencies on the same door without dual-reader brackets and without re-carding the whole estate. Dual-frequency support means 125 kHz EM proximity cards and 13.56 MHz Mifare cards both authenticate at the same head, which is exactly what mixed-vintage office buildings need. Wiegand 26/34 output plugs into any standard access controller — eSSL, BioMax or third-party — so the existing access control panel does not need swapping. LED and buzzer feedback gives the cardholder instant confirmation of a successful read, and tamper detection raises an alarm if the reader is pulled from the wall.
RFID technology & read range
The eSSL SA40 operates on dual 125 kHz EM + 13.56 MHz Mifare frequencies with a read range of 5-10 cm — close enough to require an intentional tap (so the reader does not trigger on someone walking past with a card in their pocket), far enough that staff can present the card through a wallet or a lanyard sleeve without removing it. EM 125 kHz handles the older proximity card stock issued years ago, while Mifare 13.56 MHz reads the encrypted cards added during the security upgrade. Both frequencies share the same access control credential path, which simplifies admin: one user record, one card number, one access permission set per cardholder regardless of which card stock they carry.
How it integrates with your access controller
The eSSL SA40 RFID reader outputs Wiegand 26/34, the universal access control reader protocol. It plugs directly into any eSSL, BioMax or third-party access controller that accepts Wiegand input — no protocol converter, no special cable, no proprietary panel lock-in. Run a standard 4-core cable from the reader head to the controller for power, ground and the two Wiegand data lines. The card reader does not need any IP address, software install or firmware push; the access controller manages the credential database and the SA40 is a sensor that converts a card tap into a Wiegand stream. RS485 or TCP/IP integration with the controller is the controller’s job, not the reader’s.
Daily operation
The eSSL SA40 mounts on a standard wall-mount footprint beside the door frame. Power is 12V DC, drawn from the access controller’s reader power supply over the same cable as the data lines. LED feedback confirms a successful card read; buzzer feedback gives an audible cue for blocked staff. Tamper alarm wires back to the controller’s input so the security team sees an event if the reader is forced off the wall. There is nothing to log into, nothing to back up — the eSSL SA40 RFID card reader is a head-end credential sensor and the access control system handles everything else.

What integrators usually ask before ordering
Will it work with our existing access controller?
Yes — the eSSL SA40 outputs standard Wiegand 26/34, which every mainstream access controller accepts. eSSL, BioMax, third-party panels — all of them treat the SA40 as a generic Wiegand card reader.
What’s the read range, and does it work through wallets/lanyards?
Read range is 5-10 cm. Staff can tap with the card inside a slim wallet or a lanyard sleeve; thick wallets with metal-foil RFID-blocking liners will need the card pulled out.
Can it read multiple card types (EM + Mifare)?
Yes — that is the SA40’s purpose. The card reader auto-detects 125 kHz EM proximity cards and 13.56 MHz Mifare cards on the same read head and passes a Wiegand string for both.
Is it IP-rated for outdoor mounting?
The eSSL SA40 is rated for indoor and semi-sheltered mounting. For fully exposed outdoor gates, consider the eSSL KR500-E (IP65) instead.
Does it support encrypted cards?
Yes — Mifare 13.56 MHz cards in this RFID card reader are read with their card serial number; the SA40 supports the standard Mifare CSN flow that most access control deployments use.
