L410-W Wiegand RFID access control reader, beige front view with LED window

L410-W Waterproof 125kHz Wiegand 26/34 RFID Access Reader, Resin-Potted

Q: How do I switch the L410-W between Wiegand 26 and Wiegand 34?

Leave the purple wire unconnected for Wiegand 26, which is the default. Connect it to GND for Wiegand 34. No software, programming card or firmware change is needed; set the controller to the same format.

Q: Which cards does the L410-W read?

The L410-W reads 125 kHz EM4100 and TK4100 cards and fobs at 0–100 mm. For MIFARE Classic S50/S70 cards order the H410-W; the D410-W reads both bands (availability confirmed in your quotation). All versions read the card number only and cannot write or copy cards.

Q: How far can the reader be from the controller?

Up to 100 m of Wiegand cable. Use shielded cable and a common ground between reader, power supply and controller; long unshielded runs are a common cause of missed or wrong reads.

Q: Is the L410-W waterproof?

Yes. The electronics are sealed in black resin inside an ABS shell, and the specification describes the reader as waterproof, with an operating range of -25 °C to +75 °C for outdoor doors and gates. No IP rating is published, so we do not quote one. If your project specification requires a rated enclosure, state it in your RFQ.

Q: Will the L410-W work with my access controller?

It works with controllers that accept a standard Wiegand 26 or Wiegand 34 reader and can supply 9–16 V DC at up to 100 mA. Send the controller model with your RFQ and we confirm the format and wiring in your quotation.

The L410-W is a waterproof, resin-potted wall reader for doors and gates that sends EM4100/TK4100 card numbers to access controllers with a Wiegand 26 or 34 input. It reads 125 kHz cards at 0–100 mm, outputs Wiegand 26 by default or Wiegand 34 with one wire change, and runs on 9–16 V DC. The H410-W is the 13.56 MHz MIFARE Classic version.

Frequency: 125 kHz (L410-W); 13.56 MHz (H410-W); 125 kHz + 13.56 MHz (D410-W)
Cards / tags: EM4100 / TK4100 (L410-W); MIFARE Classic S50 / S70 (H410-W)
Interface: Wiegand
Output: Wiegand 26 (default); Wiegand 34 (purple wire to GND)
Read range: 0–100 mm (card and environment dependent)

Why integrators choose the L410-W

Wiegand 26 or 34 by wire — Wiegand 26 is the default; tie the purple wire to GND for Wiegand 34, with no programming card or software.
Waterproof resin-potted housing — the electronics are sealed in black resin inside the ABS shell, which the specification describes as waterproof, with an operating range of -25 °C to +75 °C. No IP rating is published.
Three frequency versions — L410-W for 125 kHz EM4100/TK4100, H410-W for 13.56 MHz MIFARE Classic S50/S70, and D410-W for both bands (availability confirmed in your quotation).
Long controller runs — Wiegand data travels up to 100 m to the controller over shielded cable.
Clear user feedback — reads in under 200 ms; the LED changes from red standby to green with a beep, and the gray wire lets the controller drive LED and buzzer.
Low current draw — 0–100 mA at 9–16 V DC, so it can usually run from a controller's 12 V reader output.

Wiring the L410-W to an access controller

The L410-W has a 180 mm lead with six color-coded wires. Connect it to the controller's reader port over shielded cable with a common ground; Wiegand runs of up to 100 m are supported.

Wire	Function
Red	VCC, 9–16 V DC
Black	GND
White / Green	Wiegand data D0 / D1 (assignment confirmed with your order)
Gray	Green LED and buzzer control
Purple	Format select: open = Wiegand 26, to GND = Wiegand 34

If the controller logs nothing, or a number that does not match the card, the data lines are usually swapped or the two ends use different Wiegand formats. Swap D0 and D1, or change the purple-wire setting. The Wiegand wiring guide covers grounding and cable faults.

L410-W, H410-W or D410-W: match the reader to your cards

The three versions share the potted housing, wiring and Wiegand output. Only the card frequency changes, so choose by the credentials already issued on site.

L410-W, 125 kHz — EM4100 and TK4100 proximity cards and key fobs.
H410-W, 13.56 MHz — MIFARE Classic S50 (1K) and S70 (4K) cards. The reader sends the card UID only.
D410-W, 125 kHz + 13.56 MHz — for sites moving from EM cards to MIFARE, where both card types must open the same door during the changeover. Availability is confirmed in your quotation.

All versions are read-only. Permissions live in the controller, so enrolling a card means registering its number there. If you are still choosing a card technology, read 125kHz vs 13.56MHz first.

What the controller receives

In Wiegand 26 the reader sends 24 data bits between two parity bits: an 8-bit facility code (0–255) and a 16-bit card number (0–65535). Wiegand 34 sends 32 data bits between two parity bits. Set the controller to the same format as the reader.

The format decides how much of the card ID reaches the controller. An EM4100 card carries a 5-byte ID; Wiegand 34 sends the last 4 bytes and Wiegand 26 the last 3. For the ID 3A 00 9C 5E 41, the 10-digit number printed on many cards is 0010247745 (last 4 bytes), while a Wiegand 26 controller receives facility 156 and card 24129, often printed as 156,24129. On the H410-W, Wiegand 34 carries a whole 4-byte MIFARE Classic UID and Wiegand 26 carries 3 of its 4 bytes. Use the Wiegand 26/34 calculator to check that the number printed on a card matches what the controller logs.

Integration in 4 steps

1
Mount the reader on the wall or pillar next to the door and run shielded cable to the controller, keeping the Wiegand run within 100 m.
2
Connect red to the 12 V reader supply (9–16 V DC accepted), black to GND, and the white and green data wires to the controller's D0 and D1 terminals, with a common ground.
3
Leave the purple wire open for Wiegand 26 or connect it to GND for Wiegand 34, matching the format set in the controller. Connect gray to the controller's LED/buzzer output if you want it to signal access granted.
4
Present a card: the LED turns green and the buzzer sounds. Register the logged number in the controller software; if it looks wrong, swap D0 and D1 or check the Wiegand format.
