Patlite is a global leader providing visual and audible signaling solutions for industrial environments. Understanding how to read and decode Patlite product model numbers not only helps you select the right device but also ensures cost optimization for your system.
Below is a detailed guide to the product model structures for the most common Patlite device series.
How to read the model code of Patlite signal tower lights

Signal Tower Lights are Patlite’s core product line, commonly used to indicate machine operating status. The model code of modular tower lights (e.g., LR, LD, LCE series) follows a general rule describing the series, diameter, number of tiers, voltage, and additional features.
A typical Patlite tower light model number can be decoded as follows:
| POSITION | REPRESENTATIVE CHARACTER (Example) | MEANING |
| Series | LR | Product series (LR: New modular type, LE: Standard) |
| Diameter | LR6 | Diameter (6 = Ø60mm, 5 = Ø50mm, 4 = Ø40mm, etc.) |
| Number of tiers | LR6-3 | Number of tiers (1, 2, 3, 4, 5 tiers) |
| Voltage | LR6-302 | Operating voltage (02: DC24V, 10: AC100V, 220: AC220V, etc.) |
| Mounting | LR6-302L | Mounting type (W: Direct/cable, L: Short pole, P: Long pole, etc.) |
| Function/Buzzer | LR6-302LJ | Special feature (F: Pole-mount, J: With buzzer, N: No buzzer/Blinking) |
| Colors | LR6-302LJ-RYG | Colors of each tier from top to bottom (R: Red, Y: Yellow, G: Green, B: Blue, C: Clear, W: White) |
Example:
- LR6-302LJ-RYG: LR6 series ($\phi$60mm), 3 tiers, DC24V (02), short pole (L), integrated buzzer (J), colors from top to bottom: Red – Yellow – Green.
How to read Patlite signal light model codes

Signal lights are typically single lamps, rotating lights, or flashing lights with simpler model structures.
| Position | Representative Character (Example) | Meaning |
|---|---|---|
| Series | NE | Product series (NE: LED mini, ME: Mini, PES: LED flashing light) |
| Voltage | NE-24 | Operating voltage (24 = 24V DC, M1 = 12–24V DC) |
| Wiring | NE-24AC | Wiring system (None = Cable, C = M12 Connector) |
| Sensor | NE-24ACT | Touch sensor (T = With touch sensor, N = No touch sensor) |
| Buzzer | NE-24ACTB | B = With buzzer, N = Without buzzer |
| Color | NE-24ACTB-M | LED color (R: Red, Y: Yellow, G: Green, B: Blue, C: White, M: Multi-color) |
Example:
- ME-24A-R: ME series signal light, DC24V, Red color.
How to read Patlite alarm/voice annunciator model codes

Patlite sound alarms and voice annunciators are designed to deliver critical alerts. Their model codes emphasize sound level output, melody libraries, and programmability.
| Position | Representative Character (Example) | Meaning |
| Series | EHV | Product series (EHV) |
| Voltage | EHV-M1 | Rated voltage (M1: 12–24V DC, M2: 100–240V AC, M3: 12–48V DC) |
| Wiring method | EHV-M1H | Wiring type (H: Cable, T: Terminal block) |
| Alarm type | EHV-M1HF | Alarm type (F: Type F, G: Type G) |
Example:
- EHV-M2TG: EHV series alarm/voice annunciator, 100–240V AC (M2), Terminal block wiring (T), Type G alarm.
How to read Patlite industrial LED light model codes

Patlite Industrial LED Lights are used for illuminating work areas, especially inside machines or control cabinets. Key model code parameters include length, brightness, and environmental protection ratings.
| Position | Representative Character (Example) | Meaning |
|---|---|---|
| Series | CLA | Product series (CLA: Slim light bar, CLT: Standard light bar) |
| Length | CLA1S | Size/Length (1–12 = 100mm–1200mm) |
| Voltage | CLA1S-24 | Operating voltage (24: DC24V) |
| Brightness/Feature | CLA1S-24-CD | CD: Daylight, C = Amber |
| Cable length | CLA1S-24-H-30 | None = 0.5m, 30 = 3.0m |
Example:
- CLA2S-24-H: CLA slim LED light bar, 200mm length, 24V DC, daylight brightness, 0.5m cable.
