Travel distances of 1 to 5 meters and available resolutions
The resolution is selected when defining the supply reference. The available combinations depend on the route:
| PATH AND RESOLUTION | ||
|---|---|---|
| Route | Available resolutions | Pulses per millimeter |
| 1,000 and 2,000 mm | 0.02 / 0.01 / 0.008 / 0.005 mm/pulse | 50 / 100 / 125 / 200 |
| 3,000, 4,000 and 5,000 mm | 0.04 / 0.02 / 0.01 mm/pulse | 25 / 50 / 100 |
The integrated multiplier circuit increases the number of output pulses. The resolution indicates the offset corresponding to each pulse. It does not equate to absolute measurement accuracy. The declared repeatability is ±0.1 % of the full scale and ±1 count.
Line driver output and PLC connection
The encoder generates square wave signals with channels A and B in quadrature, which allow the displacement to be measured and its direction to be recognized. The channel Z It provides a reference signal. Each channel has its complementary signal to form the differential pairs. A–/A, B–/B and Z–/Z.
To connect it, the PLC, counter, or data acquisition equipment must have inputs compatible with the line driver and the application's pulse frequency. The sensor's power supply is selected from 5 VDC (L) and 8–26 VDC (H); This supply voltage should not be confused with the electrical level that the controller input accepts.

- Electric wire: 1,000 mm in length and 4.5 mm in diameter.
- Typical lifespan: greater than 1 million cycles.
- Shock: 50 g for 11 ms.
- Vibration: 10–55 Hz, 1.5 mm VPP and maximum 10 g.
IP64 protection and operating conditions
The DLE-HR has IP64 protection and supports operating temperatures of 0 to 60 °C, with relative humidity of 35 to 90 %, non-condensing. The storage temperature is −20 to +70 °C.
DLE-HR references and version selection
The part number identifies the travel, resolution, power supply, and integrated multiplier. The suffix L corresponds to 5 VDC and H 8–26 VDC. Both options use differential line driver output.

Frequently asked questions about the DLE-HR
Is the 0.005 mm/pulse resolution available at 5 meters?
No. It is offered at 1 and 2 m distances. At 3, 4 and 5 m, the finest resolution available is 0.01 mm/pulse.
Does a resolution of 5 µm equate to an accuracy of 5 µm?
No. It expresses the displacement corresponding to an output pulse. Resolution and repeatability are distinct characteristics.
Is it an absolute position sensor?
No. It's incremental: the control system obtains the displacement by counting pulses. The Z signal is an encoder reference and does not turn the equipment into an absolute sensor.
What data is needed to select a reference?
The travel distance, the desired resolution, the speed of movement, the available power supply, and the characteristics of the PLC or counter input.
How does it differ from the DLE-S?
The DLE-HR extends travel distances up to 5 meters and offers finer resolutions through integrated multiplication, a differential line driver output, and IP64 protection. DLE-S with 1,000 mm wire encoder It is another option in the range for one-meter journeys.
