Eltra

Eltra is an Italian company active in the field of industrial measurement technology and electronic analysis systems. The company has a wide product range that includes both rotary encoders for position and speed measurement and specialized electronic measurement and analysis systems. Eltra products are used in various industrial applications where precise position measurement, angle and speed measurement or material analysis is required.

The Eltra EH series rotary encoders are compact incremental encoders used for precise measurement of rotational position and speed in industrial machines. These encoders generate electrical pulse signals proportional to the rotational position of the shaft. The EH series is available in various resolutions (from 100 to more than 5000 pulses per revolution) and connection versions (RS422, Push-Pull, NPN/PNP output) for compatibility with various PLC and control systems.

Eltra also produces specialized analysis systems based on combustion technology for measuring carbon, sulfur, nitrogen and other elements in solid, liquid and gaseous samples. The EMIA series and other Eltra analysis equipment are used in metallurgical laboratories, steel companies and quality control laboratories for precise material quality control.

The heating element products from Eltra (space heaters, tube and hose heaters) form another part of the product program. These heating elements are used in industrial ovens, heat treatment installations and electric heating systems for various industrial applications.

Verkopershulp.nl supplies various Eltra products, including rotary encoders (EH series), analog and digital sensors, heating elements and accessories. For specific Eltra measurement equipment and analysis systems, Verkopershulp.nl offers technical advice and project support.

Frequently Asked Questions

Which Eltra encoder resolutions are available at Verkopershulp.nl?
Verkopershulp.nl supplies Eltra incremental encoders in resolutions of 100, 200, 250, 360, 500, 512, 1000, 1024, 2000, 2048, 2500 and 5000 pulses per revolution (PPR). The available resolution depends on the encoder model. For absolute encoders, various bit resolutions are available. Contact us for the available configurations.
Are Eltra EH series encoders compatible with Siemens and Allen-Bradley PLC systems?
Yes, Eltra EH series encoders are available with various signal outputs, including RS422 differential (compatible with most industrial PLC counters), Push-Pull (5-24V), NPN open-collector and PNP outputs. This makes them compatible with Siemens SIMATIC, Allen-Bradley ControlLogix, Schneider Electric and most other industrial PLC platforms. Verkopershulp.nl advises on the correct output configuration.
What is the maximum shaft speed for Eltra rotary encoders?
The maximum mechanical speed of Eltra EH series encoders is typically 6000-12000 RPM, depending on the encoder model and shaft diameter. The maximum electrical output frequency is determined by the combination of resolution (PPR) and rotation speed (RPM). Verkopershulp.nl can provide the specifications per model for your specific application.
Are Eltra encoders available in versions for humid or chemical environments?
Eltra encoders are standard available in protection class IP65 and IP67. For applications with aggressive chemicals, humid environments or high-pressure cleaning, special stainless steel versions or encoders with increased IP class are available. Verkopershulp.nl advises on the correct version for your installation environment.
Does Verkopershulp.nl also supply replacement cables and connectors for Eltra encoders?
Yes, Verkopershulp.nl supplies connection cables and connectors for Eltra encoders. Provide the encoder model and the desired cable length and connector type (M12, M23 or Sub-D) for the fastest delivery of the correct cable. We can also supply individual cable sets for connecting Eltra encoders to various PLC and frequency inverter inputs.
What is the difference between an Eltra incremental and absolute encoder?
An incremental Eltra encoder generates a pulse signal proportional to the rotated angle and requires a reference position (zero pulse) at startup. An absolute encoder delivers a unique digital code for each angular position, making the absolute position always available, even after power failure. Absolute encoders are necessary when the position must be immediately known after power failure or emergency stop.
What is the delivery time for Eltra encoders at Verkopershulp.nl?
The delivery time for Eltra encoders depends on the specific model and requested configuration. Common Eltra EH series encoders in standard configurations are often directly available from our European stock with a delivery time of 1-5 working days. For special configurations or less common models, the delivery time may be 2-4 weeks.
