Encoder with wire is a sensor that can determine object linear movement with help of special rope.
Rope encoder design and principle of operation
The main design feature of such sensor is a reel on which rope is wound. This part is connected to own shaft. Movement is transmitted between elements through a mechanical coupling. This system allows rotating shaft on sensor by pulling rope out of reel. Company manufactures wire encoders of both incremental and absolute type.
Performing of such a work requires a very strong and reliable rope. Eltra s.p.a. uses cable type Dyneema in its encoders. It consists of high-strength, high-density material (ultra high molecular weight polyethylene).
Durable materials of entire construction allow device to be used in harsh environments. This appliance is widely operated in many industries.
It is most often used in:
- warehouse systems, etc.
This is possible due to excellent wire strength and whole system mechanical stability. Housing is made of aluminum.
Eltra string encoders series
The Italian company produces wire encoders type in two series:
In general, they are similar, but each have their own design features.
FE - this is a rope encoder’s series designed specifically for linear measurements. Maximum available free rope length is 4m. Series devices available in both incremental and absolute variations.
There are two options of the reel length for eltra encoders:
The second number indicates maximum stroke in mm. Such series will perfectly show itself in harsh conditions, thanks to all elements strength. The end of the cable has a form of an eyelet.
It is important to know that the encoder, which you want to turn into FE, needs to be ordered in separate order.
The letter F is added to beginning of ordering code means that such encoder has its own rope.
The second series of presented rope encoders is FES. It also consists of several devices types with different operation principle. The maximum possible length here is significantly different and reaches 15m. Design also consists of high-strength materials and can be used in the harshest conditions.
There are several options depending on the possible stroke length in eltra wire sensors models:
- FES 3000.
- FES 6000.
- FES 15000.
As in the previous series, the numbers also indicate cable length in mm. Series models are equipped with a horizontal output.
In general, a cable-type device is a very reliable and durable. It is capable of measuring object linear movement at long distances.
