Using the proven benefits of Hybrid Track Technology and including a number of unique design features, the SLS130 displacement sensor is ideally suited to high volume OEM manufacturers, where high performance and reliability with competitive pricing and rapid despatch has paramount importance.

Hybrid track

The hybrid track comprises a high resistivity conductive plastic film bonded to a precision wire-wound element. The conductive plastic film is wiped by a precious metal contact. The technology provides infinite resolution and a very long life (since the majority of the current still flows in the wire, the carbon content of the conductive plastic film is low, and the film is therefore very hard). Track linearity is very good, temperature coefficient of resistance is low and predictable and resistance stability with change in humidity is excellent. 

Options

Compact shaft: Compact shaft will reduce dimension D by 25mm
Integral shaft seal - IP 66: Designed to accept integral shaft seal to give IP66 rating
Extended cable length: 10m output cable can be specified
Mounting: Body clamp, flange or quick release balljoint mounting kits can be supplied
Protective sleeve: For all stroke lengths - self aligning bearings only. See ordering code
Spring loaded shaft kit: For stroke lengths 25 to 150mm with /L shaft option and /50 sealing option only

UK Stock Availability

Displacement Sensors

A displacement sensor is a gauge that measures the distance, height, width, and thickness between a sensor and an object. It transforms mechanical motion into a variable electrical signal (current or voltage). At Curtiss Wright, we provide a selection of displacement sensors suitable for various applications, depending on their environment.

How does a laser displacement sensor work?

Displacement sensors work by converting changes of light into electrical signals when the object intersects a laser beam. There are typically two categories of displacement sensors: non-contact and contact sensors. Non-contact use light, magnetic fields, or sound waves to measure the distance or contact sensors. In contrast, contact touches the target to measure the distance. 

The method of triangulation is applied in non-contact sensors to measure the displacement. It does so by the laser beam focussing through the emitting lens onto an object. During this, some of the light from the laser reflected from the object produces light onto the position sensor. When the object moves, the sensor does too. 

What are the benefits of displacement sensors?

Displacement sensors offer a host of benefits that make them one of the most popular choices. Robust in nature can operate in harsh environments such as temperatures up to 175°C in corrosive media such as saline, oil, and brake fluid. The contact-free frictionless design ensures a longer life for the sensor and allows it to operate over millions of cycles without wear or degradation in signal quality. 

The use of an optical beam for detection gives a short response time. The sensors respond so quickly they are easily used on a high-speed production line. The advanced system and electronic circuit technology also allow for high accuracy; the sensors are ideal for precise micro-position movements.

What applications use displacement sensors?

It’s imperative to match a sensor's performance precisely to the demands of an application and its environment. Some applications call for high accuracy quickly, whereas some may need to operate in a corrosive fluid at extreme temperatures. Many industries favor displacement sensors because of their ability to adapt to demanding applications such as:

  • Aerospace

  • Steel production

  • Pharmaceuticals

  • Mining

  • Medical

  • Chemical processing

  • Power generation

  • Water treatment

  • Oil and gas

  • Civil engineering
