INNOVATION IN MOTION

The SLS and MLS series of linear position sensors are designed to providemaximum performance benefits within an extremely compact size. Using the proven benefits of Hybrid Track Technology and including a number of innovative design features, these position sensors are ideally suited to applications where high performance and reliability matched by competitive pricing and rapid despatch are of 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. See page 18 for hybrid track operating principle.

Choice of mounting

A wide choice of mounting options areavailable and include self-aligning bearings,body clamp kits and flange mounting kits.Spring loaded shaft operation is offered onmodels SLS130 and SLS220.

EMC Directive 2004/108/EC The products detailed in this document have been tested to the requirements of EN61000-6-3 (Emissions) and EN61000-6-2 (Immunity). Quality Assurance Penny+Giles are accredited to BS EN ISO9001:2000Quality is at the heart of all our systems ensuring thereliability of our products from initial design to final despatch.

Environmental protection

Certificate No. LRQ0924881 ATEX94/9/EC (100a) and 1999/92/EC (137) Directives In addition to the IP66 protection that can be selected whenordering, an additional protective sleeve can be specified toprotect the operating shaft and enhance the performance ofthe SLS130, MLS130, SLS190 and SLS320 models, makingthem especially suited to particularly harsh applications in motorracing, agricultural, material handling, construction, steel manufacturing and structural monitoring applications.
Penny+Giles SLSand MLS products are potentiometers and as such are classed as ‘simple apparatus’ according to the definition in paragraph 3.21 (a) of BS EN60079- 14:1997. ‘Simple apparatus’ is not certified, but may be used as part of an intrinsically safe circuit providing it is used with a suitable interface of associated apparatus (e.g. a safety barrier). A full declaration of compliance can be supplied on request.
