SEALED ROTARY SENSORS

Hybrid track

Penny+Giles proven long life hybrid potentiometer track
technology (conductive plastic on wire), provides high
stability under extremes of temperature and humidity,
with virtually infinite resolution and a track life in excess
of 50 million operations. With minimal hysteresis and
electrical noise and a self-compensating effect for track
wear, this technology allows designers to achieve
improved control system accuracy and long-term
integrity without increasing system costs.

ATEX 94/9/EC (100a) and
ATEX 1999/92/EC (137) Directives

Penny+Giles SRS280 and SRS880 products are potentiometers and as such
are classed as ‘simple apparatus’ according to the definition in paragraph

3.21 (a) of BS EN 60079-14:1997.
‘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.

Rugged design - superior protection

The rugged, 88mm diameter housing in a choice of aluminium or stainless steel, includes a stainless steel operating shaft
supported by a heavy duty, twin ball-race bearing system for maximum strength. Environmental protection is achieved by
a unique double sealing system that allows the sensor to operate fully submersed to 2m.

Shaft attachment

The sensor shaft has the option of

two attachment formats that are

interchangeable with existing

installations. The sprung shaft style

is a one-piece design that eliminates

failures caused by two-piece designs.

The shaft can be sealed to meet IP50 or

IP68 protection.

Crush proof inserts

The sensor housing is a high

strength glass-filled engineering

polymer that has the added feature

of stainless steel inserts around

the mounting screw area so

preventing damage to the flange

by over-tightening. This permits

the sensor to be re-used after

installation and allows minute

adjustments to be made.

Cable outlet

The sensor rear housing has an integrally moulded cable fully sealed to IP68, effectively

eliminating the need to over-fit a moulded boot to improve sealing, thus saving the user time

and cost. To facilitate the addition of supplementary heatshrink sleeving over the cable, a

small lip on the moulding assists attachment at the sensor housing. Cable lengths of 0.5m

and 2m can be specified.

Choice of mounting

The sensor can be mounted by three M6

clearance holes through the body, or

alternatively by three M6 threaded attachment

holes in the front face. The sensor shaft has a

flat on the diameter that would allow it to be

secured by a locking screw, or an optional lever

kit can be used to attach to the moving surface via

a selection of M8 threaded holes.

SRS880 submersible rotary sensor

The SRS880 submersible rotary sensor has been specially developed to meet the harsh operating environments
in heavy duty industrial position sensing applications, including construction, agricultural and military vehicles,
steelworks and power generating plants. The sensor is sealed to meet IP68M protection.

SRS280sealed rotary sensor

The SRS 280 sealed rotary sensor has been specially developed to meet the harsh requirements of today’s
automotive, motorsport and industrial position sensing applications. Interchangeable with the popular 38mm
fixing centres format, several innovative features are included to increase reliability and performance over
similar devices already in service.
