E2 INDUCTIVE SENSORS
When failure is not an option

Zero tolerance on failure
Small things sometimes have a big impact.
Proximity sensors may be small and relatively
inexpensive, but malfunctions can create big
problems for you and your operation –
in machine downtime, expensive delays and
lost business.
That’s why you can’t take chances even with
the small things. And neither do we! With our
E2 Inductive Proximity Sensor series, we take
a zero-tolerance approach to failure.
Which means we leave nothing to chance.
We design the sensors to withstand the toughest
conditions they’re ever likely to experience
in operation. We manufacture them using the
most tightly-controlled production processes –
with stringent checks at every stage to guarantee
unsurpassed quality and reliability. And we
subject them to the most demanding tests
available to the industry today.
Providing objective proof that the E2 series
is indeed what we claim – the natural choice
when failure is not an option.

E2FM sensorsE2FM sensors
Stainless steel for machine-tool toughness
For demanding environments in, for example, machine tool
equipment, E2FM Stainless Steel sensors are the perfect
choice. Their tough all stainless steel housing is highly
resistant to impact, abrasion and aggressive chemicals
and oils.
They also feature a sensing surface 0.8 mm thick – 4 times
thicker than that of ordinary stainless steel proximity sensors
– making them over 20 times tougher. We’ve proved this
in continuous-impact tests in which ordinary stainless steel
sensors are penetrated after just 10,000 impacts, while
the sensing surfaces of E2FM sensors are still intact even
after 250,000 impacts. The sensors also feature a special
ruggedized cable that’s resistant to welding sputter. So they
will continue operating in the toughest workshop conditions
long after other stainless steel sensors have been consigned
to the recycle bin.
E2FM sensors also require less frequent cleaning than ordinary
sensors thanks to the use of optimised low-frequency pulse-
modulation circuitry that ignores the small metal chips that
build up on the sensing surface during milling and cutting.
So your process can continue running, interrupted only
by your normal cleaning and maintenance cycles.

Anti-microbial housing
Intensive cleaning reduces the risk of food contamination
through bacteria and microbes and ensures highest hygiene.
The anti-microbial housing of the E2F-D provides added
protection against bacteria growth between cleaning cycles
using a silver ion based additive actively inhibiting and
killing bacteria.
Heat and detergent resistant
Ensuring highest hygiene in food processing applications
requires intensive cleaning with high pressure, high
temperatures and aggressive alkaline or acid based
detergents. The high grade 316L stainless steel and the
certified detergent resistance provide an easy-to-clean and
durable housing. The heat resistance up to 120°C make the
E2EH the first choice for usage in demanding environments
in meat processing, cooking or baking applications.

E2AU sensorsE2AU sensors
Keeping moving machinery on the move
E2AU sensors are based on our proven E2A proximity sensor
family, and offer the same exceptional quality and reliability for
which this family has long been renowned.
Intended specifically for demanding applications in moving
machinery such as refuse-disposal trucks, earth-moving
equipment and construction and agricultural vehicles, the
sensors meet and even exceed today’s most severe regulatory
standards for moving vehicles. These include e1 type approval
(eMark) according to the European Automotive Directive
95/54/EC and electro-magnetic noise immunity up to 100 V/m
according to ISO 11452-2.
Their exceptionally rugged construction, including a tough
cable connection, sealing against water and dust to IP69K, and
their resistance to vibration, mechanical shock and temperature
extremes, means these sensors are well able to share the tough
working life and conditions of today’s utility vehicles.

E2AX sensors
E2A3 sensorsE2A3 sensors
Triple sensing distance for enhanced reliability
Our E2A3 sensors offer sensing distances up to 3 times the
standard distance defined by CENELEC, greatly reducing the
likelihood of the sensing surface being struck and perhaps
damaged by moving machine parts. Thanks to the use of
optimised sensing circuitry and new sensor geometry, the
sensor is able to send a stop signal to the machine much
earlier than standard- or double-distance sensors without
any compromise to sensor performance.
E2AX sensors
Explosion protection in dusty environments
Intended for use in potentially explosive atmospheres
using substances from sawdust to flour, E2AX sensors meet
demanding regulatory requirements governing explosion
protection - including ATEX certification Group II category 3D
(94/9/EG Appendix VIII).
To minimise the possibility of ignition from exposed circuitry,
their robust, hermetic housings are designed to withstand
mechanical shock without fracture, and the sensors also
feature a special retaining bracket to prevent the cable being
detached during operation.
ATEX certification, which is done by an independent
notified body, relates not just to the products but also to
the production facility which must provide a regime of full
traceability in the event that a malfunction occurs leading
to an explosion.
E2AX
The Ball Drop Test is part of the
ATEX approval ensuring high
mechanical protection
of electronic parts.
