is a specialist manufacturer of capacitive switches & sensors.
capacitives produce an electric field with which they detect
electrically conducting or non-conducting materials, solids particles or
liquids, without making contact. Target detection is not affected by
colour. Almost all Proxistor capacitives feature adjustable sensitivity
allowing them to be set-up to differentiate between materials or
compensate for varying mounting conditions.
We want to
solve your sensing problems and will consider "specials" if
our standard sensors do not provide a solution.
- Non invasive
contents detection through non metallic containers.
detection of solids, granules, powders or liquids
- e.g. for
filling applications, hopper loaders, silos, tubes, pipes,
confectionery, foodstuffs, or inks.
granule level detection for loading systems
here for examples of detection of granules, through non
metallic containers, in filling, hoppers & tubes.

offers a complete range of inductive proximity switches.
Inductive Proxistors detect the presence of ferrous or non-ferrous
metals without making contact and offer metal sensing unaffected by
dirt, oil humidity & dust. This makes them particularly suitable for
use in both the machine tool and general manufacturing environments
where they are present in great volume and variety.
Building a new machine?
We can help,
talk to us as early as possible.
We can help
reduce machine downtime.
Many inductive proximity switches comply with the same IEC
to reduce downtime:
- In practice
they can often be interchangeable, especially in an emergency. We
can probably supply replacements for your machinery from stock.
For example we list twenty one (21) varieties of M12 pnp
normally open inductives. We cannot claim all will be in stock when
you telephone! but we will get your machinery running with one or
another of them.
- We may have a
stocking reseller near you. If not, we ship daily with UPS or TNT or
Federal Express or Securicor etc. We can get parts to you quickly
wherever you are.
You know one switch or another on your machines will fail at some
point in the future. You cannot hold replacements for all of them.

offers photoelectric switches using visible and infrared light sources
in diffuse, retro-reflective and through-beam configurations.
Photoelectrics offer sensing solutions for a wide range of
Each sensing method (diffuse, retro-reflective and through-beam)
incorporate a light emitter and a receiver. In all but through beam
types, the emitter and receiver are housed in a single sensor unit.
Using diffuse reflective types, target detection is caused by light
reflection from the target itself.
For retro-reflective and through-beam types the target must cut the
light beam to activate the sensor.
Typical Applications -

adequate echo reaches the sensor.
Ultrasonic sensors produce an inaudible sound wave which must be
reflected by a target to trigger object detection.

Mounting brackets for cylindrical threaded sensors.
We offer ready made mounting brackets for cylindrical proximity
switches in a number of styles. Unless you like making brackets save
time, buy them ready-made with your sensors.
(note: smooth diameter capacitives and inductives are supplied
with mounting shell kits included, threaded cylindrical sensors are
supplied with nuts as standard but not brackets, rectangular
photoelectric sensors are supplied with mounting brackets included)

switches and sensors are produced using surface mount technology in the
case of capacitive sensors they are sealed into UL V0 housings with
flame retardant epoxy encapsulation conforming to requirements for the
type 2, double insulated, construction form.

improve sensing techniques and produce custom solutions. Very often a
variation on a standard Proxistor or AB Electronic device can provide a
solution for a difficult application.
