Remote Amplifiers for Capacitive SensorsAdvanced functionality and flexibility

Typically, standard capacitive sensors are in M12 to M30 tubular

housings, yet smaller form factors are necessary when trying to

precisely detect small parts or in space-restricted applications. To

address these needs, Balluff offers a wide variety of sensor types,

including an exclusive line of small capacitive sensors that can be

calibrated remotely using a separate amplifier.

Balluff’s capacitive sensor amplifiers provide functionality and

capabilities not offered by other industrial capacitive sensor

manufacturers. With over 30 different sensor heads, challenging

applications can be solved reliably including precision sensing, high

temperature, carbon fiber molding, and level control.

Remote Amplifiers for Capacitive SensorsAdvanced flexibility and functionality

Three amplifier models are available:

Standard

■ Provides discrete on/off control used in most general applications

■ Output is completely configurable by using the white wire -

PNP/NPN, NO/NC

■ Setup is easy with a 20-turn potentiometer

■ Multiple LED’s for sensor status and diagnostics - power on, NPN

selected, NC selected, output function, error for missing sensor

head or bad sensor cable

■ Easy connection with either a 2m cable or M12 pigtail connector

■ Easy mounting with standard DIN rail

■ Transparent cover for controls and LED’s

Advanced

Provides all the functionality of the standard version plus:

■ Current or voltage analog output in lieu of a discrete output

■ Two color 7-segment digital display for menu item and numerical

value

■ Programming buttons

■ Available operating modes:

– Standard discrete on/off control mode

– Analog output mode - No other manufacturer of standard

capacitive sensors offers this ability. Applications include dynamic

level control and part in position.

– 2 point switching mode

– Window mode

– Dynamic mode

– Special function (pump) mode

■ External triggering

■ On/Off switching delay

Provides all of the functionality of the advanced (comfort) version plus:

■ IO Link communication for parameterization, error free re-calibration,

faster troubleshooting and reduced downtime

■ SIO mode – without the IO Link master the amplifier acts like a

standard amplifier after configuration with IO-Link

■ Connection via M12 pigtail connector

Operating Modes

Standard Switching mode

Provides standard on/off control e.g. the output changes state based

on the adjustment of the sensitivity pot (one defined switch point).

The sensing range is dependent on the sensor head being used. The

output will turn off when the object is out of range.

Two-Point Switching

Separate defined switch points, Switch Point 1 for the output to switch

state and Switch Point 2 for the output to return to the normal state.

The hysteresis is limited by the switch point configuration.

Window Function

Output is actuated when the sensor is within the separate Switch

Points 1 and 2. The standard hysteresis is in effect with this switching

function.

Dynamic Operation

Output changes state only to fast movement within the sensing

range of the sensor. If an object or background does not move, the

amplifier ignores it. This mode is similar to a background suppression

photoelectric sensor.

External Triggering

Utilized to set the Set Point 1 or High Limit and Set Point 2 or the Low

Limit. The feature uses the white wire and has three states. State one

is open thus disabling the external triggering function. State 2 connects

the white wire to positive voltage enabling the ability to teach Set Point

1 or the High value. Finally, State 3 connects the white wire to negative

enabling the ability to teach Set Point 2 or the Low value.

Special (Pump) Function

Requires two amplifiers and two sensor heads. Sensor/amplifier one

controls the minimum level and sensor/amplifier two controls the

maximum level.

Output On-Delay

Delays the output up to 65 seconds (in 10msec increments) before

turning on.

Output Off-Delay

Delays the output up to 65 seconds (in 10msec increments) after

turning off.

Remote capacitive amplifiers provide flexibility and benefits not offered

with self-contained sensors. This includes precisely detecting small

parts in space limited machines or robot end of arm effectors and

allowing the remote teaching of set points and output configuration.

A standard capacitive amplifier offers basic discrete on/off control with

additional diagnostics for ease of troubleshooting and setup.

The advanced (Comfort) amplifier provides functionality previously not

available in any type of capacitive sensor. Especially interesting is the

ability to have an analog output from a standard capacitive for level

control or positioning. Other functionality includes two-point switch,

window mode, and dynamic mode.

The sensor has a programming wire

(white) that can be used to configure

the output. The cable is open in

configuration mode. This status is

displayed by the LED ERR by flashing.

After each potential transition of the

programming wire from

open to positive voltage, the switching

output configuration is indexed forward

a variant each time:

PNP, NO PNP, NC NPN,

NO NPN,

NC PNP, NO, etc.

With the advanced version the white

wire is used to dynamically make set

point changes. High and low set points

can be changed by applying positive

voltage or by grounding.

CD/DVD production: Checking stack height

During CD/DVD production, capacitive sensors monitor the stacks of

CDs and DVDs on a spindle. As soon as the maximum stack height

is reached, the sensor sends a message that allows the finished

stack to be transported further to end packaging and the next empty

spindle to be prepared. And it does this with absolute reliability,

without allowing itself to be influenced by the reflective surface.

Sensors in UsePaper and printing industry: Stack height control in sheet-feed offset printing

Integrated in printing, folding and bookbinding machines, capacitive

sensors not only check stack height, but also provide for perfect

stacking of the papers, so that there is as little waste as possible

during further processing.

Despite a dirty environment (due to paper dust and anti-set-off

spray powder), the sensor works perfectly. Laterally or from above,

it measures stack heights even in small increments, and raises and

lowers the stack as soon as it recognizes its height.

In the paper cutting machine, the capacitive sensor also measures

the width of the stack to be cut, so that the cutting pressure of the

cutting knife can be set in relation to it. In doing so, it proves to be not

only insensitive to dust, but also completely uninfluenced by different

colors of paper.

18

Capacitive Sensors for Object DetectionSensors in use

Application:

Level detection of liquid media In test-

tubes

Benefits:

Analysis devices are often very compact,

so there is little space for sensors.

Miniature capacitive sensors are suitable

for small space designs.

Application:

A capacitive level sensor detects the level

of powder through a glass storage tank

wall.

Benefits:

Powder residues causing adherence

on the inner tank wall are compensated

by the capacitive sensor. The complete

active surface of the sensor covers the

outer tank wall.

Application:

Transportation control of wafers in a

wafer etching plant

Benefits:

■ The capacitive sensors can be

completely integrated in a robot arm.

■ Enables robot application designs

to accommodate for constrictions

caused by small space available in

the wafer carrier box.

Application:

A capacitive sensor detects the fill level

of soldering paste in the cartridge of a

dispenser in a screen printing machine.

The dispenser doses the soldering

paste on to a pattern or on to a screen

for PCB printing purposes.

Benefits:

Soldering paste residues on the

inner wall of the cartridge can be

compensated by capacitive sensors.

Application:

Detecting paper stack on a paper

processing machine

■ Detection from above or side.

■ Sensor detects stack height and

generates a signal, when the max.

height is reached

Benefits:

Paper processing environment (i.e. paper

dust and spray powder) has no influence

on sensor function.
