Gap pot­ting
The joints or edges between two vis­i­ble parts are par­tic­u­larly sus­cep­ti­ble to the ingress of dirt, dust and exter­nal media. By pot­ting these joint edges flush with the sur­face, the ingress of for­eign bod­ies and sub­stances can be effec­tively pre­vented. This not only ensures a clean and durable con­nec­tion, but also enables a higher IP pro­tec­tion class to be achieved, which sig­nif­i­cantly increases resis­tance to envi­ron­men­tal influ­ences.
Anti-​splinter film
The anti-​splinter film pro­vides effec­tive pro­tec­tion for glass front pan­els by pre­vent­ing the glass from break­ing and retain­ing dan­ger­ous splin­ters. This film not only increases safety, but can also sig­nif­i­cantly improve the shat­ter resis­tance of glass sur­faces. In addi­tion, it helps to reduce UV rays, which pro­tects the inte­rior from dis­col­oration.
Glass
Glass fronts on HMIs offer a mod­ern and user-​friendly sur­face that is both aes­thet­i­cally pleas­ing and func­tional. They pro­vide a clear view of dis­plays while pro­tect­ing them from dust and dirt. They are also easy to clean and con­tribute to the longevity of the device.

OCA Bond­ing (Opti­cally Clear Adhe­sive Bond­ing) is a tech­nique that enables touch sen­sors and glass or film sur­faces to be seam­lessly bonded together, result­ing in opti­mum vis­i­bil­ity. This method reduces glare and improves colour inten­sity by min­i­miz­ing the dis­tance between the sen­sor and the cover. OCA bond­ing also pro­vides effec­tive pro­tec­tion against bumps and scratches, which increases the dura­bil­ity of the devices.

They are avail­able in var­i­ous mate­ri­als, such as metal or plas­tic, and can be indi­vid­u­ally designed to meet the spe­cific require­ments of a prod­uct. Enclo­sures also con­tribute to heat dis­si­pa­tion and elec­tro­mag­netic shield­ing, which increases the per­for­mance and reli­a­bil­ity of the devices.
Car­rier plates
Car­rier plates are impor­tant ele­ments in elec­tron­ics that serve as a sta­ble basis for the assem­bly of parts and com­po­nents.

Resis­tive sin­gle touch­screens are a proven tech­nol­ogy that impresses with its robust­ness and flex­i­bil­ity. These touch­screens, also known as RTP (resis­tive touch pan­els), work on the basis of phys­i­cal con­tact between two con­duc­tive lay­ers that are pressed together when touched. This means they can be oper­ated with dif­fer­ent input devices such as fin­gers, pens or even gloves, which makes them par­tic­u­larly versatile.

Indus­trial applications

In con­trol tech­nol­ogy and automa­tion, resis­tive touch­screens offer a reli­able input option, even when used under dif­fi­cult conditions.

Med­ical devices

Due to their robust­ness and oper­abil­ity with gloves, they are par­tic­u­larly suit­able for use in med­ical devices, e.g. patient mon­i­tors or infu­sion pumps.

Resistive touch

Sur­face materials

The sur­face of resis­tive touch­screens often con­sists of flex­i­ble poly­ester on top of a sta­ble glass layer. This com­bi­na­tion ensures a durable and resis­tant sur­face that works reli­ably even in harsh or ster­ile envi­ron­ments. The poly­ester is easy to clean and resists scratch­ing, mak­ing it ideal for indus­trial and med­ical applications. 

Sen­sor technology

Func­tion­al­ity of PCAP multi-​touch sensors

Capac­i­tive technology

PCAP touch­screens use a thin layer of con­duc­tive mate­r­ial such as indium tin oxide (ITO). This layer forms an elec­tric field that changes when touched. This change is rec­og­nized and inter­preted by a touch controller.

Sen­sor­grid

The capac­i­tive sen­sor grid con­sists of a matrix of elec­trodes arranged in a grid struc­ture. Each elec­trode gen­er­ates an elec­tric field that changes when touched. The exact posi­tion and num­ber of con­tact points are deter­mined by ana­lyz­ing the capac­i­tance changes in this matrix. 

Sig­nal processing

The sig­nals from the elec­trodes are for­warded to a touch con­troller, which processes the data and con­verts it into coor­di­nates that are inter­preted by the device’s oper­at­ing sys­tem and software.

Touch sen­sors for sin­gle touch

The touch sen­sors in resis­tive single-​touch dis­plays are at the heart of this tech­nol­ogy. They con­sist of two trans­par­ent, con­duc­tive lay­ers that are sep­a­rated by small spac­ers. When touched, the upper layer is pressed onto the lower layer, which gen­er­ates a volt­age at the point of con­tact. This change is detected by the elec­tron­ics and rec­og­nized as a pre­cise con­tact point. This sim­ple but effec­tive mode of oper­a­tion makes resis­tive touch sen­sors extremely reli­able and ver­sa­tile, even in dif­fi­cult environments.

This solu­tion offers excel­lent dura­bil­ity and is par­tic­u­larly suit­able for indus­trial appli­ca­tions where reli­a­bil­ity and longevity are crucial.

Integrated single-touch sensor

With resis­tive inte­grated con­trollers, the con­trol elec­tron­ics are seam­lessly inte­grated into the over­all sys­tem, pro­vid­ing a com­pact and effi­cient solu­tion for touch­screen appli­ca­tions. This tech­nol­ogy enables accu­rate detec­tion of pres­sure points and reli­able oper­a­tion, even when wear­ing gloves or in envi­ron­ments where pre­ci­sion and dura­bil­ity are paramount. 

This inte­grated solu­tion is ideal for appli­ca­tions where robust, durable and cost-​effective con­trol is required, espe­cially in indus­trial and harsh work­ing environments.
