Funzione

I sensori di contrasto serie DK10, DK2X, DKE2X e DK3X presentano una custodia standard industriale estremamente robusta con tenuta IP67, con otto inserti rinforzati in metallo M5 per il montaggio del sensore. Le lenti sono realizzate in vetro di alta qualità. Tutti i sensori offrono diverse forme e orientamenti degli spot luminosi e presentano potenti uscite push-pull (NPN/PNP/push-pull).

La serie di sensori DK10 offre sorgenti luminose laser e LED, regolazione manuale della sensibilità e range di rilevamento elevati fino a 800 mm.

La serie di sensori di contrasto standard DK20/DK21/DKE2X offre un buon riconoscimento del contrasto e sono disponibili in custodie in acciaio inossidabile estremamente robuste (DKE).

La serie di sensori DK31/DK34/DK35 è progettata per un riconoscimento del contrasto all'avanguardia con il massimo livello di sensibilità.

Le serie DK20/DK34 offrono un teach-in statico, le serie DK21/DKE21/DK31/DK35 un teach-in dinamico.
