La famiglia di sensori della serie 28 è universale. Comprende una vasta gamma di modelli che è possibile integrare in diversi ambienti per automazioni di qualsiasi tipo. I sensori sono alloggiati in resistenti contenitori di plastica impermeabili, con numerose opzioni di serraggio e dotati di una copertura ottica resistente ai graffi. Caratteristiche quali una funzione timer, la commutazione luce/buio, il regolatore di sensibilità e LED di stato dall'elevata visibilità, semplificano l'utilizzo e snelliscono le attività di installazione, configurazione e funzionamento. Con questi sensori è possibile eseguire agevolmente qualsiasi attività associata al posizionamento, al trasporto su nastri e al monitoraggio.
