Button photocell type have different Special function and parameter. below list this variant series.
Button type photocell, some of these example like 103X, 401X and JL-412C, JL-412CR.
well known feature Here these light controller, Chilighting also will help you to stronger self-imprint, and divide some classification.
* CDS and phototransistor, photodiode, IR-Filtered Phototransistor Sensor
*Only it suit for harsh conditions about desert, and coast, and salt fog. here recommend 103AG(G-16 AWG, 150ºC rated,1500-2000W), 103CC(ingress rating), 403c[M](Fail-off , surge protection) , 423C[M](optional failure mode, zero-crossing), and if you hard find min-cost and mini hols size design photocell switch on all the network shopping, also leave you a type JL-412C or JL-412CR, hole diameter 10 10mm approximately.
