GU (General Use)-E Type 1-Channel (Form B) 4-pin Type FEATURES
4.78 .188 6.4 .252 3.2 .126


3. Compact 4-pin DIP size The device comes in a compact (W)6.4×(L)4.78×(H)3.2mm (W).252×(L).188×(H).126inch, 4-pin DIP size 4. Controls low-level analog signals PhotoMOS relays feature extremely low closed-circuit offset voltage to enable control of low-level analogsignals without distortion. 5. High sensitivity, low ON resistance Can control a maximum 0.13 A load current with a 5 mA input current. Low ON resistance of 18Ω (AQY410EH). Stable operation because there are no metallic contact parts. 6. Low-level off state leakage current
