fea tures photologic ? output four output options mechanical switch replacement 3-pin connector (ho tien l2561-03), molex compatible connector 5102 series housing and 5103 series terminal de scrip tion the opb695 series flag switches consist of an infrared emitting diode and a monolithic integrated circuit, which incorporates a photodiode, a linear amplifier, and a schmitt trigger. a lever arm actuated flag interrupts the light beam switching the output between states that can readily drive logic gates. this switch is designed to easily snap mount into a 0.037" 0.001" (0.94 mm) thick material with a rectangular opening of 0.320" 0.003" x 0.472" (8.13 mm x 11.99 mm) minimum. insertion into the punched side of metal is recommended. customized lever arms and spring torques can be designed for specific applications. the device features ttl/lsttl compatible logic level output which can drive up to 10 ttl loads over a voltage range from 4.5 v to 16 v. ab so lute maxi mum rat ings (t a = 25 o c un less oth er wise noted) stor age tem pera ture range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 o c to +100 o c op er at ing tem pera ture range . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 o c to +100 o c in put di ode for ward dc cur rent . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50 ma peak for ward cur rent (1 m s pulse width, 300 pps) . . . . . . . . . . . . . . . . . . . . . . . . 3.0 a re verse dc volt age . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.0 v power dis si pa tion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 mw (1) out put pho tologic ? sup ply volt age, v cc . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18 v du ra tion of out put short to v cc . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.00 sec volt age at out put . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30 v low level out put cur rent (sink ing) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 ma power dis si pa tion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 240 mw (2) notes: (1) der ate line arly 1.33 mw/ o c above 25 o c.
