TPL1241

The TPL1241 is a kind of compact photointerrupter with attched connector which uses a high-radiant power GaAs infrared LED and a Si photo IC. The TPL1241 device is a photointerrupter in highly reliable package which eliminates the need for printed circuit board and soldering. TPL1241 is optimum as a paper carrier location sensor for copiers and page printers. For the operating temperature is up to 95, the device can be used for high-temperature applications like paper-out sensors or air direction for air conditioner louvers. Open collector outputs are enabled using a phototransistor.

There are some features of TPL1241 as follows: (1)high reliability package (PWBless, Solderingless); (2)small package; (3)mountable by one touch (snap-in mounting type); (4)mountable to boards in 3 kinds of thickness (1.0 mm, 1.2 mm, 1.6 mm); (5)gap: 5 mm; (6)resolution: slit width 0.5 mm; (7)high temperature operating: Topr=95; (8)high current transfer ratio: IC/IF: 5% min; (9)digital output (open collector); (10)connected to the CT connector (2 mm pitch MT receptacle type made by AMP (Japan). Ltd); (11)material of the case: body: polycarbonate (UL94V-2, black); connector: polybutylene terephthalate (UL94V-0, white).

The last one is about the maximum ratings of TPL1241(Ta=25): (1) forward current, IF: 50 mA; (2)reverse voltage, VR: 6 V; (3)collector-emitter voltage, VCEO: 35 V; (4)emitter-collector voltage, VECO: 5 V; (5)collector power dissipation, PC: 75 mW; (6)collector current, IC: 50 mA; (7)operating temperature range, Topr: -30 to 95; (8)storage temperature range, Tstg: -40 to 100.
