ISTS2001, ISTS2002, ISTS2003 ISO - LOGIC BUFFER SCHMITT TRIGGER INTERRUPTER SWITCH Dimensions in mm ISTS2001 ISTS2003 DESCRIPTION The ISTS200_ series of transmissive photointerrupters are single channel switches consisting of a Gallium Arsenide infrared emitting diode coupled to a high speed integrated circuit detector. The output incorporates a Schmitt trigger which provides hysteresis for noise immunity and pulse shaping. The gap in the plastic housing provides a means of interrupting the signal with an opaque material, switching the output from an 'OFF' into an 'ON' state. 25.7 24.1 1 19.05 pin 3 VCC pin 4 VO 5 2 1 E 2 12.7 3.0 4 3 9.0 8.0 6.6 pin 5 GND 3.3 3.0 2.8 11.1 10.5 FEATURES l l l l l l OPTICAL CENTRE LINE 0.45 0.40 Output high under incident light Built in Schmitt trigger circuit Pull up resistor between VCC and output High sensitivity 3mm gap between LED and detector 0.25mm aperture over detector :ISTS2002, ISTS2003 7.62 2.54 ISTS2002 APPLICATIONS l Floppy disk drives, Copiers, Printers, Facsimilies, VCR's, Cassette tape Recorders, Automatic vending machines 1 25.7 24.1 19.05 pin 3 VCC pin 4 VO 5 2 1 E 2 Voltage Regulator 3 VCC 2 12.7 9.0 8.0 3.0 4 3 6.6 pin 5 GND 3.3 3.0 2.8 11.1 10.5 10kΩ 4 Out 5 GND 1 OPTICAL CENTRE LINE 0.45 0.40 7.62 2.54 Amp ISOCOM COMPONENTS LTD Unit 25B, Park View Road West, Park View Industrial Estate, Brenda Road Hartlepool, Cleveland, TS25 1YD Tel: (01429) 863609 Fax :(01429) 863581 12/1/01 ISOCOM INC 1024 S.
