Optoelectronics Infrared Light Barriers Receivers and Emitters for Light Barriers If you want to create a security perimeter, determine if a vending item dropped, start a compacting cycle when trash reaches a certain level, stop a conveyor belt when product reaches a certain point, and you want to do it inexpensively and reliably, then you have come to the right place. Using Vishay’s infrared emitters to emit the light and fixed gain IR receivers to receive the light, a light barrier system can be added to any application. EMITTERS • • • • Narrow and wide angles of intensity Surface-mount or through-hole packages Fast rise and fall times Broad selection of intensities RECEIVERS • Fixed gain so sensitivity is unaffected and repeatable • High sensitivity with range up to 40 m • Demodulated output can be directly connected to a µC APPLICATIONS • • • • Garage door safety switch Elevator door safety switch Revolving door safety switch Conveyor systems • • • • Automatic door activation Moving sidewalk activation Escalator activation Industrial perimeter guards • Burglar alarm • Vending machines • Automatic trash compactors RESOURCES • Datasheets: http://www.vishay.com/ir-receiver-modules/presence-sensor/ • Video: http://www.vishay.com/videos/optoelectronics/safety-light-barriers-and-your-garage-door • Technical questions: [email protected], [email protected] One of the World’s Largest Manufacturers of Discrete Semiconductors and Passive Components PRODUCT SHEET 1/2 VMN-PT0402-1404 THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.

Optoelectronics Infrared Light Barriers Vishay’s TSSP4038, TSSP58038, TSSP6038, TSSP77038, and TSSP57038 feature a fixed gain. This means that the detection threshold and resulting detection distance is fixed. Once such optical parameters as the intensity of the emitter, the aperture in front of the receiver, and the alignment of emitter and detector are determined, the sensor will have stable, repeatable performance under moderate lighting conditions. In highbrightness conditions an aperture should be used to reduce the sensitivity of the IR detector. The output of the sensor is the demodulated signal of the 940 nm emitter transmitting modulated bursts at 38 kHz.
