OPTOELECTRONICS Proximity Sensors Proximity Sensing from 2 mm to 2 m Many applications require a sensor that detects not only the presence of an object, but also its relative proximity. Vishay’s proximity sensors emit pulses of infrared light which reflect off an object back to the sensor. The strength of that reflected signal is used to determine the proximity of the object. A change in the reflected signal strength can be used to determine if an object is moving toward or away from the sensor.

OPTOELECTRONICS Proximity Sensors IR RECEIVERS The IR receiver-based sensors sense proximity using an onboard AGC circuit that reduces the gain in response to a reflected long burst signal from an IR emitter. The amount of time required to completely suppress the signal, and correspondingly the output pulse width, is proportional to the strength of the signal, which in turn is inversely proportional to the distance to the object. A near object reflects more light, resulting in a longer pulse width. A longer pulse width takes more time to suppress. Based on this time, the relative proximity of the object can be determined. Depending on the IR Emitter and Sensor package (see table below), ranges from 5 cm to 2 meters can be sensed. +3.3 V 500 ms VSLB3940 VSLB3940 Infrared Emitter Signal 15 Ω 120 ms high 380 ms low 38 kHz burst TSSP4P38 38 kHz SAL6200 120 ms +3.3 V TSSP4P38 Strong Reflection OUT to μC Weak Reflection * TSSP4P38 IR EMITTER OBJECT REFLECTIVITY (%) RANGE (cm) RESISTOR VALUE IRED CURRENT (mA) CURRENT CONSUMPTION (mA) RANGE RESOLUTION (%) VSMB3940 60 % 5 to 20 2.2 kΩ 5 0.67 ± 2.5 8 to 50 2.2 kΩ 5 0.67 20 to 100 390 Ω 15 0.96 40 to 200 15 Ω 50 2.81 VSLB3940 15 % ± 5.0 PROXIMITY SENSORS TSSP4P38 6.0 W TSSP58P38 5.0 W 5.6 H TSSP77P38 4.8 H TSSP6P38 3.0 W TSSP57P38 5.3 W 3.95 W 4.0 H 6.9 L 6.9 L 3.2 H 75 L 7.5 6.8 H PROXIMITY (PWM Out) 0.8 D 3.95 H REFLECTIVE RANGE (m) SUPPLY VOLTAGE (V) RESPONSE TIME (µs) CURRENT CONSUMPTION (mA) 0.2 to 2 2.5 to 5.5 300 0.7 TSSP4P38 TSSP58P38 TSSP6P38 TSSP77P38 TSSP57P38 Product Literature 5/6 VMN-PL0479-1409 THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
