The ORA1L03-A0 is an infrared range-finding sensor manufactured by KODENSHI. It operates on the triangulation principle, combining an infrared LED emitter with a position-sensitive detector (PSD) to produce an analog voltage output proportional to target distance. With a detection range of 10cm to 150cm, the device targets object presence and proximity measurement in industrial automation, self-service terminals, and commercial equipment. Each unit is supplied in ESD-protective packaging, and batch traceability is available for volume procurement.
The ORA1L03-A0 emits a modulated infrared beam toward the target. The reflected light strikes the PSD at an angle determined by the distance to the object. Closer targets produce a larger incident angle, while farther targets produce a smaller angle. The PSD converts this positional change into a continuous analog voltage signal, enabling distance measurement without contact.
The sensor module incorporates an LED driver, PSD signal conditioning circuitry, and an operational amplifier on board. This integration reduces the number of external components required on the application PCB and simplifies downstream signal acquisition. The output is an analog voltage that varies linearly with detected distance, readable directly by an ADC input on a microcontroller.
The housing features two mounting holes for screw fixation, allowing secure installation on equipment chassis. The dual-hole design provides mechanical stability during assembly and reduces positional drift under vibration conditions commonly encountered in industrial environments.

The ORA1L03-A0 detects workpiece presence and measures position on conveyor systems and assembly fixtures. Its 10cm to 150cm range covers typical part-detection distances in automated handling equipment, and the analog output enables distance-based sorting or positioning logic.
In ATM equipment and vending machines, the sensor monitors product dispensing status and detects user approach. The non-contact measurement method avoids mechanical wear associated with limit switches, supporting continuous operation in high-traffic commercial environments.
The sensor supports proximity-triggered functions in interactive kiosks, digital signage, and shower toilet seats. The analog output allows designers to implement distance-dependent response behavior, such as gradual brightness adjustment or staged activation of display content.
The ORA1L03-A0 is supplied in factory-sealed ESD packaging to prevent electrostatic damage during storage and handling. For volume orders, full batch traceability is provided, including manufacturing lot identification. Commercial buyers may request sample quantities for evaluation before committing to production-scale procurement. Lead times and minimum order quantities are available upon direct inquiry.
The ORA1L03-A0 detects objects within a distance range of 10cm to 150cm. The output voltage changes proportionally across this range, allowing both presence detection and approximate distance measurement.
The sensor provides an analog voltage output that varies linearly with target distance. This signal can be read directly by an analog-to-digital converter input on a microcontroller without additional signal conditioning.
The ORA1L03-A0 is manufactured by KODENSHI, a Japanese manufacturer specializing in optical sensors and optoelectronic components.
The sensor operates from a 5V DC supply and draws approximately 25mA of current during normal operation.
The sensor is specified for an operating temperature range of -10°C to +60°C and does not carry an IP-rated enclosure. It is intended for indoor installation in controlled environments such as factory floors, self-service kiosks, and commercial equipment.
