Qt30cm Transmissive Infrared ThroughBeam Photoelectric Switch The QT30CM is a twopiece infrared photoelectric sensing system designed for reliable throughbeam detection. It consists of an infrared emitter tube and a receiver tube paired as 1 pair to form a transmissive photoelectric switch. When an object interrupts the IR beam between the emitter and receiver, the receiver generates a switch signal. This noncontact sensing helps extend the life of the system and reduces maintenance. Key benefits Noncontact object detection: detects presence or absence without physical contact, reducing wear on mechanical switches. Fast, reliable response: suitable for environments requiring quick detection and low false triggering. Simple alignment: transmitter and receiver are aligned to form a clear line of sight, delivering stable performance over the specified range. Key attributes Type: transmissive infrared throughbeam photoelectric switch Configuration: 1 pair (infrared emitter tube and infrared receiver tube) Model: QT30CM Detection distance: up to 30 cm Sensing principle: beam interruption between emitter and receiver to generate a switch signal Application: ideal for automation tasks requiring presence/absence sensing across a defined gap Compatibility and integration Designed to interface with standard control circuits and automation layouts that use photoelectric sensing Requires proper alignment of emitter and receiver tubes to ensure reliable detection Suitable for use in conveyor lines, automation cells, and machine guard applications where noncontact sensing is preferred Typical use cases Conveyor line object detection: monitor moving items and trigger sorting, accumulation, or stop gates as objects pass between the emitter and receiver Endoftravel or limit sensing: detect the position of doors, gates, or moving machine components to control motion or safety interlocks Part presence verification: confirm the presence of components at a workstation or packaging stage to advance to the next processing step Notes on installation and operation Ensure a clear line of sight between the emitter and receiver tubes for accurate detection Align the transmitter and receiver so the IR beam is unobstructed over the full 30 cm range Use in applications where noncontact, reliable detection is preferred over mechanical switches This description reflects the product's model QT30CM, its transmissive throughbeam infrared sensing principle, the 1 pair configuration, and the specified detection distance, while outlining practical benefits, attributes, compatibility considerations, and use cases.
