Sr23-5-Ir-Ph Label Sensor Infra Red Pnp

SKU: 

953161010

Description
ico-plus ico-minus
The Datalogic SR23 is a fork-style photoelectric sensor built for automated labeling and packaging machinery where precise, high-speed label detection is essential. Using an infrared 850 nm light source modulated at 50 kHz, it reliably distinguishes individual labels from their backing, including multilayer and booklet labels, through a 5 mm slot width and 50 mm slot depth. A switching frequency of 12 kHz and a response time of 40 µs max support fast conveyor lines running at up to 20 m/min during setup. The IP65-rated zinc alloy housing withstands demanding industrial environments, while both dynamic and static acquisition modes — selectable via a single SET push-button — make commissioning straightforward. Available in PNP or NPN output versions with either a 2 m cable or an M8 4-pole connector, it fits cleanly into processing, packaging, and automatic labeler applications.

What types of labeling applications is the Datalogic SR23 Fork/Label Photoelectric Sensor designed for?
The SR23 is designed for label detection in automated labeling and packaging machinery, including multilayer and booklet label setups, as well as material handling applications where precise gap-and-label discrimination is required.
What is the slot size of the Datalogic SR23, and what are the minimum detectable label and gap dimensions?
The SR23 has a slot width of 5 mm and a slot depth of 50 mm. The minimum detectable label width and minimum space between labels are each 0.5 to 2 mm, depending on the transparency of the label support.
What output types and connection options are available on the Datalogic SR23?
The SR23 is available with either PNP or NPN output and can be ordered with a 2-meter 4-wire cable or an M8 4-pole connector, with both output and connection choices selected at the time of ordering.
What are the operating temperature range and ingress protection rating of the Datalogic SR23?
The SR23 operates from -20 to 55°C and carries an IP65 mechanical protection rating, making it suitable for demanding industrial production environments.
How is the Datalogic SR23 set up for accurate label detection, and what conveyor speed is supported during the setting procedure?
The SR23 supports both static and dynamic acquisition modes, configured via a single SET push-button or the remote input; during dynamic acquisition, labels must pass through the sensor slot at a maximum speed of 20 m/min (30 cm/s). Settings are saved to onboard EEPROM non-volatile memory.
What is the warranty period for the Datalogic SR23?
Datalogic Automation warrants the SR23 against defects for 36 months from the manufacturing date, with repair or replacement provided free of charge during that period.
