Key Features
Bipolar NPN + PNP Output
The sensor provides a bipolar output configuration, combining NPN and PNP open collector outputs in one unit.
M18 Threaded Mount with M12 Connector
The sensor is housed in an M18 threaded mount and terminates in a 4-pin M12 connector for installation flexibility.
Selectable Response Time
Response time can be set to 1.5 ms, 10 ms, or 50 ms to suit different detection speed requirements.
IP68 / IP69K Enclosure Rating
The sensor carries IP68 and IP69K enclosure ratings, along with NEMA 4X, for protection in washdown and demanding environments.
SUS316L Stainless Steel Case
The case is constructed from SUS316L stainless steel, with a PMMA lens cover featuring a scratch-resistant coating.
Applications
- Presence and position detection at distances up to 240 mm
- Industrial automation applications requiring a distance-based laser sensor
- Detection tasks in food and beverage processing environments
- Washdown areas where IP69K protection is required
- Small-part detection using the approx. 2.4 × 1.2 mm spot at 240 mm
- Material handling and packaging equipment
- Machine tool and assembly line sensing
