Industrial Retro-reflective Sensor
The Sick WL12-2P430 is a photoelectric retro-reflective sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply with a PNP switching output suitable for automation logic. The visible red LED light source provides a maximum sensing range of 7 m and a defined sensing range up to 5 m. Adjustment is handled via a potentiometer for light or dark switching modes.
Metal Housing With M12 Connector
A rectangular zinc diecast housing measuring 15 mm x 49 mm x 41.5 mm protects the internal electronics to an IP67 enclosure rating. The optics use PMMA plastic while the 4-pin M12 male connector ensures a secure, vibration-resistant link. This construction supports an ambient operating temperature span of –40 °C to +60 °C and a storage range of –40 °C to +75 °C for harsh environments.
Check Voltage And Mounting Space
Verify that your control system supplies between 10 V DC and 30 V DC and can accept a PNP output with a 330 µs response time. Confirm the 15 mm by 49 mm footprint fits the intended bracket and that an M12 4-pin cable is available for wiring. The sensor carries UL file numbers NRKH.E181493 and NRKH7.E181493 for compliance reference.
