Sensor type and output
The Sick VTF18-4N1640 is a photoelectric proximity sensor with background blanking and a cylindrical M18 housing. It uses focused infrared LED optics and provides an NPN switching output with selectable light or dark switching via the L/D control cable. The unit operates on 10 V DC to 30 V DC supply voltage and connects through a 4-pin M12 male connector.
Suitable users and limits
This sensor suits automation tasks that require axial detection within a 3 mm to 90 mm sensing range and a 250 Hz switching frequency. Its IP67 enclosure rating and –25 °C to +70 °C operating range support harsh industrial environments. Buyers who need longer sensing distances, PNP output logic, or adjustable sensitivity should look at alternative models.
Included accessories and software
The product is supplied as the sensor unit only with no additional accessories, cables, mounting brackets or configuration software in the package. Users must source a compatible M12 cable and any required mounting hardware separately. No software installation or firmware updates are needed for basic operation.

Questions about this item
What supply voltage must my system provide for this sensor?
The sensor operates from a 10 V DC to 30 V DC supply with a maximum ripple of 10 %.
Will the M12 4-pin connector on this sensor mate with my existing M12 cables?
Yes, it uses a standard male M12 4-pin connector compatible with common M12 cables.
How can I verify the sensor is switching correctly after installation?
Monitor the NPN output; it toggles at up to 250 Hz with a 2 ms response time when the target enters the 3 mm to 90 mm sensing range.
