Industrial Photoelectric Sensor
The Sick VTF18-4N5140 is a cylindrical photoelectric proximity sensor designed for industrial automation and machine-monitoring tasks. It delivers an NPN switching output with selectable light-or-dark operation for flexible integration into control systems.
Check Supply Voltage And Wiring
Verify that your control circuit provides 10 V DC to 30 V DC with ripple below ten percent. Ensure the cable harness uses a male M12 four-pin connector and that the NPN output matches the input logic of your PLC or relay module.
Brass Housing And IP67 Sealing
The nickel-plated brass barrel with plastic PMMA optics withstands ambient temperatures from minus twenty-five to plus seventy degrees Celsius. IP67 enclosure rating protects against dust ingress and temporary immersion, while the straight cylindrical profile simplifies bracket mounting in tight machine frames.

Questions about this item
Does the VTF18-4N5140 ship with a mounting bracket or an M12 cable, or must they be ordered separately?
The sensor is supplied as the unit only; a compatible M12 4-pin cable and any mounting hardware are sold separately.
Should I choose the 45 mm or 50 mm sensing range for reliable detection?
The rated sensing range is 0 mm to 45 mm; the 50 mm figure is the absolute maximum under ideal conditions, so design for 45 mm.
How does the 2 ms response time affect detection on a fast conveyor?
At 2 ms the sensor can reliably detect objects moving at typical packaging speeds; the output switches within two milliseconds of the target entering the 45 mm range.
