Industrial photoelectric sensor with 800 mm range
The SICK VTE18-4N8340 is a cylindrical proximity sensor that detects objects using an infrared LED beam. It operates on 10 V DC to 30 V DC and provides an NPN switching output selectable between light and dark modes via an external control cable. The brass nickel-plated metal housing meets IP67 enclosure rating for harsh environments.
Sustained detection stability across temperature
The sensor maintains its specified sensing range from 10 mm to 700 mm throughout the full ambient operating window of –25 °C to +70 °C. A 2 ms response time and 2.8° angle of dispersion give repeatable switching behaviour during continuous production-line cycles without drift or missed counts.
Low heat and quiet solid-state operation
Power consumption is limited to 30 mA at the supply rails, so self-heating stays negligible inside sealed control cabinets. No moving parts or fan means silent running, and the IP67-rated brass and PMMA construction resists coolant splash and vibration without derating.

Questions about this item
Does the VTE18-4N8340 generate noticeable heat when running continuously on a 24 V DC supply?
The sensor draws 30 mA at 10–30 V DC, so heat output is minimal during all-day operation.
What power supply and cable do I need before the VTE18-4N8340 will operate?
Provide 10–30 V DC with ≤10 % ripple and an M12 4-pin male connector to match the sensor's connection.
Will the VTE18-4N8340 fit the same 18 mm mounting holes as older cylindrical sensors?
The housing is cylindrical and angled with a 75 mm dimension; verify the exact mounting pattern against your existing brackets.
