- 10–30 V DC supply with 250 Hz switching frequency
- IP67-rated PBT/PC housing for harsh environments
- M12 4-pin connector for quick installation
Cylindrical M18 photoelectric sensor
The Sick VTE18-4N8740 is a new cylindrical photoelectric proximity sensor that uses an energetic detection principle. Its M18 × 1 thread and 78 mm housing length suit standard mounting points in industrial equipment. An axial infrared LED emits a 2.8° beam that produces a 40 mm spot at 800 mm. The NPN output supports selectable light or dark switching via the L/D control cable.
Wiring and mounting requirements
A 10–30 V DC supply with ripple below 10 % powers the unit, drawing 30 mA. The 4-pin M12 male connector carries the NPN switching signal rated at 100 mA and 250 Hz. IP67 enclosure rating and a –25 °C to +70 °C operating range allow installation in wet or temperature-variable zones. Plastic PBT/PC housing and PMMA optics resist typical industrial contaminants.
Replaces older proximity switches
The sensor upgrades mechanical limit switches or earlier photoelectric units that lack adjustable range or selectable switching mode. The 270° potentiometer lets you set the sensing window between 10 mm and 700 mm without changing hardware. The jump is worthwhile when an application needs non-contact detection, faster 2 ms response, or the durability of an IP67-rated plastic body.

Questions about this item
What is the maximum sensing distance the VTE18-4N8740 can reliably detect at?
The maximum sensing range is 800 mm, with an assured operating range of 10 mm to 700 mm using the potentiometer adjustment.
How much heat or power does the sensor draw when running continuously on a 24 V supply?
Power consumption is 30 mA with a supply voltage of 10 V DC to 30 V DC and ripple below 10 %.
Which mating cable or connector must I already have to wire the M12 4-pin plug?
You need a 4-pin M12 female connector cable to match the male connector on the sensor housing.
