Sick VTE18-3E8840 photoelectric proximity sensor
The Sick VTE18-3E8840 is a cylindrical photoelectric proximity sensor with an angled light emission design. It operates on a 10 V DC to 30 V DC supply voltage with a ripple of 10 percent and a power consumption of 30 mA. The sensor features an NPN switching output configured for light switching mode and a response time of 2 ms. It connects via a male M12 4-pin connector and is built with a plastic housing and PMMA optics material.
Sensing range up to 800 mm
The sensor provides a maximum sensing range of 10 mm to 800 mm and a defined sensing range of 10 mm to 700 mm using infrared light from an LED source with a 2.8° angle of dispersion. Distance adjustment is managed through a built-in potentiometer allowing precise configuration for the application. The enclosure carries an IP67 rating ensuring protection against dust and temporary immersion in water.
Suited for industrial automation needing NPN output
This sensor suits automation engineers and maintenance technicians requiring a compact cylindrical sensor with NPN light switching output for presence detection tasks. The 10 V to 30 V DC supply range fits standard industrial control voltage levels. Buyers who need a PNP switching output or a different connection type such as a cable gland should look at alternative models. The operating temperature range of –25 °C to +70 °C covers most indoor and sheltered outdoor environments.

Questions about this item
How far can the VTE18-3E8840 reliably detect an object once it is mounted on a machine?
The sensor offers a sensing range of 10 mm to 700 mm, with a maximum reach of 800 mm under optimal conditions.
What does the NPN switching output and M12 connector mean for wiring into a control system?
The NPN output sinks current to ground when triggered, and the 4-pin M12 male connector provides a standard industrial interface for quick, secure connection to a PLC or I/O block.
What clearance and mounting style does the cylindrical angled housing need?
The 75 mm cylindrical angled body requires a matching M18 mounting hole or bracket, and the angled light emission means the sensing face must point toward the target area with a clear line of sight.
