Sick VTE18-3E2340 photoelectric sensor
The Sick VTE18-3E2340 is a cylindrical photoelectric proximity sensor with an NPN switching output designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 30 mA and features a potentiometer for sensitivity adjustment. The metal housing with brass nickel-plating and plastic components achieves an IP67 enclosure rating for harsh environments.
Detection range and output constraints
The sensor detects objects from 3 mm to 170 mm with a maximum sensing range of 200 mm using an infrared LED with a 2.8° dispersion angle. Light switching mode activates the NPN output when the beam is received and the response time is 2 ms. The M12 4-pin male connector provides the sole interface for power and signal connections.
Installation checks before ordering
Verify that your control system accepts an NPN light-switching signal and can accommodate the 10 V DC to 30 V DC supply voltage with a ripple below 10 %. Confirm the M12 4-pin connector matches your cabling and that the 75 mm cylindrical angled housing fits the available mounting space. Ensure the operating temperature range of –25 °C to +70 °C covers the intended application environment.

Questions about this item
Which sensing range version suits my application — the 3 mm to 200 mm maximum or the 3 mm to 170 mm standard?
The sensor detects objects from 3 mm up to 200 mm at its maximum range, while the standard sensing range is rated at 3 mm to 170 mm.
What does the 2 ms response time mean when the sensor is installed on a production line?
The output switches within 2 ms of detecting a target, allowing reliable detection of fast-moving parts on conveyors or feeders.
How does the M12 4-pin connector limit the wiring options for this NPN sensor?
The 4-pin M12 male connector carries supply voltage, ground and the NPN switching output, so it fits standard 4-wire sensor cables without extra adapters.
