Industrial proximity sensing
The Sick VTE18-4P4312 is a cylindrical photoelectric proximity sensor with a PNP switching output designed for industrial automation tasks. It detects objects using an infrared LED across a sensing range of 5 mm to 350 mm, with a maximum range reaching 400 mm. The metal housing carries an IP67 enclosure rating for harsh environments.
Straightforward wiring and alignment
Connection is made via a 2 m PVC cable with a 0.14 mm² conductor cross-section, operating on a 10 V DC to 30 V DC supply with a 10 % ripple tolerance. A potentiometer allows manual adjustment of the sensing threshold while the L/D control cable selects light or dark switching modes. The angled light emission and 2.8° dispersion angle require careful axial alignment during installation to avoid missed detections.
Consistent response under continuous duty
The sensor draws 30 mA and delivers a 2 ms response time suitable for repetitive cycling on production lines. Its brass nickel-plated metal housing and PMMA optics withstand ambient temperatures from –25 °C to +70 °C during sustained operation. The IP67 seal maintains reliability when exposed to coolant spray or dust over long shifts.

Questions about this item
How do I verify the sensor is operating correctly after wiring it to a 10 V DC to 30 V DC supply?
The PNP switching output toggles when an object enters the 5 mm to 350 mm sensing range; use the L/D control cable to select light or dark switching and confirm the LED changes state.
What comes in the box and what must I purchase separately?
The unit includes a 2 m PVC cable with 0.14 mm² conductors and a brass nickel-plated metal housing; mounting brackets and a DC power supply are not included.
Which sensing range version should I choose for detecting objects up to 350 mm away?
This model provides a 5 mm to 350 mm sensing range with a 2.8° angle of dispersion; select it when the maximum detection distance required is 350 mm.
