  • Fast 250 Hz switching frequency for high-speed automation tasks
  • Wide 10 V DC to 30 V DC supply voltage fits standard control systems
  • Rugged IP67 nickel-plated brass housing withstands harsh industrial environments
  • Compact M18 cylindrical design with axial optics simplifies machine integration

Industrial proximity sensor for automation

The Sick VTE18-3F4140 is a cylindrical photoelectric proximity sensor built for industrial automation tasks. It uses an energetic detection principle with an infrared LED to sense objects without physical contact. The metal nickel-plated brass housing measures 78 mm in length with an M18 x 1 thread for standard mounting. This sensor suits engineers integrating presence detection into conveyor lines, packaging machines or robotic cells.

PNP light-switching output at 10–30 V DC

The single specification that decides fit is the PNP light-switching output driven from a 10 V DC to 30 V DC supply. The four-pin M12 male connector delivers a maximum load current of 100 mA with a 2 ms response time and 250 Hz switching frequency. Wiring must match this PNP polarity; NPN or push-pull controllers will not operate correctly with this device.

Stable detection up to 350 mm in harsh environments

Under sustained operation the sensor maintains its 5 mm to 350 mm sensing range across an ambient temperature span of –25 °C to +70 °C. The IP67-rated enclosure and PMMA optics resist oil, coolant and wash-down cycles without fogging or ingress. Power consumption stays at 30 mA with ripple below 10 %, so the output remains consistent during continuous 250 Hz cycling over long shifts.

Questions about this item

What does the 350 mm sensing range mean when the sensor is installed on a machine?

It reliably detects objects from 5 mm up to 350 mm away using its infrared LED, with a 20 mm light spot at the maximum 400 mm distance.

How does the M12 4-pin connector limit the sensor's wiring and output options?

The M12 4-pin male connector carries the 10–30 V DC supply and the PNP light-switching output rated at 100 mA, with a 2 ms response time and 250 Hz switching frequency.

What mounting clearance and panel cut-out does the M18 x 1 threaded barrel need?

The cylindrical metal housing is 78 mm long with an M18 x 1 thread and axial optical axis, requiring an 18 mm clearance hole and enough depth for the 78 mm body behind the panel.
