Sick VS/VE18-4N3640 Through-beam Photoelectric Sensor NPN

SKU CH-9C97-EMW8B

Through-beam photoelectric sensor detects objects up to 20 m with infrared LED and NPN output

  • Reliable detection up to 20 m range with through-beam infrared technology
  • Compact M18 cylindrical housing fits tight spaces at 78 mm length
  • NPN output with selectable light/dark switching via control cable
  • IP67 enclosure withstands harsh environments from –25 °C to +70 °C
  • Fast 250 Hz switching frequency and 2 ms response for precise sensing

Industrial Through-beam Sensor

The Sick VS/VE18-4N3640 is a cylindrical through-beam photoelectric sensor designed for industrial detection tasks. It uses an infrared LED to sense objects across distances up to 20 metres. The M18 threaded housing measures 78 mm in length and carries an IP67 enclosure rating. An M12 4-pin male connector provides the electrical interface.

Suited For Simple Presence Detection

This unit suits applications needing reliable light/dark switching with a selectable L/D control cable. The NPN output handles up to 100 mA at a 250 Hz switching frequency. Buyers requiring analogue measurement, background suppression or a PNP output type should look at alternative sensor designs. The fixed sensing configuration offers no sensitivity adjustment.

Connector And Wiring Simplify Installation

The supplied M12 4-pin connector standardises wiring in 10–30 V DC control cabinets. Circuit protection A, B, C and D guards against common electrical faults. A test input allows the sender to be disabled by pulling TE to 0 V for diagnostics. No separate mounting brackets or configuration software are included in the package.

Questions about this item

What power supply voltage range does the VS/VE18-4N3640 sensor require to operate?

The sensor operates on a 10 V DC to 30 V DC supply voltage with a maximum ripple of 10 %.

Can the VS/VE18-4N3640 be used with an existing M12 4-pin cable from an older sensor?

Yes, the sensor uses a male M12 4-pin connector, so it is compatible with standard M12 4-pin cables.

How can I verify the VS/VE18-4N3640 is detecting objects correctly after installation?

With a 250 Hz switching frequency and 2 ms response time, the NPN output will toggle reliably when the infrared beam is interrupted within the 14 m sensing range.
