  • Functions from –25 °C to +70 °C ambient temperature

Industrial Proximity Sensor

The SICK VTF18-3P5840 is a photoelectric proximity sensor built for industrial automation and machine safety. It detects objects at distances up to 45 mm using an infrared LED and a potentiometer for range adjustment. The PNP dark-switching output suits PLC inputs in packaging, conveying and assembly equipment. Its cylindrical angled housing fits tight mounting spaces.

Sustained Load Behaviour

The sensor draws a constant 30 mA across the 10 V DC to 30 V DC supply range with ripple below ten percent. Response time remains at 2 ms during continuous operation, so repeated actuations do not slow the switching signal. The potentiometer setting holds without drift, maintaining the configured sensing distance over long shifts. Dark-switching logic keeps the output stable when the beam is uninterrupted.

Thermals Noise Power

Operating temperature spans –25 °C to +70 °C with the same limits for storage, so the unit tolerates cold starts and hot ambient conditions without derating. The IP67 enclosure seals the plastic housing and PMMA optics against dust and temporary immersion, eliminating ingress-related faults. No moving parts or fan means silent operation and zero acoustic contribution to the machine environment. Power consumption stays at 30 mA under normal load.

Questions about this item

Does the sensor generate noticeable heat or draw much current when it runs continuously on a 24 V supply?

Power consumption is 30 mA at the supply voltage, and the operating temperature range is –25 °C to +70 °C, so heat output is minimal during all-day operation.

What power supply and connector must I already have to wire this PNP sensor?

You need a 10 V DC to 30 V DC source and a female M12 4-pin connector that matches the sensor’s male plug.

Will the M12 connector and 10–30 V range work with the older PLC input cards I keep in the cabinet?

The sensor uses a standard M12 4-pin connector and accepts 10 V DC to 30 V DC, which matches most legacy PLC input modules that support PNP dark-switching signals.
