Sensor type and supply voltage
The Sick VTE18-4P2640 is a photoelectric proximity sensor with an energetic detection principle. It operates on a 10 V DC to 30 V DC supply and provides a PNP switching output. The cylindrical M18 x 1 housing measures 78 mm in length and carries an IP67 enclosure rating.
Connection and output behaviour
A male M12 4-pin connector handles power and signal. Light or dark switching is selectable via the L/D control cable. The sensor delivers a maximum output current of 100 mA with a response time of 2 ms and a switching frequency of 250 Hz.
Sensing range and mounting check
The infrared LED produces a sensing range of 3 mm to 170 mm with a 10 mm light spot at 200 mm. Verify that the M18 thread matches your mounting point and that the axial optical axis aligns with the target. Ensure the 10 V DC to 30 V DC supply and PNP input are compatible with your control system.

Questions about this item
Does the M12 connector or the PBT/PC housing need periodic replacement?
The sensor has no moving parts; the M12 4-pin connector and PBT/PC housing are rated IP67 and designed for the life of the device.
What limits continuous operation — the 250 Hz switching frequency or the 2 ms response time?
The 2 ms response time sets the minimum pulse width, so the 250 Hz switching frequency is the practical ceiling for sustained cycling.
How much heat does the sensor produce when powered at 30 V DC all day?
At 30 V DC the sensor draws 30 mA, and the cylindrical PBT/PC body dissipates that power without a heatsink.
