Sick VTE18-4P4640 Photoelectric proximity sensor PNP

Industrial Photoelectric Proximity Sensor

The Sick VTE18-4P4640 is a cylindrical photoelectric proximity sensor with an M18 x 1 thread and a 78 mm housing length. It operates on a 10 V DC to 30 V DC supply and uses an infrared LED light source with an axial optical axis. The sensor provides a PNP switching output with selectable light or dark switching via an L/D control cable. It connects via a 4-pin M12 male connector and weighs 100 g.

Suited for Automation and Presence Detection

This sensor suits applications requiring object detection within a 5 mm to 350 mm sensing range and a maximum range of 400 mm. The IP67 enclosure rating and an operating temperature span of –25 °C to +70 °C support use in harsh industrial environments. Buyers needing a sensor with adjustable sensitivity, background suppression, or a different output logic such as NPN should look at other models. The fixed 2 ms response time and 250 Hz switching frequency may not meet high-speed counting requirements.

Verify Mounting and Electrical Compatibility

Confirm the M18 x 1 thread matches your mounting hardware and that the 78 mm housing length fits the available space. Ensure your control system accepts a PNP output with a maximum load of 100 mA and can supply 10 V DC to 30 V DC with ripple below 10 %. The 4-pin M12 connector requires a matching cable or distribution box. Check that the plastic PBT/PC housing and PMMA optics withstand any chemicals or mechanical stress present in the installation area.
