Sick VTE18-3N8112 Photoelectric Proximity Sensor NPN 10-30V DC 700mm IP67

Sick VTE18-3N8112 photoelectric proximity sensor

This Sick VTE18-3N8112 photoelectric proximity sensor detects objects using infrared LED light within a 10 mm to 700 mm sensing range. It supplies an NPN dark-switching output for automation and control circuits. The cylindrical brass housing measures 63.6 mm and carries an IP67 enclosure rating. It operates on a 10 V DC to 30 V DC supply with a 2 m PVC cable connection.

Thermals noise and power draw in normal use

The sensor consumes a maximum of 30 mA from the 10 V DC to 30 V DC supply with a 10 % ripple tolerance. A 2 ms response time supports fast switching cycles in typical industrial environments. The IP67-rated metal and plastic housing withstands ambient temperatures from –25 °C to +70 °C without active cooling. No acoustic noise is generated by the solid-state optoelectronic design.

Upgrades from basic limit switches

This unit replaces mechanical limit switches that wear out or fail in dirty or vibrating conditions. The non-contact infrared detection avoids physical actuation force and bounce. The potentiometer adjustment allows precise range setting up to 700 mm for varied target positions. Buyers who need longer range than 800 mm or a different output logic should consider other sensor types.
