Human Detection (Proximity) Sensor Switch

This sensor, mounted in the front, detects the presence of the operator as soon as he or she approaches
within 1.8 meters of the front of the machine.
• The sensor uses infrared so the maximum distance at which the operator's presence can be
detected may vary with ambient temperature.
• The standard is for the sensor to detect the operator at 1.8 meters away from the front of the
machine at ambient 28C (82F). However, this can vary with changes in ambient temperature.
• At lower ambient temperature, this distance may increase and the operator can be detected farther
away. At higher ambient temperature, the distance may decrease and the operator will have to be
closer to the front of the machine for the sensor to detect.
• The sensor monitors the space from the floor to the approximate height of the operator's knees. The
sensitivity of the sensor detection can also be affected by the operator's clothing.
