- Housing: 1 3/8 12 T.P.I. Threaded
Aluminum - Sensor Power Requirement: Current Limited
12VDC from Control Unit - Unit Sensor Cable: Unshielded Twisted Pair
16/2 3 Ft. Pigtail - Distance: Sensor to Control Unit – 2
Miles - Minimum Sensing Speed: Less than 1 RPM
Installation Instructions
- Select the roller or shaft to be monitored. Ensure the roller
is always in contact with the belt. - Affix a target (e.g., key-stock, 1/4-20 Hex Nut) on the roller
or shaft. Do not use notches or dents as targets. - Mount the sensor firmly using hose clamps or U-bolts to prevent
movement. Do not use tape as a fastener. - Position the target so that it passes through the center area
of the sensor face for optimal sensitivity and sensing
distance. - Check that the LED on the sensor blinks proportionally to the
speed of the shaft or roller when moved toward the target. - The effective distance between the sensor and target ranges
from approximately .1 inch to .5 inch based on target size.
FAQ
Q: Can I use a notch or dent as a target for the prox
sensor?
A: No, the sensor must detect the presence of a
target, not an absence of a target like with a notch or dent.
Q: What is the recommended cable for above-ground
applications?
A: Shielded cable is recommended, and its
shield should be attached to earth ground within 2 feet of the
sensor head. In noisy environments, grounding the shield at the
control module can eliminate E.M.I. interference.

Inductive Proximity Type
MODEL 10-7140
INSTALLATION
1. Select the roller or shaft to be monitored. If a roller is to be monitored, be sure it is always contacting the belt.
2. Affix a target on the roller or shaft. The target should be a piece of key-stock, 1/4-20 Hex Nut, etc. (Figure 1) NOTE: The use of a notch or a dent is not an acceptable target for the prox sensor. This sensor must see the presence of a target, not an absence of a target as there would be with a notch or dent.
3. Mount sensor firmly with hose clamps or U-bolts to prevent if from moving or working loose. Tape is NOT recommended as a fastener.
4. Before tightening, check that the target passes through the center area of the sensor face. This will produce the greatest sensitivity and sensing distance. With the roller or shaft spinning, move the sensor toward the target. The LED on the sensor should blink in direct proportion to the speed of the shaft or roller. Effective distance between the sensor and target is approximately .1 inch to .5 inch depending on the size of the target.

**NOTE – Shielded cable is recommended for all above ground applications. The shield of the cable should be attached to earth ground within 2 feet of the sensor head. In severe noise environments, grounding the shield at the control module also, will eliminate any E.M.I. interference.
Note: When mounting sensor on small idler rollers (less than 6 inches in diameter), install a maximum of 2 targets.
