JAM NUT
In some applications, there can be a great
deal of impact force between target and
sensor. Thus, it may be necessary to protect
the threaded sleeve from damage. Sleeve
damage could cause the sensor to bind
within the sleeve, affecting sensor perform-
ance. A specially designed jam nut which
screws onto the end of the 18 mm sleeve
provides the required protection.
*High temperature/thermal cycle washdowns may cause loosening of cables to sensor, due to material
incompatibility. Stainless steel or plastic cable nuts are suggested in these applications.
