DESCRIPTIONS

This sensor is ideal for generating switch-contact count signals from passing

steel or iron castings, weldments, stampings, “Tin-cans”, pulley spokes, etc. A

flux-field, generated by internal permanent magnets is arranged to hold the

SPDT switch contact in the N.C. position. When an external mass of magnetic

material (target) approaches the sensing area, it shunts away a part of this field,

causing the switch contact to transfer to the N.O. position. The distance, at

which this occurs, is called the “Sensing Distance” and it depends on the size,

shape and thickness of the ferrous target. The curve below shows variation of

sensing distance with target area of steel plate, 0.1" or more in thickness. For

very thin sheet steel (0.01" to 0.02") derate sensing distance by 50%. Once the

N.O. switch transfer is made, the target must move away approximately 2 times

the sensing distance to re-establish the original N.C. contact closure.

These switches can be operated at speeds up to 60 counts/sec and have a life

rating of 2-billion operations when used in low-current, low-voltage electronic

counting applications. Operating temperature range is -50° to +120°C.
