Abstract

A proximity detector having a housing and issuing an output signal whose state is a function of the position of a target or of the frequency of passage of a target, where the detector parameters can be set by an operator using operator dialog facilities communicating with the detector by dialog signals. The dialog facilities are separated from the detector housing and can be incorporated into a connection block connected to the detector housing by a connecting cable which conveys the dialog signals and the detector output signal.

Claims

1. An apparatus for detecting the proximity of a target comprising:

a housing, said housing containing a proximity detector configured to provide an output signal communicating a position of said target in front of said housing, said proximity detector configured to receive input parameters and adjust operation of said proximity detector based on said input parameters;

a connection block configured to communicate said input parameters to said proximity detector, said connection block separate from said housing; and

a cable having a first end and a second end, said first end removably connected to said housing and said second end connected to said connection block, said cable configured to convey said output signal and said input parameters.

2. The apparatus recited in claim 1, wherein said connection block further comprises a first connector configured to communicate said output signal.

3. The apparatus recited in claim 2, wherein said housing further comprises a second connector configured to removably receive said first end of said cable.

4. The apparatus recited in claim 3, wherein said first connector and said second connector are of a same type.

5. The apparatus recited in any of claims 1 to 4, wherein said connection block further comprises an input element configured to communicate said input parameters to said proximity detector and an output element configured to display said output signal.

6. The apparatus recited in claim 5, wherein said input element comprises a pushbutton and said output element comprises a light emitting diode (LED).

7. The apparatus recited in claim 1, wherein said second end of said cable is molded onto said connection block.

8. The apparatus recited claim 1, wherein said proximity detector comprises an inductive proximity detector.

9. The apparatus recited claim 1, wherein said proximity detector comprises a capacitive proximity detector.

10. The apparatus recited claim 1, wherein said proximity detector comprises a magnetic proximity detector.

11. The apparatus recited claim 1, wherein said proximity detector comprises a photoelectric cell proximity detector.

12. An apparatus for detecting the proximity of a target comprising:

a housing, said housing containing a proximity detector configured to provide an output signal communicating a frequency of passage of said target in front of said housing, said proximity detector configured to receive input parameters and adjust operation of said proximity detector based on said input parameters;

a connection block configured to communicate said input parameters to said proximity detector, said connection block separate from said housing; and

a cable having a first end and a second end, said first end removably connected to said housing and said second end connected to said connection block, said cable configured to convey said output signal and said input parameters.

13. The apparatus recited in claim 12, wherein said connection block further comprises a first connector configured to communicate said output signal.

14. The apparatus recited in claim 13, wherein said housing further comprises a second connector configured to removably receive said first end of said cable.

15. The apparatus recited in claim 14, wherein said first connector and said second connector are of a same type.

16. The apparatus recited in any of claims 12 to 15, wherein said connection block further comprises an input element configured to communicate said input parameters to said proximity detector and an output element configured to display said output signal.

17. The apparatus recited in claim 16, wherein said input element comprises a pushbutton and said output element comprises a light emitting diode (LED).

18. The apparatus recited in claim 12, wherein said second end of said cable is molded onto said connection block.

19. The apparatus recited claim 12, wherein said proximity detector comprises an inductive proximity detector.

20. The apparatus recited claim 12, wherein said proximity detector comprises a capacitive proximity detector.

21. The apparatus recited claim 12, wherein said proximity detector comprises a magnetic proximity detector.

22. The apparatus recited claim 12, wherein said proximity detector comprises a photoelectric cell proximity detector.

23. An apparatus for detecting the proximity of a target comprising:

a housing, said housing containing a detector configured to provide an output signal communicating a position of said target in front of said housing or a frequency of passage of said target in front of said housing, said proximity detector configured to receive input parameters and adjust operation of said proximity detector based on said input parameters; and

input means configured to communicate said input parameters to said proximity detector, said input means separate from said housing;

output means configured to display said output signal; and

a cable having a first end and a second end, said first end removably connected to said housing and said second end connected to said input means, said cable configured to convey said output signal and said input parameters.

24. The apparatus recited in claim 23, wherein said input means comprises a pushbutton and said output means comprises a light emitting diode (LED).
