## Abstract

A housing part (10) for a sensor has a transparent, hollow base body which has a toothing (14) in the form of a straight-toothed gearwheel in a circular-cylindrical emission region on its lateral surface. A circuit board of the sensor is partially arranged in the housing part (10). The circuit board has at least one light source which faces the emission region.

## Claims

### Claim 1

Housing part for a sensor, said housing part comprising:
a transparent, hollow base body having a toothing in the form of a straight-toothed gearwheel in a circular-cylindrical emission region on a lateral surface of the housing part.

### Claim 2 (depends on 1)

The housing part according to claim 1, wherein the hollow base body contains at least one light-diffusing filler.

### Claim 3 (depends on 1)

The housing part according to claim 1, wherein, the toothing is delimited on the lateral surface by a rough structure.

### Claim 4 (depends on 3)

The housing part according to claim 3, wherein the rough structure extends through at least one tooth gap of the toothing.

### Claim 5 (depends on 1)

The housing part according to claim 1, further comprising a coupling element having a V-shaped cross-section on an interior wall of the emission region.

### Claim 6

A sensor said sensor comprising:
a circuit board partially arranged in a housing part, the housing part having a transparent, hollow base body having a toothing in the form of a straight-toothed gearwheel in a circular-cylindrical emission region on a lateral surface of the housing part,
wherein the circuit board has at least one light source which faces the emission region.

### Claim 7 (depends on 6)

The sensor according to claim 6, wherein the light source has two colours.

### Claim 8 (depends on 6)

The sensor according to claim 6 wherein the housing part has a coupling element having a V-shaped cross-section on an interior wall of the emission region and the at least one light source faces the coupling element.

### Claim 9 (depends on 6)

The sensor according to claim 6, wherein the circuit board is partially arranged in a housing pipe, wherein the housing pipe is connected to the housing part by means of a connecting region of the housing part.

### Claim 10 (depends on 9)

The sensor according to claim 9, wherein the circuit board has electrical plug contacts arranged in a plug region of the housing part and extend through openings of a closing element formed as one part with the housing part, wherein the emission region is arranged between the plug region and the connecting region.

### Claim 11 (depends on 6)

The sensor according to claim 6, wherein the hollow base body contains at least one light-diffusing filler.

### Claim 12 (depends on 6)

The sensor according to claim 6, wherein the toothing is delimited on the lateral surface by a rough structure.

### Claim 13 (depends on 12)

The sensor according to claim 12, wherein the rough structure extends through at least one tooth gap of the toothing.
