AH165-TL

What type of component is this?

It is an illuminated pushbutton switch used for operator input and visual indication on industrial control panels. The AH165-TL belongs to the Fuji Electric AH165 oil-tight pushbutton range.

What panel cut-out size is typically used for this type of switch?

This range is designed around a compact 16 mm mounting format, with a typical panel cut-out of approximately 16.2 mm diameter for the operator body.

Is this switch suitable for compact control panels?

Yes. The AH165 range is designed as a finger-size 16 mm command switch series, making it suitable where panel space is limited.

What does the rectangular head style provide?

The rectangular illuminated head provides a clear visual target for operators and allows legends or identification plates to be used for functions such as start, stop, reset, open or close.

Can the lens colour be changed?

Yes. The AH165 illuminated pushbutton range uses replaceable colour chips or lenses, allowing the visual indication colour to be matched to the function of the control.

What protection rating is associated with the oil-tight version?

The oil-tight AH165 series is rated to IP65 at the operator side when correctly installed, helping protect the front of the panel against dust and water ingress.

What contact arrangements are commonly used with this style of pushbutton?

The AH165 pushbutton family supports contact block arrangements such as 1NO + 1NC, 2NO + 2NC and 3NO + 3NC, depending on the complete configuration.

What terminal style is normally used?

Solder/tab terminals are commonly supplied as standard in this range, with wire-wrap terminal variants available for some configurations.

Can this switch be used with illuminated indication circuits?

Yes. As an illuminated pushbutton style, it is intended for circuits where a lamp provides visual status indication through the button lens.

What lamp options are associated with the range?

The AH165 illuminated pushbutton range includes incandescent, LED and neon lamp options depending on the exact configuration and voltage requirements.

What should be considered when replacing the lamp?

Lamp replacement should be carried out using the appropriate lamp removal tool and by following the correct sequence for removing the lens and inner button. Static electricity precautions are especially important when handling high-brightness LED versions.

What operating environment is suitable for this component?

The AH165 series is intended for indoor industrial control applications. The datasheet specifies use within the rated temperature and humidity limits, avoiding condensation and icing.

What is the rated insulation voltage for the related AH165 range?

For the AH165-2 range shown in the same family documentation, the rated insulation voltage is listed as 250 V AC/DC. Exact ratings should always be checked against the full configuration.

What applications is this type of switch commonly used in?

It is commonly used on machine control panels, operator consoles, process equipment and automation panels where a compact illuminated manual control is required.

What accessories may be relevant for installation or maintenance?

Relevant accessories in the AH165 family include colour chips, legend plates, terminal covers, contact blocks, lamp changers, removers and panel mounting tools.

What HS code is appropriate for this component?

A suitable commodity code is 853650, as the item is an electrical switch used for making or breaking electrical circuits.
