Hafner BA 302 02 Ex: red/yellow palm button

Hafner BA 302 02 Ex is a red/yellow palm button for manual operation of a compatible Hafner BAS panel valve. It mounts through a Ø30 mm panel hole; the valve body is selected separately.

Key product details

Manufacturer: Hafner
Product code: BA 302 02 Ex
Type: red/yellow palm button
Actuation: palm button
Actuating force: 8.5 N
Mounting: Ø30 mm panel hole
Material: polyamide with silicone seals
Protection: IP66
Temperature: −60 to +70 °C for the element; observe valve limits

Selection and use

The palm button identifies how the operator applies a manual command. Its 8.5 N catalogue actuation figure helps distinguish it from the other BA 30-series Ex operator styles; the panel should present the chosen control clearly to the user.

The BA 302 02 Ex is the operator part of a BAS panel control. Select the matching BAS valve body and its pneumatic ports separately. The element uses a Ø30 mm panel hole and has IP66 protection; its temperature range is for the element and does not extend the valve’s rating.

Select the button, lever or switch action for the required human interface, then compare the panel hole and the mating valve body before assembly. Keep access around the operator so it can be actuated and maintained. The actual pressure and flow limits come from the separate valve body and pneumatic circuit.

The actuating element is specified for ATEX and IECEx zone 1, 2, 21 and 22 applications; the complete assembly must satisfy its own valve and installation conditions.

Pair Hafner BA 302 02 Ex with a BAS valve whose limits cover the intended environment. Its 8.5 N operator figure and red/yellow palm button action identify the control head; the pneumatic body needs a separate choice.

Applications & Integrations

Applications

Hafner BA 302 02 Ex (SKU BA 302 02 Ex) is the red/yellow palm button for an accessible BA-series pneumatic control. The Ø30 mm operator has a 8.5 N actuation figure and belongs with a matching BAS valve, including installations specified for its Ex marking. Use the chosen head where an operator can reach it, identify its purpose and see the surrounding controls. The BA valve body chosen for the air circuit supplies the switching function; this item supplies the human interface. A different colour or shape can represent a different purchased part even when the panel aperture is the same. The exact product code helps identify the intended component in a spare-parts order.

Integrations

Fit Hafner BA 302 02 Ex (SKU BA 302 02 Ex) through the specified Ø30 mm panel hole and attach a compatible BAS-series panel valve body. The rear coupling must engage the valve while leaving enough clearance for full operator travel and future replacement. Route the compressed-air supply, working lines and exhaust to that separate valve body, not to the operator head. Keep the complete BAS valve and actuation assembly within its approved hazardous-area and temperature conditions; the actuator rating alone does not rate the assembled circuit. Place the controls so a technician can inspect the coupling and remove the head without stressing connected tubing.
