Spamel ST22-1417RO2 Lamp Holder for BA9s Bulb 24V AC

The Spamel ST22-1417RO2 is a professional-grade lamp holder engineered specifically for BA9s base bulbs operating on a 24V AC power supply. This component serves as a critical element in industrial control panels, automation systems, and signaling equipment, ensuring a secure and stable connection for indicator lights. Designed for durability and ease of integration, this holder provides reliable electrical contact, making it an essential part of modern control infrastructure.

Advantages

The primary advantage of this lamp holder is its robust construction, which is tailored for demanding industrial environments where vibration and mechanical stress are common. By utilizing a standardized BA9s interface, it offers broad compatibility with various signaling bulbs, allowing operators to select the specific light intensity or color required for their unique application. The 24V AC compatibility ensures it integrates seamlessly into standard low-voltage control circuits, while the design facilitates quick installation and maintenance within control cabinets.

Suitable for

• Industrial control panels and automation cabinets
• Signaling and warning light systems
• Machine status monitoring displays
• Low-voltage electrical control circuits

When it may not be suitable

This lamp holder is not designed for direct connection to high-voltage mains power and must be used strictly within the specified 24V AC range. It is also not suitable for outdoor environments without an additional protective enclosure, as it lacks inherent weatherproofing against moisture or dust ingress.

Key specifications

• Base type: BA9s
• Operating voltage: 24V AC
• Application: Industrial signaling and control
• Mounting: Panel mount

How to use

To install the Spamel ST22-1417RO2, mount the holder into the designated cutout on your control panel or enclosure, ensuring it is securely fastened. Connect the electrical leads to the terminals according to your circuit diagram, verifying that the power supply is set to 24V AC. Once the holder is fixed and wired, insert a compatible BA9s bulb into the socket by aligning the pins and rotating it slightly to lock it into place. Always ensure the power is disconnected during the installation or replacement of the bulb to prevent electrical hazards.

What to consider before purchase

• Verify that your control system provides a 24V AC power supply.
• Ensure the panel cutout dimensions match the mounting requirements of the holder.
• Confirm that you have a compatible BA9s bulb available, as it is not included with this unit.

Usage recommendations

Regularly inspect the electrical connections and the bulb socket for signs of oxidation or wear, especially in high-vibration environments, to maintain optimal signaling performance.
