The Vossloh-Schwabe socket type 990612 is an enclosed ceramic socket for lamps with the G9.5 base type. It serves as a connection element and socket in electrical lighting systems, particularly in applications where a stable and heat-resistant connection is required. The socket is designed for mounting in luminaires or other lighting bodies and enables the secure fixation of lamps with a G9.5 base. The construction combines a ceramic socket with a metallic mounting part made of brass, which is mounted using M4 screws. The socket is not equipped with a starter holder, making it suitable for use with fluorescent lamps or other lamp types that do not require a starter.

Socket

The socket is designed as an enclosed ceramic socket, where the ceramic serves as an insulating and heat-resistant material. The socket is designed for lamps with the G9.5 base type, which features a small, two-pole plug connection with a contact spacing of 9.5 mm. The socket is therefore specifically designed for small, compact light sources used in technical or industrial lighting systems. The design as a connection element and socket means that the socket not only holds the lamp but also establishes the electrical connection to the luminaire body.

Technology explained clearly

The socket features an electrical cable with a cross-section of 1.5 mm², made of silicone and glass filler. This material combination ensures high heat resistance and mechanical strength, which is important for use in lighting systems with increased thermal load. The cable is white and features wire end ferrules, enabling a secure and clean connection at the connection point. The total cable length is 145 mm, with 130 mm available as usable cable length. This allows for flexible mounting and adaptation to various luminaire constructions. Mounting is done via M4 screws, which are screwed into the brass housing, ensuring a stable and durable installation.

Compatibility and accessories

The socket is specifically designed for lamps with the G9.5 base type. This base type is commonly used in small, compact light sources, particularly in technical or industrial applications. The socket is not equipped with a starter holder, meaning it is not suitable for fluorescent lamps requiring an external starter. The socket is rated for an operating voltage of 250 V, with the nominal value specified as 12.5/250 T350. This value refers to the electrical load limits of the socket, where T350 indicates the thermal load capacity. The socket is therefore suitable for use in lighting systems with a maximum operating voltage of 250 V.

Mounting and installation

Mounting of the socket is done via M4 screws, which are screwed into the brass housing. The socket is therefore designed for secure fixation in luminaires or other lighting bodies. The usable cable length of 130 mm allows for flexible adaptation to various mounting situations. The wire end ferrules at the cable ends facilitate a secure and clean connection at the connection point. The socket is not equipped with a nipple thread, meaning it is not suitable for threaded mounting. The mounting method is therefore exclusively screw mounting.

Advantages in operation

The use of ceramic as the socket material ensures high insulation capability and heat resistance, increasing the safety and service life of the socket. The silicone and glass filler in the cable provide high mechanical strength and heat resistance, making the socket suitable for use in demanding environments. The wire end ferrules at the cable ends enable a secure and clean connection, increasing the reliability of the electrical connection. The socket is therefore suitable for use in technical and industrial lighting systems where high reliability and safety are required.

Applications

The socket is suitable for use in technical and industrial lighting systems, particularly in applications where a stable and heat-resistant connection is required. The socket is designed for lamps with the G9.5 base type, making it suitable for small, compact light sources. The socket is not equipped with a starter holder, making it suitable for use with fluorescent lamps or other lamp types that do not require a starter.
