Focus pluggable interface control device

A focus pluggable interface control device comprising:

• a lens which covers a sensor;
• a mounting plate;
• a mounting plug;
• and a housing,
• wherein the sensor collects control information which has passed through the lens,
• wherein the mounting plate, by way of at least one locating member, is fixed to the sensor by jamming the sensor against the at least one locating member and thereby the sensor is also fixed to the mounting plug,
• wherein the mounting plug is electrically connected to the sensor,
• wherein the mounting plug is provided to mount the focus pluggable interface control device onto the external lamp and to create an electrical connection between the sensor and the external lamp so that the focus pluggable interface control device may control the external lamp,
• wherein the housing is connected to the mounting plate, thereby securing a bottom portion of the lens, and the housing is provided with a first mounting hole through which the lens extends,
• wherein the housing is further provided with at least one second mounting hole,
• wherein a rotatable adjusting member extends through each of the at least one second mounting holes to connect with a corresponding adjusting portion provided on the sensor and the corresponding adjusting portion is formed as an adjustable resistance element,
• wherein an output signal of the sensor for a given control information is adjustable by rotating the rotatable adjusting member.
