This is an aluminum bolt-on arm for 995, 996, 946 servos. It is great for application where plastic arms are simply too weak for the amount of torque the servo is outputting. It is great for RC and DIY projects with torque. Two m2 screws are included to fasten and clamp the arm into the servo. The mounting threads are M3 sized (M3 screws are not included).

This solenoid in particular is nice and strong, with a 40mm long body and a 'captive' armature with a return spring. This means that when activated with up to 12VDC, the solenoid moves and then the voltage is removed it springs back to the original position, which is quite handy. Many lower cost solenoids are only push type or only pull type and may not have a captive armature (it'll fall out!) or don't have a return spring. This solenoid has 4xM3 (metric) threaded holes in the bottom for easy mounting.

This 14x4mm buzzer will require a 100 ohm resistor on the red wire to a PWM source or ac voltage in order to generate a tone. Unlike the active buzzer that only requires a constant voltage this passive buzzer will need a microcontroller to help it run. We recommend using this product with an Arduino Uno. Excellent for a simple project use as the buzzer not that loud compared to the BUZ-120.
