Perimeter Seals are sealing solutions designed to create a an airtight fire resistant barrier around the edges and perimeter of fire doors, regular doors, joints and openings. Perimeter seals prevent passage of water, fire and smoke through gaps.

Perimeter Seals can typically last 10 -15 years with annual inspections and maintenance.

Majority of Acoustic seals can last from 10 to 15 years of optimal performance depending on the type of acoustic seal and conditions.

Acoustic seals are designed to reduce sound transmission through gaps, joints and openings between doors, windows and walls throughout the building. They eliminate sound waves which can easily pass through gaps, which enhances the soundproofing system for doors, windows and walls.

Acoustic seals can be used in commercial buildings, residential buildings public buildings. Typically they are installed around doors, windows and brushes.

Acoustic seals can provide noise reduction of up 20db improvements in sound reduction for doors, windows and walls.

Description The A4988 stepper motor driver carrier is a breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 – 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling). Simple step and direction control interface Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection Short-to-ground and shorted-load protection Comes complete with self adhesive heat sink. Technical Specifications Minimum operating voltage: 8 V Maximum operating voltage: 35 V Continuous current per phase: 1 A Maximum current per phase: 2 A Minimum logic voltage: 3 V Maximum logic voltage: 5.5 V Microstep resolutions: 1, 1/2, 1/4, 1/8, 1/16 Size: 0.6″ × 0.8″ Weight: 1.3 g Related
