No need for cable

The 4-axis SDM-20640 amplifier board, designed for microstepping four stepper motors, attaches directly to the 96-pin DIN connector of the controller without any need for a cable. The board is a compact 6.92 inches by 5.10 inches, and each amplifier is able to drive a two-phase bipolar stepper motor operating at 18 to 60V dc. There are four featured settings for the board: 0.5, 1, 2, and 3.5A. Along with current settings, the board has a low-current mode that reduces current power by 75 percent when the motor is at a stop. The drives produce 12,800 steps per revolution for a standard 200-step motor. Galil Motion Control Inc.

Consistent with dependable operation

Rated for one million actuations at their stated dynamic load capacity, the EC5, ED15, ED20, and EC30 clutches from REELL Precision provide dependable timing for motion control. The clutches are capable of accelerating loads from 0 to full speed in less than 3 msec and operate on either 12 or 24V dc, filtered or unfiltered. In addition, the clutches provide torque in one direction only, which permits overrunning, and typically operate at speeds between 100 and 900 rpm with a maximum of 1,400 rpm. There is reportedly almost no slippage at engagement and almost instantaneous disengagement. REELL Precision Manufacturing Corp.


Low friction

The HepcoMotion PDU2 (Profile Driven Unit, size 2) is engineered for applications needing a cost effective solution to fit into a compact space envelope. The belt drive fits into a slotted profile, sealing the unit.
