The STA11 direct-drive linear actuator comes with a 14-to-232-mm stroke length at a peak force of 92 N and peak velocity of 4.7 m/sec.

Ultraslim Direct-Drive Linear Actuator

The 28-mm mounting center makes a 10-actuator assembly less than 12-in. wide. The built-in solid-state position sensor provides ±12-µm repeatability and a 1-Vpp sin/cos output, eliminating the traditional external encoder and simplifying installation. The thrust-rod diameter is 11 mm while the forcer measures 61 × 26 mm and is rated for 75-V operation. The STA11 is also food safe and meets IP67 wash-down specifications. The unit has the same form factor as regular pneumatic and electric actuators and conforms to international mechanical standards.
