Festo
5078949
Linear actuator DFPI-100- -
The Festo part number 5078949 is an ISO 15552 industrial component featuring a 100 mm piston diameter, a 100 valve actuator size, and a stroke range from 40 mm to 990 mm. This double-acting unit utilizes a piston, piston rod, tie rod 1, and cylinder barrel structural design with no cushioning and allows for any mounting position across an operating pressure of 0.3 MPa to 0.8 MPa (3 bar to 8 bar, 43.5 psi to 116 psi) at a nominal operating pressure of 0.6 MPa (6 bar). Position sensing is provided by an integrated linear potentiometer operating on a potentiometer measuring principle with reverse polarity protection, a two-wire power supply ranging from 9 V to 30 V DC, a 4 - 20 mA analog output, a 0.1 µA recommended contact current, and a 10 mA max. short-time slider current, backed by RCM compliance mark and KC-EMV certifications.
