Frequently Asked Questions

• What is the main advantage of the 40-inch cable? The 70085-1010-355 reaches distant control panels and avoids cable extensions.
• Can this sensor measure very slow rotations? Yes, it reliably detects speeds as low as 2 RPM.
• Is the cable oil-resistant? Yes, the PVC jacket withstands oil and chemical exposure.
• What torque should I use for mounting? Apply 20-25 Nm torque for secure M18 threaded installation.
• Does the long cable affect signal quality? No, the shielded design maintains signal integrity over the full length.
