The Omron D4V-8108Z is a sealed, high-durability limit switch designed for precise mechanical actuation in compact industrial setups. Its adjustable roller lever actuator offers flexibility in sensing positions, making it ideal for systems with moving parts or variable product dimensions. This model supports a 5 A switching load at 250 VAC and delivers an electrical life of 300,000 operations, along with a mechanical life of over 10 million cycles.
The switch operates in harsh conditions, withstanding vibration (10–55 Hz), shock (up to 1,000 m/s²), and temperatures from −20°C to 60°C. It maintains excellent insulation (100 MΩ at 500 VDC), low contact resistance (25 mΩ max.), and complies with IP65 protection, resisting dust and water ingress. The D4V-8108Z is widely used in conveyor systems, machine tools, and automated lines where consistent, adjustable, and space-saving detection is critical.
