Mechanically operated valve with roller-lever arm designed for position detection and pneumatic signal triggering in automated systems. Features zero power consumption operation and positive tactile feedback during actuation. The hardened stainless steel roller reduces wear during repeated contact with machine cams or workpieces.
- Position verification in linear actuator end-stops
- Carton box folding machine sequence control
- Conveyor belt package presence detection
- Textile machinery thread tension monitoring
- Safety interlock systems in press brakes
Installation guidelines:
Mount lever arm perpendicular to actuator motion path. Adjust roller position with
0.5-1mm pre-travel for reliable switching. Lubricate pivot point quarterly with
ISO VG32 hydraulic oil. Avoid lateral forces exceeding 5N on lever arm.
