81921912 is a miniature pneumatic position detector designed for precise actuation and control in industrial automation systems. It features a lever with roller bearing actuation mechanism and operates across a pressure range of 0.1 to 8 bar with an orifice diameter of 2.7 mm and flow rate of 200 NI/min at 6 bars. The detector delivers an actuation force of 18 N at 6 bars and maintains mechanical reliability with a life expectancy exceeding 10 million operations. Operating over a temperature range of -5°C to +50°C, this all-metal pneumatic device is ideal for position sensing, limit switching, and automated machinery control where compact size and pneumatic logic integration are required.
