Parker Hannifin PWS-B1887 Pneumatic Components

The Parker PWS-B1887 is a Banjo Socket Assembly pneumatic sensor component used for cylinder position detection via back-pressure sensing within Parker PWS threshold sensor systems. It generates a pneumatic signal from pressure drop at the end of stroke in air cylinders and mounts directly to the cylinder port with a banjo-style fitting; the connection is 1/8" NPT (configuration varies). The thermoplastic body with metal fittings supports 0–150 PSI (system dependent) and operates in an industrial temperature range of -15°C to +60°C, suitable for pneumatic automation, factory equipment, packaging machinery, and OEM pneumatic systems requiring non-contact position feedback and exhaust back-pressure monitoring. Common replacements include Parker PWSB1997 Banjo Socket Assembly, Festo cylinder port sensing adapters, and SMC cylinder-mounted pneumatic sensor fittings.
