SUCO 0166 40804 1032 Pressure Switch Assembly

The SUCO 0166 series diaphragm pressure switch is engineered for compact pressure monitoring in harsh mobile hydraulic and pneumatic systems. It features a robust zinc-plated steel body rated for maximum static overpressure of 300 bar. The adjustment range is factory set between 1 and 10 bar with a tolerance of ±0.5 bar. The sealing diaphragm utilizes NBR (Nitrile Butadiene Rubber) compatible with hydraulic oil, mineral oil, air, and nitrogen. Electrical specification includes a maximum switching voltage of 42 V DC/AC with a normally closed (NC) contact configuration. Connection is via standard 6.3 x 0.8 mm spade terminals (Faston). The process connection is an external NPT 1/8 thread with a hex 24 mm mounting head. Operating temperature range spans -40°C to +100°C. The unit complies with IP65 protection class when mated with appropriate connector. Designed for field-adjustable setpoints, this switch serves as a critical safety and control component in off-highway equipment, industrial power units, and mobile machinery hydraulic circuits. It provides reliable actuation for alarm, shutdown, or control logic functions.
