SUCO

Suco - 0167 Pressure Switch

Brass body

The SUCO 0167 is a compact diaphragm-style pressure switch housed in a robust brass body with a HEX‑24 (≈ 0.95) thread interface. It supports maximum voltages up to 42 VAC/DC and handles resistive currents up to 4 A. Field-adjustable across four ranges the switch is available in either normally open or normally closed SPST configurations, with contact deviation as tight as ±0.2 bar for low-range units. Overpressure safety is rated at 35 bar ( 500 psi), with dynamic burst pressures significantly higher (up to 400 bar). It features a durable NBR (Buna-N), EPDM, FKM (Viton®), or silicone diaphragm capable of withstanding media temperatures from –40 °C to +120 °C (depending on material), IP65 protection via a polyamide cap, and a service life of around 1 million cycles at up to 50 bar switching pressure.

The 0167 switch is ideal for monitoring pressures in water systems, pneumatics, hydraulics, and light industrial machinery. Its field-adjustable setpoint allows on-site calibration during installation or maintenance, while the brass housing offers chemical resilience. Typical uses include triggering pump cycles, activating alarms for out-of-range pressures, and protecting against overpressure in applications such as cooling loops, domestic water supply, oxygen or brake-fluid monitoring, and medical or food-service equipment. Available with both spade or screw terminals and in various thread sizes (G¼″, ⅛″ NPT/BSP, M10×1), along with ready-wired or connector-equipped variants, it offers versatile integration into OEM and field systems.
