The German FEMA DWAM32 is a robust and reliable electromechanical pressure switch designed for demanding industrial applications. It functions as a critical monitoring and control device, automatically opening or closing an electrical circuit in response to specific pressure thresholds within a system.
**Technical Parameters:**
* **Switch Type:** Single-pole, double-throw (SPDT) changeover contact.
* **Electrical Rating:** Typically 10A at 250V AC or 24V DC, suitable for controlling motors, solenoids, and alarms.
* **Pressure Connection:** Standard G 1/4" female thread, allowing for easy integration into pneumatic or hydraulic systems.
* **Pressure Range:** The DWAM32 is available in several adjustable pressure range variants. Common ranges include 0.5 - 8 bar, 1 - 16 bar, and 5 - 40 bar, covering a wide spectrum of low to medium-pressure applications.
* **Setting Range:** The switching point is precisely adjustable across the entire specified pressure range of the selected model.
* **Hysteresis:** Features fixed hysteresis to prevent rapid cycling of the switch (chatter) when the pressure is near the set point, ensuring stable operation.
* **Housing Material:** The enclosure is constructed from a high-impact, fiberglass-reinforced polyamide, providing excellent resistance to chemicals, oils, and mechanical impact.
* **Diaphragm Material:** The pressure-sensing diaphragm is typically made of NBR (Nitrile Butadiene Rubber), offering good compatibility with air, water, and hydraulic oils.
* **Protection Class:** Rated at IP65, making it dust-tight and protected against water jets from any direction, ideal for use in harsh environments.
* **Operating Temperature Range:** Designed to function reliably within an ambient temperature range of approximately -20°C to +80°C.
**Description and Features:**
The FEMA DWAM32 pressure switch is engineered for precision and durability. Its compact design features a transparent cover, enabling visual inspection of the switching mechanism and contact status without needing to open the housing. The setting scale is clearly marked, facilitating straightforward and accurate adjustment of the actuation pressure.
A key feature is its robust construction, ensuring long-term stability and resistance to vibration, which is common in industrial machinery and mobile equipment. The snap-action switch mechanism provides a crisp, definitive contact operation, minimizing electrical arcing and extending the device's service life
