Why Choose the Pizzato FR38B1-D30M2 Safety Door Switch?
The Pizzato FR38B1-D30M2 is a heavy-duty protected door safety switch with positive opening, specifically designed for safeguarding access points in industrial machinery. As part of the advanced Pizzato FR series, this model delivers reliable safety monitoring for doors, guards and access panels in demanding environments.
Featuring a durable technopolymer housing with high resistance to mechanical stress, dust and water ingress, this switch is built for long-term industrial use. The adjustable actuator head allows flexible installation and positioning, while the positive opening mechanism ensures safe disconnection of contacts even in the event of contact welding.
With a 1NC slow-action contact block, the FR38B1-D30M2 is optimised for fail-safe safety circuits. The M20 × 1.5 conduit entry provides straightforward wiring, making it ideal for lift systems, machine guards and industrial access control applications.

Positive Opening Safety for Industrial Protection
The FR38B1-D30M2 uses a positive opening mechanism, ensuring that the normally closed contact is physically forced open when actuated. This guarantees safe disconnection even in fault conditions such as welded contacts, making it essential for safety-critical applications.
Its robust construction and high ingress protection ratings allow it to perform reliably in harsh environments including washdown areas, outdoor installations and heavy industrial machinery.
Typical Applications
- Machine guarding and safety interlock systems.
- Lift and elevator door safety monitoring.
- Industrial access doors and protective enclosures.
- Packaging and processing machinery.
- Automation systems requiring fail-safe door detection.
- Heavy-duty industrial environments with high ingress protection requirements.
