1. Product Identification & Overview

️· Product: CUI Devices PR13 Relay
️· Series: PR13
️· Type: Power Relay
️· Form Factors/Configurations: Two main configurations are presented:
- 1C (1 Form C): This is a single-pole, double-throw (SPDT) relay. This configuration has a common terminal that switches between two separate terminals.
- 1A (1 Form A): This is a normally open single pole single throw (SPST) relay.
️· Date of Document: August 26, 1982

2. Technical Specifications & Features

️· Compliance: ISO9001, ISO/TS16949, and ISO14001 approved. These are quality management system certifications.
️· Warranty: One-year limited warranty.
️· Critical Component Disclaimer: The relay is *not* approved for use as a critical component in life-support systems.
️· Revision History: The current document is Revision 1.0 (initial release).

3. Dimensional Drawings & PCB Layout (Most Complex Part - Interpretation Below)

These drawings represent the physical dimensions and suggested PCB layout for both relay configurations. I've done my best to decode them based on common engineering practices, but there's a chance of misinterpretation due to the graphic representation style.

General Notes on the Drawings:

️· Units: The dimensions are in millimeters (mm).
️· Tolerance: The general tolerance is ±0.3 mm, unless otherwise specified.
️· "O" Notation: "5-O1.3" likely means "5 x 0.13," and relates to mounting hole specifications.
️· "4-O" similar to above.

1C (1 Form C) Relay Drawing Interpretation:

️· Overall Dimensions: The relay is approximately 19.0 mm wide and has a relevant height/depth.
️· Mounting Holes: It has mounting holes, probably intended for screws.
️· PCB Layout: The drawing provides a suggested PCB layout, showing the position of the relay's terminals and the recommended tracks for connecting it to the circuit board.
- Terminals: The typical terminals would be:
■ Common (COM): The input terminal where the signal is applied.
■ Normally Open (NO): The output terminal that is connected to the common terminal when the relay is energized.
■ Normally Closed (NC): The output terminal that is connected to the common terminal when the relay is *not* energized.

1A (1 Form A) Relay Drawing Interpretation:

️· Overall Dimensions: Similar to 1C.
️· Mounting Holes: Same as 1C.
️· PCB Layout: Shows the suggested PCB layout for this SPST configuration.
- Terminals:
■ Common (COM): Input terminal.
■ Normally Open (NO): Output terminal connected to common when energized.

4. Ordering Information

The document does not explicitly provide ordering information. You's likely have to contact CUI Devices directly or consult their catalogs for part numbers.

Important Considerations:

️· Drawing Style: The drawings are presented in a somewhat unusual, potentially automated graphic style. It can be difficult to read and interpret the precise placement of everything.
️· Contact CUI Devices: For precise specifications, accurate part numbers, and any updates, always refer to the official CUI Devices documentation.
