Product catalog summary

Overview: The document provides comprehensive details on the R51E series rotary position sensors, specifically the SV03 and SV01 series. It stresses the importance of adhering to specified ratings to prevent damage and highlights compliance with EU RoHS regulations.

Part Numbering: The part numbering system includes product ID, series, terminal shape, rotor hole shape/size, total resistance, and packaging. For instance, the SV03 series uses codes like 'A' for SMD type and 'L' for lead type, with resistance values in ohms.

SV03 Series Specifications:

Features include high durability (1 million cycles), Pb-free soldering, and a wide operating temperature range (-40°C to +125°C).
Applications include switches for white goods, digital cameras, automotive switches, car audio, printers, robots, and motor drive units.
Specifications detail total resistance, linearity, effective rotational angle, rotational torque, and life cycle.

SV01 Series Specifications:

Features include excellent resistance materials, high reliability, and ultra-thin size (2.1mm height).
Applications are similar to the SV03 series, with additional emphasis on Au plated terminals.
Specifications cover similar parameters as the SV03 series, focusing on durability and performance under various environmental conditions.

Test Methods:

Rotational life tests involve continuous rotation within specified angles and conditions.
Environmental tests include high and low temperature exposure, humidity load life, shock, and vibration tests.
Linearity is measured as a deviation from an ideal straight line, with specific conditions for testing outlined.

Packaging and Handling: Guidelines are provided for storage, board design, circuit design, mechanical design, system design, and mounting on PCBs, including examples of potential issues and preventive measures.

Compliance and Standards: The sensors comply with EU RoHS standards, and users are advised to approve product specifications before ordering.

Specifications and Testing Conditions: The potentiometer should be tested under specific conditions: 25±2°C temperature, 45-55% relative humidity, and 86-106 kPa atmospheric pressure. Post-soldering tests should occur after 24 hours in a room with 15-35°C and 25-75% RH, except for 'Resistance to soldering heat'.

Storage and Operating Conditions: Store at -10 to +40°C with 30-85% humidity. Avoid corrosive gases, direct sunlight, and use within six months of delivery. Do not use in environments with corrosive gases, liquids, dust, static voltage, or direct sea breeze.

Soldering and Mounting Instructions: Use reflow soldering or soldering iron, not flow soldering. Follow Murata's standard land pattern for reflow soldering. Ensure proper solder amount to avoid insufficient strength or bridging. Avoid contact between the soldering iron and the sensor cover.

Mechanical and Handling Notices: Do not apply excessive force during mounting. Ensure PCB holes match the sensor pins to prevent damage. Avoid warping the PCB.

Design and Circuit Recommendations: Ensure connecting impedance is at least 1M ohm. For data accuracy, install data multiple times and use mean values. Test sensors in mass production systems before use.

Packaging and Dimensions: Details on minimum quantities and dimensions for reels, ammo packs, and trays are provided. Follow specified dimensions for plastic tape and reel.

Mechanical Design and System Precautions: Ensure the shaft inserted into the rotor does not affect product characteristics. Avoid applying non-rotational loads to the bearing. Use high viscosity lubricants and prevent them from entering the product.

Troubleshooting and Preventive Measures: To prevent issues like output voltage linearity deterioration, ensure no excessive load is applied to the bearing. Avoid lubricant ingress to maintain product integrity.

Specifications and Recommendations: The document outlines the specifications for a rotary position sensor, emphasizing the importance of maintaining a connection impedance of at least 1MΩ to reduce sliding noise. It advises against rheostat connections due to high contact resistance and specifies not to apply grease to the shaft, only to gear teeth.

Product Handling and Usage: The product is not sealed, exposing contacts and resistive elements to ambient air, which can lead to corrosion in corrosive gas environments. In such cases, a sealed structure is recommended. Proper alignment of the rotor hole and shaft is crucial to prevent bearing wear and maintain output voltage linearity.

Graph Analysis: Two graphs illustrate the effect of connection impedance on output voltage linearity. A higher impedance (1MΩ) reduces sliding noise compared to a lower impedance (200kΩ).

Standards and Certifications: The product is manufactured in an ISO9001 and ISO/TS16949 certified facility, with no use of ozone-depleting chemicals. It is qualified by Underwriters Laboratories Inc. with the standard qualified number A7924.
