Key Parameters

Substitute Part Grouping Explanation

The SA2E-BP3C is identified as the manufacturer-recommended substitute for the SA1E-BP1C. Substitution eligibility is determined by the following critical parameters:

• Sensing method: Both sensors employ reflective, background suppression technology
• Output configuration: Both provide PNP output
• Supply voltage range: Both operate within 10V ~ 30V
• Light source: Both use Red LED
• Connection method: Both utilize connector-based interfaces
• Ingress protection: Both maintain IP67 rating
• Compliance: Both are ROHS3 compliant

The SA2E-BP3C extends the sensing distance capability to 0.394" ~ 13.780" (10mm ~ 350mm) and improves response time to 500µs, while maintaining backward compatibility with the core electrical and mechanical parameters of the SA1E-BP1C.

Parameter Comparison

Engineering Selection Recommendations

The SA2E-BP3C is the active, manufacturer-recommended substitute for the obsolete SA1E-BP1C. Both sensors maintain identical supply voltage ranges, output configurations, light source specifications, and ingress protection ratings. The SA2E-BP3C is ROHS3 compliant and REACH affected, ensuring compliance with current regulatory requirements.

The SA2E-BP3C provides enhanced performance characteristics, including extended sensing distance range and faster response time, while preserving electrical and mechanical compatibility with applications originally designed for the SA1E-BP1C.

Frequently Asked Questions (FAQ)

Q: Can the SA2E-BP3C directly replace the SA1E-BP1C in existing applications?

A: Yes. Both sensors share identical supply voltage specifications (10V ~ 30V), PNP output configuration, Red LED light source, and IP67 ingress protection. The M8 connector interface on the SA2E-BP3C is compatible with standard connector-based installations.

Q: What are the key differences between these sensors?

A: The SA2E-BP3C extends the sensing distance range from 20mm ~ 200mm to 10mm ~ 350mm and reduces response time from 1ms to 500µs. The SA2E-BP3C also provides Dark-ON/Light-ON output options and operates across a wider temperature range (-30°C ~ 55°C versus -25°C ~ 55°C).

Q: Why is the SA1E-BP1C classified as obsolete?

A: The SA1E-BP1C has been discontinued by IDEC. The SA2E-BP3C represents the current active product line for reflective, background suppression optical sensors in this category.

Q: Are there any compatibility concerns with the connector interface?

A: The SA2E-BP3C uses an M8 connector interface, which is a standard industrial connector type. Verify that your application's connector receptacle is compatible with M8 specifications.

Q: Do both sensors meet the same regulatory compliance standards?

A: Both sensors are ROHS3 compliant. The SA2E-BP3C is additionally REACH affected, reflecting current regulatory requirements for active products.
