Omron EE-SB5M Optical Sensor - Equivalent & Substitute Parts

Part Overview

The Omron EE-SB5M is a reflective, diffuse optical sensor designed for white paper detection at a fixed sensing distance of 0.197" (5mm). This module features NPN open collector output with light-ON configuration, operates on 5V to 12V supply voltage, and includes external sensitivity adjustment capability. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The Omron EE-SY672 qualifies as a direct substitute for the EE-SB5M based on the following critical parameters:

Matching Core Specifications:

• Sensing method: Reflective (both diffuse and adjustable reflective)
• Sensing object: White paper detection
• Sensing light: Infrared
• Mounting type: Solder
• Package type: Module, Connector
• Output type: NPN configuration with selectable output modes

Compatibility Factors:

• Sensing distance range: EE-SY672 covers 0.039" ~ 0.197" (1mm ~ 5mm) adjustable, which encompasses the fixed 5mm distance of EE-SB5M
• Supply voltage: EE-SY672 operates at 5V ~ 24V, which includes the EE-SB5M operating range of 5V ~ 12V
• Current consumption: EE-SY672 at 40 mA is within acceptable tolerance relative to EE-SB5M at 36 mA
• External sensitivity adjustment: Both models support this feature

Engineering Selection Recommendations

The EE-SY672 is the appropriate substitute for the obsolete EE-SB5M based on product lifecycle and regulatory compliance:

Product Status Justification: The EE-SB5M is obsolete, whereas the EE-SY672 is active and currently in production. This ensures long-term availability, ongoing manufacturer support, and access to technical documentation.

Regulatory Compliance: The EE-SY672 is ROHS3 compliant and REACH affected, indicating compliance with current environmental and safety regulations. The EE-SB5M REACH status is unaffected, reflecting its legacy status.

Functional Compatibility: Both sensors operate within the same infrared reflective detection principle for white paper. The EE-SY672's adjustable sensing distance range (1mm ~ 5mm) accommodates the fixed 5mm specification of the EE-SB5M. The selectable output configuration (Dark-ON/Light-ON) of the EE-SY672 provides operational flexibility while maintaining NPN open collector compatibility.

Supply Voltage Consideration: The EE-SY672 accepts 5V ~ 24V supply, which fully encompasses the EE-SB5M operating range of 5V ~ 12V. Existing power supply designs require no modification.

Frequently Asked Questions (FAQ)

Q: Can the EE-SY672 directly replace the EE-SB5M in existing designs?

A: Yes. Both sensors share identical sensing methods (reflective infrared), target objects (white paper), mounting types (solder), and package configurations (module with connector). The EE-SY672 operates within the voltage and current parameters of the EE-SB5M and requires no circuit redesign.

Q: What is the key difference in sensing distance between these two models?

A: The EE-SB5M has a fixed sensing distance of 0.197" (5mm). The EE-SY672 provides an adjustable range of 0.039" ~ 0.197" (1mm ~ 5mm). This allows the EE-SY672 to be configured to match the EE-SB5M's 5mm specification through external sensitivity adjustment.

Q: Does the EE-SY672's selectable output mode affect compatibility?

A: No. The EE-SY672 output can be configured for Light-ON operation, which matches the EE-SB5M's fixed Light-ON configuration. The Dark-ON option provides additional flexibility for applications requiring inverted logic.

Q: Are there packaging differences between these sensors?

A: Both models use identical packaging: Module with Connector, Solder mounting type. No mechanical or connector modifications are required for substitution.

Q: What is the current consumption difference?

A: The EE-SB5M draws 36 mA, while the EE-SY672 draws 40 mA. This 4 mA difference is negligible for most power supply designs and does not require circuit modifications.

Q: Is the EE-SY672 available in the same packaging as the EE-SB5M?

A: The EE-SB5M packaging is listed as "-" (not specified). The EE-SY672 is available in Bulk packaging. Both use Module, Connector package types for the sensor itself, ensuring mechanical and electrical compatibility.
