Equivalent & Substitute Parts for SICK, Inc. 1044705 Optical Sensor

Part Overview

The SICK, Inc. 1044705 is an obsolete retroreflective optical sensor designed for detecting objects within a sensing range of 3.937" to 118.110" (100mm to 3m). Its output configuration is PNP with selectable Dark-ON/Light-ON functionality, powered by a 10V ~ 30V supply, and utilizes a Red LED as the light source. The device features M12, 4POS connector termination and is rated IP67 for ingress protection. Due to its discontinued status and current inventory limitations, finding alternative models with matching electrical and mechanical specifications is necessary for ongoing applications and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for retroreflective optical sensors is based solely on matching these key parameters: sensing method (retroreflective), sensing distance (3.937" ~ 118.110" [100mm ~ 3m]), voltage supply (10V ~ 30V), output configuration (PNP, Dark-ON/Light-ON selectable), light source (Red LED), connection method (Connector, M12, 4POS), ingress protection (minimum IP67), and suitable operating temperature range. Only parts meeting all listed criteria are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SICK, Inc. 1044705 is obsolete, while the Omron Automation and Safety E3RA-RP21 is active and compliant with ROHS3 and REACH, with a listed MSL of 1 (Unlimited). Both parts share overlapping electrical, mechanical, and environmental characteristics as summarized above. For continuity in the Optical Sensors product category where compliance and supply are required, the E3RA-RP21 meets the provided criteria. Both parts are classified under ECCN EAR99 and HTSUS 8541.49.8000.

Frequently Asked Questions (FAQ)

Q1: What criteria must be met when substituting an obsolete optical sensor part number like 1044705?
A1: Substitution is strictly based on matching: sensing method, sensing distance, voltage supply, output configuration, light source type, connection method, ingress protection rating, and operating temperature range.

Q2: Are there any differences between the connection methods or environmental ratings for the listed alternatives?
A2: Both the SICK, Inc. 1044705 and Omron Automation and Safety E3RA-RP21 use Connector, M12, 4POS. The substitute, E3RA-RP21, offers additional ingress protection (IP69K) and a slightly wider temperature range (-25°C ~ 55°C).

Q3: How does product status affect engineering selection for replacement optical sensors?
A3: The main part (1044705) is obsolete; substitute parts must be active and meet compliance standards to ensure ongoing support and availability in inventory systems.

Q4: Are there packaging or moisture sensitivity considerations between these models?
A4: Both parts are supplied in bulk packaging. The E3RA-RP21 specifies moisture sensitivity level (MSL 1, Unlimited), while the 1044705 is listed as not applicable.

Q5: How do compliance certifications impact equivalence selection in this category?
A5: Certifications like ROHS3 and REACH, as well as ECCN and HTSUS correspondences, are considered for regulatory and supply chain requirements but do not affect core electrical or mechanical compatibility when parameters are otherwise matched.
