RES20-100-200-Z Rotary Encoder Optical - Equivalent & Substitute Parts

Part Overview

The RES20-100-200-Z is an optical rotary encoder manufactured by Nidec Components Corporation, designed for applications requiring precise rotational position feedback. This encoder delivers 100 pulses per revolution with quadrature (incremental) output, operating at 5V supply voltage with user-selectable orientation and panel mount configuration. The product is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent mechanical and electrical parameters are maintained across the Nidec RE series, allowing for component interchangeability in system designs where resolution requirements permit.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the Nidec RE series maintain compatibility based on the following critical parameters:

• Encoder Type: Optical (consistent across all substitutes)
• Output Type: Quadrature (Incremental) (consistent across all substitutes)
• Voltage Supply: 5V (consistent across all substitutes)
• Actuator Type: Shaft (consistent across all substitutes)
• Mounting Type: Panel Mount (consistent across all substitutes)
• Orientation: User Selectable (consistent across all substitutes)
• Termination Style: PC Pin (consistent across all substitutes)
• Series: RE (consistent across all substitutes)

The RES20-50-200-Z is qualified as a substitute part where system design permits operation at 50 pulses per revolution instead of 100 pulses per revolution. This resolution difference is the sole distinguishing parameter between the main part and its substitute. All other mechanical, electrical, and compliance characteristics remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the RES20-100-200-Z and RES20-50-200-Z are active production parts from Nidec Components Corporation with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts depends solely on the rotational resolution requirement of the application. The RES20-100-200-Z provides 100 pulses per revolution, while the RES20-50-200-Z provides 50 pulses per revolution. All other mechanical, electrical, and environmental specifications are equivalent. Both parts are suitable for panel mount applications with 5V supply operation and user-selectable orientation configuration.

Frequently Asked Questions (FAQ)

Q: Can the RES20-50-200-Z be used as a direct replacement for the RES20-100-200-Z?

A: The RES20-50-200-Z is mechanically and electrically compatible with the RES20-100-200-Z. However, it operates at 50 pulses per revolution instead of 100 pulses per revolution. Substitution is valid only if the application can function with this lower resolution output.

Q: What is the primary difference between these two encoder models?

A: The primary difference is the pulses per revolution specification. The RES20-100-200-Z delivers 100 PPR, while the RES20-50-200-Z delivers 50 PPR. All other parameters including encoder type, output type, supply voltage, mounting configuration, and termination style are identical.

Q: Are both parts available in the same packaging format?

A: Yes, both the RES20-100-200-Z and RES20-50-200-Z are supplied in Tray packaging.

Q: Do both encoders meet the same compliance standards?

A: Yes, both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and are currently active in production status.

Q: What supply voltage is required for both encoder models?

A: Both encoders operate at 5V supply voltage.
