Panasonic EX-M2 Through-Beam Optical Sensor: Equivalent & Substitute Parts

Part Overview

The Panasonic EX-M2 is a through-beam optical sensor designed for 2-meter (78.7") sensing distance applications with NPN open collector output. This sensor operates across 12V to 24V supply voltage with 1ms response time and IP65 ingress protection, suitable for industrial automation and detection tasks requiring reliable through-beam sensing.

The EX-M2 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new installations where this sensing technology remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Panasonic EX-M2 is determined by the following critical parameters:

• Sensing Method: Must be through-beam configuration
• Sensing Distance: Must match or exceed 78.7" (2m) capability
• Voltage Supply Range: Must accommodate the 12V ~ 24V operating window
• Output Configuration: Must provide NPN output compatible with open collector logic
• Response Time: Must meet or exceed 1ms performance
• Light Source: Infrared technology for consistent through-beam operation
• Connection Method: Cable-based connection for field installation
• Ingress Protection: Must maintain IP65 or higher environmental sealing
• Operating Temperature: Must support the -10°C ~ 60°C range or broader

The Omron E3H2-T2C1S 2M satisfies all substitution criteria through equivalent through-beam sensing, matching 2-meter distance, compatible voltage supply (10V ~ 30V encompasses 12V ~ 24V), NPN output with selectable dark-on/light-on functionality, 1ms response time, infrared 880nm light source, cable connection, IP67 ingress protection (exceeds IP65), and extended operating temperature range (-25°C ~ 50°C).

Engineering Selection Recommendations

The Omron E3H2-T2C1S 2M is a direct functional substitute for the obsolete Panasonic EX-M2. Both sensors are RoHS compliant and share identical sensing distance and response time specifications. The Omron part offers an extended voltage supply range (10V ~ 30V) that fully encompasses the EX-M2 operating window, enhanced ingress protection (IP67 versus IP65), and selectable output logic (dark-on/light-on) providing greater application flexibility.

The Omron E3H2-T2C1S 2M is currently in active production status with confirmed inventory availability, ensuring long-term supply chain reliability for replacement and new deployment scenarios.

Frequently Asked Questions (FAQ)

Q: Can the Omron E3H2-T2C1S 2M directly replace the Panasonic EX-M2 in existing installations?

A: Yes. Both sensors share identical sensing distance (2m), response time (1ms), and NPN output configuration. The Omron part operates across a wider voltage range (10V ~ 30V) that fully covers the EX-M2 specification (12V ~ 24V). Wiring and mounting compatibility must be verified for your specific application.

Q: What is the difference between the output configurations?

A: The Panasonic EX-M2 provides fixed NPN open collector output. The Omron E3H2-T2C1S 2M offers selectable dark-on/light-on output logic, allowing configuration of the sensor response to match your control system requirements without hardware changes.

Q: Does the higher IP67 rating of the Omron sensor provide additional benefits?

A: IP67 ingress protection exceeds the EX-M2 IP65 rating, offering enhanced resistance to dust and temporary water immersion. This provides greater environmental tolerance in demanding industrial settings.

Q: Are both sensors RoHS compliant?

A: Yes. The Panasonic EX-M2 is explicitly RoHS compliant. The Omron E3H2-T2C1S 2M maintains active product status, indicating current manufacturing compliance with RoHS requirements.

Q: What is the cable length specification for the Omron substitute?

A: The provided data specifies the Panasonic EX-M2 cable length as 118.10" (3m). Cable length for the Omron E3H2-T2C1S 2M should be confirmed with the manufacturer or distributor for your specific application requirements.
