LHRMTS1-G-WH Equivalent & Substitute Parts

Part Overview

The LHRMTS1-G-WH is a passive infrared wall-mounted occupancy sensor manufactured by Thomas Research Products, part of the LightHAWK2™ series. This sensor combines passive infrared and ultrasonic detection technologies to monitor occupancy across 1000 square feet, with relay output for lighting control applications. The unit operates on 120/277VAC supply and includes manual override functionality. As an active product with RoHS compliance and unlimited moisture sensitivity rating, this sensor serves critical roles in automated lighting and HVAC control systems. Substitute parts are identified when equivalent electrical specifications, mechanical mounting compatibility, and functional output characteristics align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LHRMTS1-G-WH is determined by the following critical parameters:

• Sensor Technology: Passive infrared and ultrasonic dual-technology detection
• Voltage Compatibility: 120/277VAC supply voltage
• Coverage Specification: 1000 square feet detection area
• Output Interface: Relay output for direct load switching
• Mounting Configuration: Wall-mount form factor
• Manual Override Capability: Required for user control
• Compliance Requirements: RoHS compliance status

The substitute part LHMTS1-N-WH from Oslo Switch meets the functional and electrical requirements for direct substitution in applications requiring passive infrared and ultrasonic occupancy sensing with relay output on 120/277VAC circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the LHRMTS1-G-WH and LHMTS1-N-WH are active products with confirmed availability. The primary part (LHRMTS1-G-WH) carries explicit RoHS compliance certification and detailed electrical specifications. Selection between these parts should be based on:

• Availability Requirements: The substitute part LHMTS1-N-WH offers higher current inventory (959 pcs vs. 884 pcs)
• Packaging Needs: Main part supplied in box packaging; substitute supplied in bulk packaging
• Specification Verification: Confirm that the LHMTS1-N-WH meets all voltage, coverage, and output requirements for your specific application before deployment
• Compliance Documentation: Verify RoHS and regulatory compliance documentation for the substitute part with the supplier

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the LHRMTS1-G-WH?

A: The substitute must provide passive infrared and ultrasonic occupancy sensing, operate on 120/277VAC supply, deliver relay output, support wall mounting, include manual override, and maintain RoHS compliance. Coverage area of 1000 square feet and operating temperature range of 0°C to 40°C are also required.

Q: Can the LHMTS1-N-WH be used as a direct replacement in existing installations?

A: The LHMTS1-N-WH is functionally equivalent for occupancy sensing applications. However, verify that all electrical specifications, mounting dimensions, and output characteristics match your circuit requirements before installation.

Q: What is the difference in packaging between the main part and substitute?

A: The LHRMTS1-G-WH is supplied in box packaging, while the LHMTS1-N-WH is supplied in bulk packaging. This affects handling, storage, and inventory management but does not impact functional performance.

Q: Are both parts RoHS compliant?

A: The LHRMTS1-G-WH is explicitly RoHS compliant. Verify RoHS compliance status for the LHMTS1-N-WH with the supplier before procurement.

Q: What voltage ratings do these sensors support?

A: Both sensors are designed for 120/277VAC supply voltage, making them suitable for standard North American commercial and industrial lighting control circuits.
