Honeywell 942-A4M-2D-K220S is a Series 942 ultrasonic proximity sensor module for non-contact object detection. It determines target presence from reflected ultrasonic energy, allowing sensing where color, transparency or surface appearance can make optical methods difficult.
The model is associated with a sensing distance up to approximately 1500 mm, PNP switching and a 19 to 30 VDC supply class. Actual detection stability depends on target size, angle, material, ambient conditions and the configured switching window.
Ultrasonic sensing can support level presence, material handling and position detection without physical contact. Mounting must keep the acoustic path clear and provide adequate spacing from adjacent ultrasonic devices or strong air turbulence.
Before replacement, match the complete 942-A4M-2D-K220S suffix, connector or cable arrangement, housing, PNP logic, switching function, supply and taught sensing limits. The 942 family contains mechanically similar variants with different outputs and interfaces.

Honeywell 942-A4M-2D-K220S is a Series 942 ultrasonic proximity sensor module for non-contact detection over a nominal range extending to about 1500 mm.
Honeywell 942-A4M-2D-K220S transmits ultrasonic pulses and evaluates the returning echo to provide a PNP switching response when a configured target condition is met.
Honeywell 942-A4M-2D-K220S is associated with Honeywell Series 942 Ultrasonic Sensing. Confirm the installed controller, rack or interface and the complete model before replacement.
For Honeywell 942-A4M-2D-K220S, verify sensing technology (Ultrasonic), product form (Industrial proximity sensor module), nominal sensing distance (Up to 1500 mm) against the installed application.
Install Honeywell 942-A4M-2D-K220S only under the approved site procedure. Isolate applicable power, observe electrostatic precautions, check terminal or connector allocation, and compare the complete nameplate with the removed unit.
Commission Honeywell 942-A4M-2D-K220S by checking the configured channel or sensing function, field wiring, supply, status indications and controller response before returning the loop or machine to service.
No. A similar family code or suffix should not replace Honeywell 942-A4M-2D-K220S until hardware revision, electrical function, terminals, firmware or controller compatibility and application approval have been confirmed.
Provide the complete Honeywell 942-A4M-2D-K220S identification, revision, serial number, installed system, electrical configuration, quantity, destination and a clear nameplate photo.
Check Honeywell manufacturer documentation for Honeywell 942-A4M-2D-K220S and confirm the complete model, revision, installed system, electrical configuration and application requirements before procurement or replacement.
Send the complete Honeywell model, revision, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
