XSZ INDUSTRIAL SENSORS
SZ-M137-85DN Ring Proximity Sensor
A source-listed M137 ring proximity sensor for in-ring detection through an 85 mm hole.
85 mm detection hole10-30 VDC
85 mm in-ring detection
This page contains only the source-listed 85 mm M137 ring proximity sensor selection. Its model matrix provides NPN, PNP, and DC output types, each with NO and NC models.
The supplied drawing shows a 137 x 115.5 x 54 mm housing, four 8.8 mm mounting holes, and marked RL and LED locations. Confirm response time, cable, wiring, and target conditions with XSZ before order.
85 mm source data only
The 105 mm M137 selection is excluded from this page.
Clear output mapping
NPN, PNP, and DC labels are vertically merged, while NO and NC codes remain separate.
Drawing-supported installation
The source drawing provides the housing dimensions, four mounting holes, and indicator locations.
Model selection
Only the supplied 85 mm model codes are retained in this selection table.
