Product Overview
The Omron E39-R1S is a rectangular retro-reflector for photoelectric sensors from the E39 accessory family It is manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
The reflector has an ABS base with an acrylic reflective surface. It is 59.9 mm tall, 40.3 mm wide and 7.5 mm deep, with two M3 mounting holes diagonal across the base.
For a small lens attachment that mounts in front of the sensor, pick the E39-L98. Key specs: Shape Rectangular; Dimensions 59.9 (H) x 40.3 (W) x 7.5 (D) mm; Mounting Two M3 screws diagonal on 50 mm centres; Sensing Distance 100 mm to 4 m with E3Z-R / E3Z-B MSR; 3.7 m with E3F2-R4; Directional Angle 30 degrees; MSR Compatibility Yes (polarising filter); Operating Temperature -25 to +55 degrees C; Storage Temperature -40 to +70 degrees C.
Key Features
- Rectangular retro-reflector, 59.9 x 40.3 x 7.5 mm, ABS base + acrylic surface
- Two M3 diagonal mounting holes, MSR polarising filter compatible
- 100 mm to 4 m range with E3Z-R series, 100 mm to 3.7 m with E3F2-R4
- IP67, -25 to +55 degrees C, 30 degree directional angle
- SKU: E39-R1S
- Series: Omron E39-series retro-reflective reflector
Best-Fit Applications
- Carton detection on a sortation conveyor where the 4 m range covers the belt width and the MSR filter rejects shiny parcel tape
- Pallet presence check at a stretch-wrapper infeed where the reflector mounts on the opposite ram at 3 m distance
- Spare reflector for an existing E3Z-R86 retro sensor where the original E39-R1S has been scuffed by forklift traffic
Buying Checklist
- Pick the E39-R1S for a 40x60 mm rectangular reflector compatible with E3Z-R and E3Z-B MSR sensors.
- Pick the E39-R7 instead when the panel needs a round 84 mm reflector for the same E3Z-R sensor.
- Pick the E39-L98 instead when the application needs a lens attachment that mounts in front of the sensor (not a reflector).

FAQ for E39-R1S
Is the E39-R1S compatible with all Omron retro-reflective sensors?
Yes for the E3Z-R, E3Z-R-K, E3Z-B61 / B66 / B81 / B86, E3Z-B62 / B67 / B82 / B87, E3ZM-R, E3ZM-CR, E3F2-R4, E3FZ-R and E3FR-R families. It also works with E3FA / E3FB retro sensors in the E3FA-B / E3FB-B series.
What does the MSR function mean on the E39-R1S?
MSR (mirror surface rejection) is a polarising filter on the sensor receiver. Reflective surfaces like foil or polished metal bounce light back without depolarising it, so the sensor ignores them. Only the E39-R1 / R1S reflector depolarises the beam and triggers the sensor.
How far can the E39-R1S be mounted from the sensor?
100 mm to 4 m with an E3Z-R or E3Z-B MSR sensor. 100 mm to 3.7 m with the E3F2-R4. The directional angle is 30 degrees, so a 10 mm offset at 4 m range stays within the beam width.
