Product Overview
The Omron EE-SX872 2M is a T-shaped slot photomicrosensor from the EE-SX87 series, 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 sensor has a T-shaped body with a 5 mm slot that runs through-beam with a GaAs infrared LED on one side and the phototransistor on the other. Output is NPN open-collector, Light-ON as wired. Maximum load is 100 mA at up to 24 VDC. Supply is 5 to 24 VDC and current draw is 35 mA max. Response frequency is 1 kHz, giving 0.17 ms per detection.
The 2 m cable is a flexible PVC lead wire, oil-resistant. Body size is 19.1 x 31.1 x 12.3 mm in a PBT thermoplastic case, IP50, -25 to +55 degC operating. The standard sensing object is opaque, 2 x 0.8 mm min. For the L-shaped sibling, pick the EE-SX870. For the F-shaped sibling, pick the EE-SX871.
Key Features
- T-shaped slot photomicrosensor with 5 mm slot width and GaAs infrared LED
- NPN open-collector output, Light-ON operation, 100 mA load, 0.17 ms response
- Pre-wired with 2 m flexible PVC cable, oil-resistant jacket
- 5 to 24 VDC supply, 35 mA current, PBT housing, IP50, -25 to +55 degC operating
- SKU: EE-SX872 2M
- Series: Omron EE-SX87 slim compact photomicrosensor
- Voltage: 5 TO 24 VDC
Best-Fit Applications
- End-of-stroke flag detection on a small pneumatic cylinder where the 5 mm slot reads the rod position
- Print-mark registration on a label applicator where the mark breaks the beam at the peel roller
- Pulse counting on a small encoder disc at one pulse per revolution up to 6000 rpm
Buying Checklist
- Pick the EE-SX872 2M for a T-shaped 5 mm slot sensor with NPN output and a 2 m cable.
- Pick the EE-SX870 instead when the bracket geometry calls for an L-shaped body rather than T-shaped.
- Pick the EE-SX872P 2M instead when the cabinet is wired PNP and the slot dimensions match.

FAQ for EE-SX872 2M
What is the Omron EE-SX872 2M used for?
It detects when an object breaks the 5 mm slot on a machine. Typical fits are end-of-stroke detection on a cylinder, label-presence detection on a packaging line, and pulse counting from a small slotted disc on an encoder.
What is the difference between EE-SX872 and EE-SX872A?
Both are T-shaped, 5 mm slot, NPN Light-ON. The -A suffix flips the indicator LED so it lights when the beam is interrupted, not when it is clear. The bare EE-SX872 (and this EE-SX872 2M) lights the LED on incident light.
Does the EE-SX872 2M work with a PNP PLC input?
Not directly -- it is NPN open-collector. For a PNP sibling in the same EE-SX87 series with the same T-shaped body, pick the EE-SX872P 2M.
What is the minimum object the EE-SX872 2M can detect?
An opaque object at least 2 x 0.8 mm. Smaller or translucent flags may not break the beam cleanly and should be tested on the actual line before committing.
