Product Overview
The Omron E2S-W25 1M is a miniature rectangular inductive proximity sensor from the E2S 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 detects ferrous and non-ferrous metal targets up to 2.5 mm from the top sensing face of the 7.4 x 8 x 23 mm polyarylate housing. Output is PNP normally open on a 3-wire DC circuit. Supply is 10 to 30 VDC, max load 100 mA at 30 VDC, 2 V max residual voltage. Response is 1 kHz with 10% hysteresis.
The 1 m PVC pre-wired cable exits the rear of the rectangular body. Mounting uses an M2.5 or M3 screw through a flat bracket; the yellow operation LED shows the switch state. IP67, -25 to +70 C. The E2S-W23 is the NPN NO version of the same body; the E2B-S08KN04-MC-B1 is the M8 PNP upgrade for higher switching frequency.
Key Features
- E2S-series miniature rectangular inductive proximity sensor, top-surface detection, unshielded, 2.5 mm nominal sensing distance
- DC 3-wire PNP normally open, 10-30 VDC supply, 100 mA max load at 30 VDC, 2 V max residual voltage, 1 kHz response frequency
- 7.4 (W) x 8 (H) x 23 (D) mm polyarylate housing, yellow operation LED, 10% hysteresis
- 1 m PVC pre-wired cable, IP67, -25 to +70 C operating, 35 to 95% RH non-condensing, mounts via M2.5 / M3 bracket screws
- SKU: E2S-W25 1M
- Series: Omron E2S-series miniature rectangular inductive proximity sensor
- Voltage: 10 TO 30 VDC
Best-Fit Applications
- Small parts-present detection on a desktop SMT pick-and-place where the 7.4 x 8 x 23 mm body fits between component feeders
- Top-mounted tool position check on a small robotic gripper that needs a non-flush 2.5 mm sensor on a flat bracket
- Spare replacement on a coin-counting machine where the previous E2S-W23 NPN body must be replaced with a PNP unit on the same wiring harness
Buying Checklist
- Pick the E2S-W25 1M for a miniature rectangular unshielded PNP NO inductive sensor at 2.5 mm on a 1 m PVC cable for tight-mounting fixtures.
- Pick the E2S-W23 instead when the controller input expects an NPN normally open signal on the same 7.4 x 8 x 23 mm body.
- Pick the E2B-S08KN04-MC-B1 2M instead when the bracket needs an M8 shielded PNP NO sensor at 4 mm with higher IP69K washdown rating.

FAQ for E2S-W25 1M
What is the Omron E2S-W25 1M used for?
It is a miniature rectangular inductive proximity sensor for top-surface metal detection on tight-mounting fixtures. The 7.4 x 8 x 23 mm body fits where M8 or M12 cylindrical sensors do not, such as between component feeders or on a robotic gripper bracket.
E2S-W25 1M vs E2S-W23 - what is the difference?
The E2S-W25 1M is PNP normally open. The E2S-W23 is the NPN normally open version of the same 7.4 x 8 x 23 mm body, same 2.5 mm range, same 1 m PVC cable. Pick the 25 for PNP controllers and the 23 for NPN.
Is the E2S-W25 1M shielded?
No. The sensor is unshielded (non-flush), so it must be mounted with clearance around the sensing face to avoid metal derating the 2.5 mm sensing distance. A flat bracket with M2.5 or M3 screws is the standard mount.
What is the IP rating of the E2S-W25 1M?
IP67. The sensor withstands temporary immersion in water but is not rated for high-pressure hot water washdown. Operating temperature is -25 to +70 C in 35 to 95% RH non-condensing ambient.
Can the E2S-W25 1M detect non-ferrous metals?
Yes, but at a reduced sensing distance. The 2.5 mm range is specified on mild steel; stainless steel, brass, copper, and aluminium all trigger at lower distances. For mixed-metal applications, the published correction factor from the datasheet should be applied.
