Omron EE-SPX740 Photomicrosensor
Omron EE-SPX740 is a compact through-beam photomicrosensor using a fixed 3.6 mm slot for target sensing. The transmitting and receiving sections establish a modulated optical path across the gap, and interruption of this path changes the NPN switching condition. Dark-ON operation defines the output response, while the sensor operates from 5 to 24 VDC. Average current consumption is specified at 15 mA maximum and peak consumption at 50 mA maximum. The output supports up to 50 mA load current, and a special connector provides removable electrical integration. A red indicator gives visual operating feedback. The EE-SPX740 provides a compact fixed sensing point within the 3.6 mm grooved sensor range across Omron Grooved Sensor Products.

The Omron EE-SPX740 Photomicrosensor uses a fixed 3.6 mm through-beam slot with modulated light and Dark-ON operation. When a target enters the gap, the optical condition changes and the NPN output communicates the resulting state to compatible control equipment. The unit operates from 5 to 24 VDC. Average current consumption is specified at 15 mA maximum and peak consumption at 50 mA maximum. Output load current is limited to 50 mA, with residual voltage of 1 V maximum at a 50 mA load and 0.4 V maximum at 10 mA. A special connector provides electrical integration, while a red indicator supplies visual status. The holder and case are both specified in polycarbonate.
For an Omron compact grooved photomicrosensor requiring a 3.6 mm gap and Dark-ON switching, the relevant model is the EE-SPX740. Operating temperature is listed from -10 to 55°C, with storage from -25 to 65°C. The sensor supports a defined mechanical target path while keeping transmitting and receiving elements aligned inside one assembly. Its 50 mA maximum load differs from the 80 mA capability of some earlier 3.6 mm SPX models, giving the electrical specification its own profile. The modulated optical arrangement is retained across the stated operating conditions. For a related Dark-ON model with a wider 5 mm slot, see EE-SPX741.
