Omron EE-SPX743 Photomicrosensor
Omron EE-SPX743 is a through-beam slot photomicrosensor designed around a fixed 3.6 mm sensing gap. Its transmitting and receiving sections maintain a modulated optical path across the opening, allowing the NPN output state to change when a target interrupts the beam. Dark-ON operation determines the switching response, while operating power is supplied from 5 to 24 VDC. Average current consumption is specified at 15 mA maximum, with peak consumption reaching 50 mA maximum. The output supports a maximum load current of 50 mA, and a special connector provides the electrical interface. A red indicator supplies visual operating status. The EE-SPX743 supports the 3.6 mm slot photomicrosensor range across Omron Sensor Products.

The Omron EE-SPX743 Photomicrosensor uses through-beam slot sensing across a fixed 3.6 mm gap. The sensing position is established across the slot, so an object entering that gap changes the optical path and produces the specified output response. The sensor operates from 5 to 24 VDC and provides an NPN output with Dark-ON switching. Average current consumption is rated at 15 mA max., while peak current reaches 50 mA. The output supports up to 50 mA load current, with residual voltage of 1.0 V max. at 50 mA and 0.4 V max. at 10 mA. A red light indicator provides visual operating status. Its optical signal is modulated, and electrical connection is made through the specified special connector, supporting compact machine integration.
The EE-SPX743 has a polycarbonate case and holder and operates within a stated temperature range of -10°C to 55°C. Storage temperature is -25°C to 65°C, while operating humidity is specified from 5% to 85%. Mechanical resistance includes vibration from 10 to 55 Hz at 1.5 mm double amplitude for two hours along each axis and shock resistance of 500 m/s² three times in each X, Y, and Z direction. The enclosure carries an IP50 rating. Its 3.6 mm slot, NPN output, Dark-ON mode, and connector arrangement suit compact position-sensing points where the target passes through a fixed opening. For a closely related 3.6 mm through-beam model with the same switching mode, refer to the Omron EE-SPX742.
