OMRON Photoelectric Sensor, 2W Power Consumption, -25°C to +55°C Operating Temperature - E3JM Series - E3JMR4M4G
For pinpoint object detection in your industrial equipment, count on this photoelectric sensor from OMRON. It's a retroreflective type so it emits a beam to a reflector and picks out opaque items that interrupt the ray. This makes it useful for machine speed control and safety functions. The unit's ABS case protects it from the wear and impact that come with harsh environments, meaning it's a durable workmate. With a 4m detection range, it's the one to grab for setups involving large machines. To boost safety, the device's 2kV dielectric strength shows it handles high voltages without breaking a sweat.
Features & Benefits
• Consumes just 2W of power during operation to ensure energy efficiency
• MSR (mirror surface rejection) function uses a polarising filter to reduce false triggering
• IP66 rating means it's protected from dust and strong water jets
• LED indicator for easy monitoring and fault diagnosis
• Supply Voltage 24-240VDC and 100-240VAC
• Includes a mounting bracket and cable gland for simple installation
