Single-beam Safety Sensor E3ZS
14Pages

Single-beam Safety Sensor Detects Intrusions into Hazardous Areas with a Single Beam and Complies with International Safety Standards. E3ZS For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Be sure to read the “Safety Precautions” on page 13. Features Connect to a G9SP to Create a Type 2 Safety Sensor Connects simply and easily using a wide range of accessories.

Application Examples For gaps in small-sized equipment Protect personnel from the hazards of gaps in small-sized equipment or of semi-automated machinery. The E3ZS is a Human Body Detection Sensor (Type 2) for production equipment. Make sure to use it in combination with an G9SP Safety Controller. When used by itself, the E3ZS conforms to PLc/Safety Category 1 (EN ISO13849-1). No particular safety restrictions apply to the G9SP when used by itself, except the inability to use in human detection safety applications. We recommend using it in Light ON mode and using it with error detection via...

Mutual Interference Prevention Filter (for E3ZS) For use with E3ZS-T81 A. This filter prevents mutual interference by changing the direction of polarized light of the 2 adjacent Emitter/ Receivers. However, when the filter is attached, the maximum sensing distance of the E3ZS is reduced to 1.5 m. Cables with Connectors (Socket and Plug) on Both Ends * Use when connecting an E3ZS-T81A to an F39-CN3 Branch Connector.

*1. Connect the Sensor to an G9SP to use it as a safety device or as part of a safety system. *2. Depending on the wiring, this may turn ON when light is interrupted. For your safety, be sure to connect the pink receiver wire (mode selection input) to 24 VDC to turn ON when light is incident. *3. Electro-Sensitive Protective Equipment *4. Active Opto-electronic Protective Device

Safety Precautions<Single-beam Safety Sensor E3ZS> ^WARNING G9SP is the only Controller that can be used for the E3ZS-T81A/E3FS-10B4DDD (type 2). Normal operation may not be possible if another Single-beam Sensor Controller is used. The Sensor cannot be used as part of a safety system when the mode selection input of the Single-beam Safety Sensor Receiver is connected to 0 V because the Sensor will turn ON when light is interrupted (Dark ON). Be sure to connect the mode selection input to 24 VDC if you want the Sensor to turn ON when light is incident (Light ON). Refer to the website at:...
