■ Ordering Information E3T-series Sensors, M2-mounting Sensors Sensing method Connection method Sensing distance 1m (Sensitivity Adjustment Unit can be used.) Operation mode Through-beam (Emitter + Receiver) *1 *2 Ultracompact, Ultrathin Photoelectric Sensors with Built-in Amplifiers 300 mm Using the E39-R4 Reflector provided 200 mm [30 mm] *3 The Improved E3T Series Makes Mounting and Installation Simpler and Smoother Suitable for Applications in the Rechargeable Battery Industry Small Cylindrical Sensors *1. The model number of the Emitter is expressed by adding an ”L” to the set model number in the table. Example: E3T-ST11-L 2M The model number of the Receiver is expressed by adding a “D” to the set model number in the table. Example: E3T-ST11-D 2M Orders for individual Emitters and Receivers are accepted. (Modifications are required for some models.) *2. Infra-red models are also aveailable. For details, refer to your OMRON website. *3. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. *4. Models are available either with or without the E39-R37-CA Reflector included. Models with E39-R37-CA Reflector. E3T-SR4@-S Models without Reflector. E3T-SR4@-C Note: The mounting holes on M2-mounting Sensors are SUS301 stainless steel.

New Small Cylindrical Sensors Square Sensor Threaded holes are required in two locations. With Square Sensors: Installation • Time is required to tighten screws. • Mounting brackets are sometimes required. But with Small Cylindrical Sensors: Less Drilling and Tightening Work. Work is reduced because holes do not need to be threaded and there is only one place to tighten. Side-view Sensor Mounted to Horizontal Surface Top-view Sensor Mounted to Vertical Surface Mounting without Brackets. For Through-beam Sensors, both Top-view and Side-view Models are available. Select the shape according to...

Small Cylindrical Sensors With Fiber Sensors: Installation • Space is required for the Amplifier. • Setup and installation are troublesome. • Initial and electrical costs are high. But with Small Cylindrical Sensors: Diffuse-reflective Sensors (with Sensitivity Adjuster) Essentially the Same Size as the Fiber Head. But No Amplifier Is Required. Mounting is possible in narrow spaces where only fiber sensors could previously be used. The built-in amplifier and teach-free operation reduce wiring and setup work. And initial costs and electrical costs are also reduced. No Amplifier Less Work...
