Note: Sensors with open collectors and different frequencies are available.
*1. Through-beam Sensors are normally sold in sets that include both the Emitter and Receiver.
Orders for individual Emitters and Receivers are accepted.
*2. The difference between the E3S-@@ (@@@) 41 and E3S-@@ (@@@) 42 is in the lens direction when the Sensor is mounted.
For details, refer to the dimensions that are provided on page 10 for the E3S-5E41, page 11 for the E3S-DS30E41, and page 12 for the E3S-5E42 and E3S-DS30E42.
