Sensor I/O Connector

Models with Pre-wired Connectors: A Connector is not provided with the Sensor. Be sure to order a Connector separately.

Cable length Sensor I/O Connector model Applicable Proximity Sensors
Straight 2 m XS2F-D421-DD0 E2EC-QC2D1-M1GJ-T
5 m XS2F-D421-GD0
L-shape 2 m XS2F-D422-DD0
