The 42CRC-4001 sensor is an Allen-Bradley Photoswitch color registration control and photoelectric sensor. This sensor features an automatic gain sensitivity that helps to control the operation of a machine and that also reduces the need for constant supervision when the background colors change. The 42CRC-4001 sensor is manufactured out of cast aluminum and it comes with an anodized housing. It is powered with a voltage rating of 10 to 30 Volts DC. It comes with a current rating of 70 milliamps maximum and it supports a load of up to 100 milliamps. The 42CRC-4001 sensor has a source output that is the PNP type. It has a sensing range of 12.7 millimeters. The sensing beam has a visible green/red LED and it can be selected by the operators. This LED also helps to show the status of the current application. The response time of the Photoswitch sensor is 250 microseconds.

The 42CRC-4001 Photoswitch photoelectric sensor comes with an IP 67 rated enclosure. For connections, the sensor uses a 5-pin micro QA, and a 2-keyway point. The 42CRC-4001 sensor is equipped with an internal diagnostics system that has an alarm indicator for the operators to indicate the loss of the operating margin that can occur due to changes in contrast, misalignment of the output signals, or other unexpected disruptions. The sensor also features latch and automatic reset functions. It also comes with an automatic output dwell time. The 42CRC-4001 sensor is also well equipped in terms of safety and protection. It features continuous output short circuit protection. The outer body of the sensor is Epoxy-coated and this helps it with corrosion resistance. The sensor is CE marked and certified with the C-Tick, cUL, KC, and UL standards.
