42SML-7110-QD

Part number 42SML-7110-QD is a photoelectric sensor developed by Allen Bradley within the Photoswitch series. This sensor operates within an input voltage range of 11 to 28V DC, which makes it adaptable for different environments. The maximum current consumption is specified at 46mA. This device features a sensing distance that varies from 10mm up to 7.6 meters (0.39 inches to 25 feet), satisfying various operational requirements in automation and control applications.

With a beam angle of 3 degrees, this sensor concentrates the detection area, enhancing sensitivity and precision. The output format is dual, allowing for either normally open (N.O) or normally closed (N.C) configurations, and is available in both NPN and PNP types. This feature makes it a flexible option for different wiring setups and needs.

The maximum output load is rated at 100mA when operating at 28V DC. A switching speed of 500 microseconds ensures quick response times essential for efficient automation processes. The light source utilized is a visible red LED, offering clear indications in operational settings. The housing is constructed from Valox plastic, providing durability in challenging environments.

For connections, a 4-pin DC micro quick disconnect (QD) allows an efficient and reliable interface. This sensor also supports output logic selection with the option for light operate or dark operate configuration based on application requirements. The built-in reverse polarity protection safeguards against incorrect power supply connections, offering reliability during operation. Lastly, the off-state leakage current is limited to a maximum of 10µA, ensuring minimal interference in sensitive applications.
