A new eight-page white paper from Electro Cam (Roscoe, IL) describes how PLCs and programmable limit switches (PLSs) differ. Describes how PLCs are designed for low-speed processes such as receiving input signals from sensors and limit switches and sending output signals to actuators, solenoid valves, motors and pneumatic cylinders.
Balluff's (Florence, KY) BOS 20K fiber-optic sensor uses teach-in capability to eliminate adjustment hassles and offer accurate sensor set-up. The versatile sensor has a compact 60 x 30 x 13 mm housing and is suitable for small parts detection, part feature checks, counting, and part positioning.
The H-100 E automatic bagger from Automated Packaging Systems (Streetsboro, OH) offers an anti-jam mechanism that implements sensors to stop the machine if a part is detected in the seal path of the unit.
efector Inc. (Exton, PA) has released a new family of master controller modules, slave modules, power suppliers, cables, software and accessories that will allow supplier's sensors and switches to be connected on a simple, two-wire bus system.
The LC-104 color sensor from Sentex (Santa Clara, CA) permits rapid analysis of up to four color signatures. Offers three levels of sensitivity that can be adjusted according to the shades of colors to be read.
Parker Hannifin, Pneumatic Div.'s (Richland, MI) Serial Addressable Manifold (SAM) Generation 3.0 is a communications module that allows valves, sensors and other devices on a packaging machine to communicate on a device-level network.
