Light Beam Safety Barrier Switches
Immediately cut power to machinery by breaking the light beam between the two barriers. Light beams can travel up to 32 feet between the transmitter and receiver. For a complete system, combine a transmitter, receiver, safety relay, and connectors (sold separately). Switches will automatically produce PNP or NPN signal output based on the device they are connected to. To selectively allow material to pass through the sensing field, you can program the system to allow one or more beams to be broken without shutting off your machine.
Note: These switches cannot be used with a full-revolution clutch press or machine. Use only with machinery that can consistently and immediately stop anywhere in its cycle.
Use safety relays when connecting these barrier switches to emergency stop switches.

Potentiometers
Vary electrical flow to control speed, volume, and light intensity. The number of turns affects the resolution—the higher the number, the better the control. Also known as variable output switches or rheostats. A knob is required (not included).
