Show all Safety Sensor Switches Manufacturers

Safety sensor switches are used in machines and other industrial applications to prevent accidental contact with live electrical connections. Safety sensor switches work together with hinged, sliding, or lift-off guards and barriers. The power supply to the machine is disconnected as soon as the guard is opened. Safety sensor switches include safety interlock switches, limit switches, and cable-pull limit switches. These safety sensor switches are available with a wide range of actuators, switch types, voltage and ampere ratings, contact materials, and termination types. A safety sensor switch can be used on machinery gates or doors guards where key removal brings the machine to a safe condition either immediately or at a pre-determined interval. The most common types of safety sensor switches are break-a-beam switches, interlocks, and tag out devices, perimeter guards, photoelectric safety sensors, safety blocks, safety interlock switches, and wireless safety. Safety sensor switches provide readily accessible emergency stop over a long linear distance such as exposed conveyor lines.

Function

Safety sensor switches function in a variety of ways. A majority of sensors respond to different physical phenomena, such as an ultrasonic sensor, infrared sensor, and microwave sensor. A safety sensor switch is used at different positions to manage for sensor safeguarding. To minimize failure and faults during disruption or tampering, the outputs of these sensors are individually linked to a central processing unit and alarm generator circuits by a plurality of redundant signal links. Safety sensor switches include proximity sensors with varying ranges of sensitivity and beam switches of varying size and means of activation. Industrial safety is managed by the presence of sensing devices, control machine operations protects personnel by detecting the presence of objects that could interfere with or be harmed by machinery. Safety sensors are designed and manufactured to meet most industry specifications.

 

Safety sensor switches are high-quality, dependable and cost-effective solutions for a variety of industrial safety applications and are modeled to meet all appropriate OSHA and ANSI standards. Safety sensor switches are used in machines and other industrial applications to safeguard equipment and prevent personal injury.
