Keep these small thermometers in your pocket or toolkit to spot check the temperature of dangerous, hard-to-reach, and moving surfaces without touching them.

Detect hot spots, leaks, moisture problems, and construction defects invisible to the eye.

To confirm the accuracy of noncontact temperature readings of dangerous and inaccessible surfaces, these thermometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Detect the presence or absence of an object moving at high speeds with a light beam. These switches have a longer sensing distance than proximity and ultrasonic switches.

Set these switches to delay activation by up to five seconds after detecting an object.

These switches have a receiver built into the housing, eliminating the need to align components and measure sensing distance during installation.

About half the size of standard photoelectric switches, these switches are good for use in tight spaces. They detect objects moving at high speeds with a light beam.

Mount these reflectors so they bounce the light beam from your photoelectric switch back to its sensor.

A slim design and a light beam that’s angled upwards allow these switches to sense objects from between conveyor rollers.

Also known as occupancy sensors, these controls turn lights on when movement is detected and off when an area is empty. They fit standard wall plates.

Control the brightness of lights from your smartphone.

Fine-tune motion-sensing light controls from your smartphone or tablet. Mounting on the ceiling gives these light controls a clearer view of the room than wall-mount sensors, so they switch reliably.

Detect motion near your light fixture to turn lights on and off. Compared to switch-mount motion controls that detect from a single wall, these controls have a better view of the entire space since they sense motion from above.

Protect sensors from damage and prevent tampering—these guards won’t trip or block the sensors.

Stream distance readings to your development board in real time. Set up these modules near your robotics, production lines, or liquid monitoring systems to capture changing positioning.
