Digital Position Indicators
More customizable than standard indicators, these digital indicators have programmable features that help you adapt them to your application. Like other indicators, they track your machine component as it moves along a rotating spindle, lead screw, or other threaded shaft, which helps you adjust machinery with speed and precision. This saves time and prevents errors on process lines that you constantly adapt for different products, such as packaging lines.
Program the number you want added per revolution—you can use these indicators as a reference point or as a true measure of distance. To measure distance, match the indicator’s count per revolution to your lead screw’s threads per inch or thread pitch. You can adjust them to count from their original position or from their most recent stopping point, which is useful for repeating moves. They also have settings to work with clockwise and counterclockwise rotation, as well as vertical and horizontal shafts.
Rated IP67, all are sealed against dust and water, even if briefly submerged. They meet IEC 61326-1, which is an international standard for electromagnetic immunity and emissions.
Add shaft reducer bushings to adapt indicators to fit small diameter shafts. Stainless steel bushings are more corrosion resistant than black-oxide steel bushings, so they’re better in humid locations.

Linear Scales with Digital Readout

This digital readout (DRO) system displays precise positioning on one axis. For use with machines that perform dry machining and cutting applications, such as table saws, band saws, planers, and drill presses. These scales have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the scale is off. A zero-set button lets you start measuring at any point.

Pressure Transmitters for Compressed Air
- For Use With: Air, Argon, Nitrogen

- Connection Material: Nickel-Plated Brass
- Temperature Range: 25° to 120° F
With a pressure range common to most compressed air systems, use these transmitters to monitor your system's air pressure. Also known as transducers, these transmitters convert pressure to an electrical signal that can be interpreted by receiving devices such as remote displays and motor speed controls. They can also connect to a programmable logic controller (PLC) with two digital PNP switch outputs, so you can activate automated controls or alarms when a set pressure is reached. They have a digital display with buttons to change settings.
For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's pressure range and output signal. As pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.
UL and C-UL recognized components, CSA certified, and CE marked, they meet American, Canadian, and European safety standards.
Transmitters with current output connect using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.
Transmitters with voltage output connect using three wires—two wires into the power supply and a separate wire that sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.
Add a panel-mounting bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.

Read pressure directly at the source and send data remotely with one device. Also known as transducers, these transmitters convert pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. As pressure increases, the output signal from the transmitter will increase. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the pressure range and output signal of the transmitter. Transmitters will only provide accurate readings within the rated pressure range.
To change settings and receive error messages remotely from your PLC or computer, program one of the outputs to use IO Link. You need an IO-Link controller (not included) to connect to your interface.
All have an M12 plug to connect to M12 sockets. When using the analog current output they require two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. These transmitters can also connect using three wires to send an analog voltage output—two wires into the power supply and a separate wire that sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply. View switch wiring diagrams by selecting a part number and clicking Product Detail.
All transmitters are rated IP67 for protection from temporary submersion. UL and C-UL listed as well as CE marked, they meet strict American, Canadian, and European safety standards.
