Accu-Coder Encoders

AT LAST! A reliable modular encoder that requires no calibration, gapping, or special tools to install! EPC has taken the performance of modular encoders to a new level with the Model 121 Auto-Aligning Modular Encoder.

Accu-Coder Model 121 Modular Incremental Encoders Distributor

Model 121 (2.1" Diameter)

This new and innovative design provides simple, reliable, hassle free installation. Simply tighten the shaft clamp, install the mounting screws, and you're done.

The Model 121 incorporates the latest Optical ASIC technology for greatly enhanced performance. Common problems with other modular encoder designs are warping and deflection, caused by their extensive use of plastic, both of which are virtually eliminated by the Model 121's all metal construction.

If you are looking for Accu-Coder Model 121 Encoders, please call us at (800) 894-0412 or email us at info@clrwtr.com we will do our best to help you find the Accu-Coder through bore incremental encoders that you are looking for at the most competitive prices possible. If you are searching for Encoder Products Company (EPC) incremental motor mount encoder technical information (data-sheets) please use the datasheets or product selection guide page links.

For brushless servo motor applications, the Model 121 can be specified with three commutation tracks to provide motor feedback. The optional 100° C temperature capability allows servomotors to operate at higher power outputs and duty cycles. With its state-of-the-art technology and durable, all-metal construction, you can be confident your Model 121 Accu-Coder is the finest modular encoder available anywhere!

The maximum recommended motor axial endplay is ±0.010" for up to 1250 CPR, and ±0.005" for greater than 1250 CPR. Maximum recommended radial shaft runout is 0.002" for all resolutions.

Closely inspect the motor shaft to make sure that it is the correct size and free from all burrs and aberrations.

Applying pressure only to the hollow end of the encoder hub, slide the Model 121 encoder over the motor shaft until the base plate of the encoder rests firmly against the motor face. The encoder should slide easily onto the motor shaft or correct alignment may be compromised.

For longer shafts that extend through the encoder, a special tool is available from Encoder Products. This tool makes it easier to apply pressure only to the encoder hub.

While maintaining a light but firm pressure (approx. 2-3 lb.) on the back of the encoder hub, securely tighten the socket head screw in the clamping collar using a 5/64" hex wrench.

Install two screws (4-40 or M3 maximum) with the flat washers provided through the holes in the encoder base. Tighten each mounting screw 1/2 turn alternating between both screws until tight. (Suggested torque of approx. 160 oz-in) For additional security, a drop of Loctite 222 can be added to the threads of the screws.

Kubler Sensors

Kubler inclinometer IS60 permits 2-dimensional inclinations to be measured. Versions are available for the measuring ranges ±10°, ±45° or ±60°. The sensor has a standardised CANopen interface, which enables easy configuration and start-up. All the parameters are stored in the internal permanent memory. Can be supplied with customer-specific parameterising. Kubler is offering a special

TURCK Smart Plugs

When Switching on the Operating Voltage, the timer is reset. The initial state of the preset time is 100 ms off-delay. The SmartPlug is very easy to connect: it is plugged onto the M12x1 connector of a sensor and the connecting cable is connected to the other side of the SmartPlug. The sensor configuration has to meet the standards (1 +V (BN) 3 -V (BU) 4 output (BK) ). The SPT1 SmartPlug is a freely programmable timer for the direct adaptation to sensors
