New Technical Bulletin Aids with Replacement of Renco Encoders

If you're trying to replace a discontinued Renco brand rotary encoder, it can be a challenge. Especially when it comes to matching the Renco connector. Our new Technical Bulletin 532 makes that challenge a little easier.

New Technical Bulletin Aids with Replacement of Renco Connectors

Encoder Products Company is contacted frequently to assist with configuring rotary encoder models to replace units formerly manufactured by Renco Inc. Your first priority is to confirm compatibility of the basic electrical and mechanical features, such as pulse count, channels, output type, bore size, etc. The connector is often one of the last items to be conifigured. But, if not done correctly, it can be a point of frustration when installing the encoder.

To assist you in configuring a plug-and-play drop-in replacement for discontinued Renco encoders, we've developed a special connector option, designated as "SPEC779". There are some important factors to consider prior to ordering SPEC779; the details are spelled out in our new Technical Bulletin 532 (TB-532) "Applying SPEC779 When Replacing Certain RENCO Encoders."

EPC's SPEC779 option can be applied when replacing Renco models such as: RCH20, RHS20, RHS25, RHS21, RM21, RCM21, RS21, RCM15, RM15, RCML15, RMC1520, RS15, RHS15, and others.

White 8-Pin Connector (AMP770602-8) Cable

SPEC779 applies a flat, white 8-pin connector (AMP770602-8) to the end of the encoder cable as shown above. The cable can be ordered to length. SPEC779 can be applied to EPC Models 121, 260, 15T, 15H or 15S. Also, Line Driver (HV) and non-commutated output must be specified.

There are some dimensional differences between Renco's standard flat, black 8-pin connector (AMP103650-7) and EPC's flat, white 8-pin connector (AMP770602-8), as shown below. However, the correct pinout and spacing are used, and the EPC "SPEC779" connector plugs right into pin-headers often used in conjunction with the Renco servo-motor applications. When the Renco connector was used with an in-line connector, there are instances where a mating connector will be needed.

Kubler Slip Rings

The High Rotary Speed of the SRI085, 800 RPM, compensates the high speeds without difficulty. The load current dimensioning, which accepts up to 25 amperes, allows very short heating times and thus an optimal temperature regulation - even for shortest contact times. The new Kubler SRI085 slip ring has been designed for transmitting up to 3 load and 3 signal channels and meets, not least thanks to its almost maintenance-free

WEG Motors

Due to its Open Enclosure, the motor design permits higher output levels to be achieved when compared with totally enclosed motors, resulting in a cost effective solution for driven equipment. The motor enclosures are carefully designed with high-tech simulation tools to ensure low sound pressure levels, even with the high amount of air circulating inside the casting. The W40 motor is an effective option for applications which do not require
