Optical Incremental Encoders - Pittman


Pittman Motors has introduced the PITTMAN E30C and E30D optical incremental encoders to satisfy the demands of volume original equipment manufacturers for encoders in precision-motion control applications.

The E30C and E30D encoders are small in diameter and low-profile, yet offer high resolutions and multichannel outputs in an economic design. The E30C and E30D are 5V, 2 and 3 channel optical encoders and available in 64 different configurations.

The modular encoder package is a compact 30-by-8 mm size with alternate mounting arrangements. Connections are provided thru a locking radial or optional axial connector. The E30C and E30D encoders operate from -20 to +85° C and weigh only 5.6 grams.

The E30C encoder has resolutions of 200, 250, 256, 400 or 500. It outputs two-channel quadrature signals that are TTL compatible. Operating frequency is 40 kHz (200 to 500 CPR).

The E30D has resolutions of 500, 512, 1000, 1024, 2000 or 2048. It outputs two-channel quadrature signals that are TTL compatible, with an optional third channel index output. Complementary outputs also are available. Operating frequency is 55 kHz (500-512 CPR), 110 kHz (1000-1024 CPR), or 220 kHz (2000-2048 CPR).
