LP35 Intrinsically Safe Encoder
Position Sensors & Encoders
Sensata | BEI Sensors LP35 Intrinsically Safe Incremental Rotary Encoder is a low profile, durable encoder that provides excellent resistance to shock and vibration in a wide variety of heavy-duty applications. The Intrinsically Safe encoder offers a terminal box as well as other termination options, including an M12 connector or cable output. When used with a BEI Intrinsically Safe barrier, the encoder is suitable for use in a Division I, Class 1, Zone 0 explosive environment. The LP35 series of encoders also have a high protection level of IP66.
