Miniature Plug-in Relays

Type R

Class 8501 / Refer to Catalog 8501CT0301

8501 R relays are suited for use as logic elements and power switching output devices. The short stroke motion of the armature provides long mechanical life required for high speed operation of control systems. Different contact compositions allow these relays to be used in a variety of applications. Fine silver (gold flashed) and bifurcated crossbar (gold overlay silver) are suitable for high contact reliability and low level switching requirements. Silver tin oxide is best suited for inductive loads. Hermetically sealed relays can be used in adverse environments.

Pilot Light Option

An internal green pilot light is available in both AC and DC versions for positive indication of power to the coil.

Manual Operation Option

To speed circuit testing, a manual operator can be provided. The relay can be manually switched to simulate normal operation.
*
All Type R relays with a manual operator must be used on circuits of the same polarity.
