Datasheet

•

Positive-opening safety contacts (IEC 60947-5-1), not dependent

upon springs

• Both safety contacts latch open when rope is pulled or in case of a

broken wire; requires manual reset

• Heavy-duty die cast metal housing, rated IP65, suitable for demanding

industrial environments

• Rope spans up to 6 m, 12 m or 20 m (20 ft, 40 ft, or 66 ft), depending

on model

• Both safety contacts are closed with normal rope tension; one contact

opens when rope is pulled, the other contact opens if rope breaks (or

if tension is reduced from normal amount)

• Some models include extra contacts for monitoring or to provide dual-

channel input to a safety device

• Indicator mark on switch shows when rope has proper tension for

operation

• Long life, switch rated at 1 million mechanical operations, minimum

• Five available models; all with latching outputs

•

Rope Pull Switches Important... Read This First Regarding the Use of Rope Pull Switches. In the United States, the functions that Banner rope pull switches are intended to perform are regulated by the Occupational Safety and Health Administration (OSHA). Whether or not any particular rope pull switch installation meets all applicable OSHA requirements depends upon factors that are beyond the control of Banner Engineering Corp.

Rope Pull Switches These rope pull switches are not safeguarding devices, in that they do not protect personnel from injury. They provide the same function as other types of stop switches. Rope Tension Indicator All five models feature “latching” operation. When the rope is pulled, the switch contacts 25/26 (and 45/46, depending on model) open and remain open until the built-in reset button is manually pulled to reset.

The wiring chamber is accessed via a cover plate (remove four screws). A conduit adapter is supplied to convert the 20 millimeter threaded entrance to 1/2-inch NPT. An accessory cable gland that fits the M20 thread is also available (see Accessories). Wiring. Install a jumper wire to place switch contacts 13/14 and 25/26 in series, as shown.
