| The switches are "slack cable" style with "slow-make" contacts. The switches are not "positive transfer" and they do not latch in any position. They should not be used for an emergency stop applications. The action of these devices is that when the switch actuating arm is pulled by a cable the switch contacts will change state, that is, NO will be closed and the NC will go open. When the force on the cable is removed from actuator arm, spring pressure will return it to its normal position, while the contacts are held in position through a ratchet mechanism. The next time the cable is pulled, the action is repeated with the contacts being returned to their original state. The housing and cover are made from glass filled black poly carbonate. The mounting base and double end actuator arm are die cast from a high strength zinc alloy. All exterior steel components are made from #303 stainless. Switches are provided with two 1/2 NPT conduit openings. The total maximum cable length recommended his 200 feet with a maximum interval support of 10 feet. The life of these devices is in excess of 150,000 mechanical and 1,000,000 electrical operations. Each captive terminal on the replaceable contact block will accept (2)#14 AWG stranded wires and the contacts are gold plated to eliminate high resistance tarnishing. These devices can be found in various conveyor installations as well as other stations that require "pull-on", "pull-off" function that this provides. Their rugged construction and long-term reliability make these cables extremely well-suited to function within various industrial environments. | |||||||
