Samson Type 4744 and 4744-2 Electric Limit Switch

Type 4744 Electric Limit Switch
For hazardous areas
 
For hazardous areas
 
The limit switch issues a limit signal whenever the valve travel exceeds or falls below a certain adjusted limit, especially when a valve has reached one of its end positions. This signal is suitable for transferring control signals, for example, to activate visible or audible alarms as well as for connection to centralized control or alarm systems.
 
Special features
 
•• One or two electric limit switches (possible to override)
•• High load capacity, for example, alternating current up to 500 V/10 A
•• Attachment to control valves with cast yokes or rod-type yokes according to IEC 60534-6-1 (NAMUR)
 
Versions
- Type 4744 (Fig. 1 and Fig. 2)
- Limit switch with one or two momentary-contact limit switches designed as a position switch conforming to EN 50041.
- Each contact is equipped with one NC contact and one NO contact, acting as a snap-action switch, which can also be switched as a single pole, double throw switch (SPDT).
- Type of protection: flameproof enclosure
- Type 4744-2 (Fig. 3)
- Limit switch with one momentary-contact switch for mounting to the rod-type yoke of Series V2001 valves.
- Type of protection: flameproof enclosure
