SCHMERSAL BN20-11Z-M16 MAGNETIC REED SWITCH 101168014

Product Code: 101168014

The Schmersal BN20 Series Magnetic Reed Switch offers a robust solution for position sensing needs in industrial settings. Encased in durable aluminum, this rectangular switch features a bias magnet and can be actuated from the front or side. It supports both normally open (NO) and normally closed (NC) contacts, with an actuation distance ranging from 12 mm to 45 mm. Designed for high-performance applications, the switch can handle up to 250 VAC switching voltage, 3 A switching current, and has a maximum switching capacity of 120 W. Its two reed contacts ensure reliable operation with a long service life of over 1 million cycles per hour. With dimensions of 104 mm x 52 mm x 47 mm, the switch is compact yet powerful. Note that actuators are sold separately. The device operates effectively within a temperature range of -25°C to 90°C and boasts an IP67 rating for excellent protection against dust and water ingress as per IEC/EN 60530 standards. Ideal for engineers seeking precision and durability in their position sensors, the Schmersal BN20 series is an optimal choice for demanding environments where reliability is paramount.
