Models
Model Range* Supply Voltage Output Response Time
M25UEQ8 Normal Speed: 500 mm (19.7") — —
High Speed: 250 mm (9.8") 10 to 30V dc
Normal Speed: 4.0 milliseconds
M25URBQ8 140KHz Bipolar (1 NPN & 1 PNP)
High Speed: 3.0 milliseconds
* M25U receivers may be wired for either of two speeds: Normal or High (see hookup diagrams, page 3). The Normal Speed mode offers a sensing range of 500 mm (19.7"). The
Normal Speed mode maximizes sensing energy, as is required in demanding environments. The High Speed mode offers a sensing range of 250 mm (9.8"). The High Speed
mode maximizes sensing response, as is needed in high-speed counting applications.

WARNING . . . Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.
These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A
sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner
Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

Notes 1. NPN < 200 µA for load impedance > 3 KΩ; for load current of 100 mA, leakage < 1% of load current
2. When mounting the M25U, care should be taken to acoustically isolate the emitter and receiver to eliminate
sound energy coupling between the sensor pair. This is best accomplished with elastomeric materials between
the sensor and rigid mounting brackets.
